Catalytic oxidation of 4-tert-butyltoluene to 4-tert-butylbenzaldehyde over cobalt modified AlPO-5 zeolite Weiyou Zhou · Jiugao Pan · Fu’an Sun · Ke Huang · Mingyang He Techniques Powder X-ray diffraction (XRD) patterns of the as-synthesized samples were obtained using a Rigaku D/max 2500 PC X-ray diffractometers with Cu-Kα (1.5402 Å) radiation at 10 min−1. For the scanning electron microscopy (SEM) study of the samples, a JEOL JSM-6360LA scanning electron microscope was used. The IR spectra were recorded on a Nicolet PROTÉGÉ 460 FTIR spectrometer in the region 4000~400 cm−1 using KBr pellets. Fig. S1 SEM pictures of CoAPO-5 sample Fig. S2 FTIR spectra of CoAPO-5 sample
