Abstract

Spherical nanosized (type 1 and type 2) WO3 were prepared using CTAB surfactant mediated methods. The catalytic activity of these WO3 nanoparticles was tested for the ozonolysis of oleic acid, and compared with that of the bulk WO3 and commercial WO3 nano powder. Selectivity towards producing pelargonic and azelaic acid for these WO3 catalysts in decreasing order was: Type 2 WO3>type 1 WO3>bulk WO3>commercial nano powder WO3. The percentage yield of the reactions in decreasing order was: type 2 WO3>bulk WO3>type 1 WO3>commercial nano WO3. These results show that both of the synthesized nanoscale WO3 samples were more selective for this ozonolysis reaction than either the commercial WO3 nanopowder and bulk WO3.
