Modified WO3 nanorod with Pt nanoparticle as retrievable materials in catalytic and photocatalytic aerobic oxidation of alcohols
Source abstract
Abstract
This study has focused on catalytic and photocatalytic oxidation of aromatic alcohols using WO3 nanorod and a series of Pt/WO3 nanocomposite Pt nanoparticles was loaded on WO3 nanorod with several mass ratios 0.1, 0.2, and 0.3 via a photoreduction process (PRP) and characterized by TEM, FE-SEM imaging, EDAX, XRD, DRS, ICP, and XPS. WO3 nanorods were obtained monodispersed with average 40-nm diameter and square cross section without significant size change by the loading of platinum nanoparticles on it. Progress of oxidation reaction was monitored by GC and the yield of aerobic photocatalytic oxidation of alcohols reached up to 98% for Pt/WO3 and 69% for WO3 while, no oxidation was detected in the absence of light. The highest photocatalytic performance was obtained for mass ratio 0.2 with the selectivity >99%. So, this nanocomposite has potentials to be used as high-performance heterogeneous catalyst and photocatalyst under visible light irradiation with advantages of high activity, high selectivity, and reusability.
