AbstractGrowth study of nano sized Bismuth oxy chloride (BiOCl) Thin film on Carbon nano tube
carpet (CNTs) was studied by Metal Organic Chemical vapour deposition (MOCVD)
method (Figure 1).This is one of the best methods for depositing thin metallic layers with
precisely controlled thickness. Nano sized bismuth (NBs) crystals were synthesized
from solution containing Bismuth chloride (BiCl3) in Acetone (CH3-CO-CH3). Self
assembly of nano bismuth crystals was observed on the CNT surface. Various
synthesis parameters were investigated to achieve better depositions, as they
significantly affect the formation of self-assembled nano-crystalline bismuth [1].
Crystalline NBs was characterized by X-ray diffraction (XRD), Field emission scanning
electron microscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDS),These
analyses confirm the Bismuth nanometer-sized crystal structures are in the form of
tetragonal BiOCl with a mean wall thickness similar to the diameter of CNT i.e 80–90
nm (Figure 2).
