While investigating the features that define transition metal oxide catalysts, which are active for many hydrocarbon oxidation reactions, Wang et al. mimicked the catalytic sites by means of molybdenum and tungsten oxide molecules charged with one or two additional electrons. They discovered spectroscopically that the singly or the doubly-charged M3O9 species (a most stable species), where M is molybdenum or tungsten, has delocalized electronic states typical of aromatics. Theoretical first-principles electronic structure calculations confirmed the delocalization of the additional electrons and explained the unusual stability of the anionic species. Moreover, they led to the hexagonal symmetry or ring structure shown in the figure. This is the first theoretical prediction and experimental observations of this phenomenon, a phenomenon that could have implications for the synthesis and reactivity of transition metal oxide clusters.

To simplify the complexity and understand the origin of reactivity in oxides, model systems are prepared and studied. The simplest approach has been to examine the chemistry of single crystal surfaces or, on the contrary, quasi-amorphous or polydispersed oxide clusters. For the first time, a collaborative team from Pacific Northwest National Laboratory (PNNL) and the University of Texas prepared monodispersed oxide clusters supported on another oxide. This unique approach involved direct sublimation from solid tungsten trioxide (WO3) and resulted in the successful stabilization of monodispersed cyclic trimers (WO3)3 on a well-characterized, single-crystal titanium oxide substrate (TiO2) (110). The (WO3)3 trimers were successfully imaged using scanning tunneling microscopy; their empty states resembled those of gas phase cyclic (WO3)3. Additional characterization efforts employed mass balance and x-ray photoelectron spectroscopy to determine the cluster mass, stoichiometry, and tungsten oxidation state. Preparation of such monodispersed, model systems allows for further exploration of their catalytic activity in an ensemble averaged manner. Ongoing studies have already shown that the (WO3)3 clusters are catalytically active toward formaldehyde polymerization and 2-butanol dehydration. Solid state quantum mechanical calculations provide a detailed understanding of the cluster electronic structure and binding to TiO2(110). Their catalytic activity is being investigated.

A dramatic enhancement of activity and selectivity of oxidation catalysts such as palladium metal is observed when the metal atoms are diluted with gold. These alloys catalyze a range of important energy-demanding or producing applications, from vinyl acetate synthesis to hydrogen fuel cells to pollution control. However, why gold promotes palladium is poorly understood and, in general, how catalytic promotion occurs is mostly unknown. Using the vinyl acetate synthesis from ethylene, oxygen and acetic acid as a model reaction, Professor D. Wayne Goodman at Texas A&M University found that the level of enhancement is determined by the way the palladium atoms are spatially arranged on the surface of the alloy. He concluded that only those surfaces that contain well dispersed pairs of palladium atoms display catalytic activities 40 times those of pure palladium metal. This particular arrangement is promoted by a very open type of gold surface, gold (100). Other arrangements are not optimal. For example, the closepacked gold (111) surface arranges palladium as single isolated atoms, and the best performance delivered was just 10 times that of pure palladium. To answer the question of why pairs of palladium atoms performed better than single atoms, he used various spectroscopic, C2H4 + ½ O2 + CH3COOH microscopy and chemical techniques to infer the CH2=CH—OCOCH3 + H2O distribution of atoms and chemical bonds. He discovered that the two main functionalities involved in this reaction (the vinyl group and acetate groups) must be brought within 3.3-4.1 angstrom of each other, which only the palladium pairs embedded in the gold (100) surface are able to do.

R. Bergman and K. Raymond at the Lawrence Berkeley National Laboratory have demonstrated entropy-driven intramolecular rearrangements catalyzed by the constraints imposed by chiral nanovessels. These host molecules consist of M4L6 naphthalene-based self-assemblies with hydrophobic interiors and hydrophilic exteriors. The catalytic host was shown to accelerate the rearrangement of enammonium cation (B-1) to the iminium cation B-2, followed by hydrolysis to yield the unsaturated aldehyde B-3. The restricted space forces the substrate into reactive conformations, accelerating the rearrangement by up 850-fold. Bergman R., Raymond K., Angew.

Fiedler, K. N. Raymond, R. G. Bergman, 2004 Single-Molecule Supported Catalyst Researchers have strived to synthesize hybrid catalysts that combine the advantages of highly selective homogeneous catalysts and highly stable and separable heterogeneous catalysts, in order to reduce the huge energy consumption associated with separating the products and the catalysts from the reaction mixtures. Thus they have pursued supported organometallic complexes that could be anchored on inorganic supports without the loss of catalytic activity or selectivity and with the gain of structural uniformity and integrity. Profs. James Haw at the University of Southern California and Bruce Gates at the University of California-Davis have recently provided the first structural and theoretical evidence of a mononuclear rhodium complex with ethylene ligands that is distributed molecularly and uniformly throughout the cages of zeolite Y. Molecular dispersion and structural uniformity could in principle prevent product degradation caused by secondary reactions and enhance catalytic site uniqueness and thus selectivity. This result, published as a coverpage article, is a significant contribution to the burgeoning field of surface organometallic chemistry. The picture shows the rotation of the ethylene ligands about the Rh+ center (green sphere). Haw, J., Gates, B., et al., Angewandte Chemie International Edition 2006, 45, 574-576 Electrocatalytic Activity of Platinum-Monolayer Alloys Ea In low-temperature fuel-cells, the cathodic oxygen reduction reaction (ORR) is very slow and critically dependent on the composition and structure of the platinum alloy electrodes. Adzic and Mavrikakis have demonstrated for the first time that Pt monolayers epitaxially grown on single crystal metal substrates possess higher activity than the best known electrodes, but with much less content of Pt. Investigation of the atomic and electronic structures of the Ptmonolayer alloys and the mechanism of the ORR led to a new discovery. The activity for the ORR displays a volcano-plot behavior with maximum for PtML/Pd(111). For this alloy, the Pt metal strain and thus the center of the d-band are such that the two critical steps – the 4-electron oxygen reduction and the hydrogen insertion–present an overall minimum in activation energy (fig. at top right). This work was carried out by R. Adzic at the Brookhaven National Laboratory (electrochemistry and surface chemistry), National Synchrotron Light Source (EXAFS, XANES), and by M. Mavrikakis (DFT calculations) at the U. Wisconsin, DOE-NERSC, NPACI and PNNL supercomputing centers. R. Adzic, M. Mavrikakis, et al., Angew. Chem. Int. Ed.

Chemical stability and long term durability are two of the greatest technical challenges for both electrodes in hydrogen fuel cells, but are particularly so for the cathode where the oxygen reduction reaction occurs. Until now, the design of platinum alloy electrocatalysts has been guided primarily by empirical information. Recently, Professor Perla Balbuena at Texas A&M University described a theoretical approach involving density functional theory applied to clusters and slabs of model bimetallic alloys of platinum with iridium, palladium, rhodium, nickel, and cobalt. She modeled the interfacial chemistry, verified that the primary dissolution mechanism is electrochemical, and, for the first time, predicted the trends in the stability of the bimetallic nanoparticles. This fundamental understanding could greatly influence the future design of fuel cell electrodes. Z. Gu and P. Balbuena, J. Phys. Chem. A, Letters, published on the web on 7/22/2006 Figure 4.

Leung, K. N. Raymond, R. G. Bergman, 2003-4 No Reaction Intrinsic Motions of Proteins Underlie Catalysis Static pictures of protein structures (typically derived from x-ray crystallography) are so prevalent that one usually forgets that they are dynamic molecular machines. Characterizing the intrinsic motions of enzymes is necessary to fully understand how they work as catalysts. Prof. Dorothee Kern of Brandeis University has quantitatively determined the structural dynamics of cyclophilin A (CypA) in the microsecond to millisecond timescale both while the enzyme is involved in the catalytic isomerization of prolyl peptide bonds, and when it is free in solution. She correlated specific conformational changes, flexional modes in the protein backbone, and motions of residues, with the kinetics of the catalytic cycle, and she made a remarkable discovery. Contrary to the belief that conformational changes are coincident with or facilitated by the binding of the reacting substrate to the enzyme, the protein motion between conformational sub states occurs a priori with modes that are intrinsic to the structure and are determined by the amino acid sequence. That is, the protein samples the conformational sub states before the ligands bind. Catalytically active proteins evolve a set of sub states that are critical for the catalytic function.

In near-surface alloys, a solute metal is present near the surface of a host metal in concentrations different from the bulk. Such nanostructures possess unique electronic properties that in turn affect their surface catalytic properties. M. Mavrikakis used density functional theory calculations to discover a new class of alloys that can yield superior catalytic behavior for hydrogen-related reactions. Some of those alloys, e.g., Ni/Pt(111) and V/Pd(111), bind atomic hydrogen (H) as weakly as the noble metals (Cu, Au) while, at the same time, dissociate H2 much more easily. This unique behavior may permit those alloys to serve as low-temperature, highly selective catalysts for hydrogen fuel cells and for hydrogen storage.
