Characterization and Comparison of WO₃/WO₃-MoO₃ and TiO₂/TiO₂-ZnO Nanostructures for Photoelectrocatalytic Degradation of the Pesticide Imazalil.

ABSTRACT: Tungsten oxide (WO₃) and zinc oxide (ZnO) are n-type semiconductors with numerous applications in photocatalysis. The objective of this study was to synthesize and characterize different types of nanostructures (WO₃, WO₃-Mo, TiO₂, and TiO₂-ZnO) for a comparison of hybrid and pure nanostructures to use them as a photoanodes for photoelectrocatalytic degradation of emerging contaminants. With the aim of comparing the properties of both samples, field emission scanning electron microscopy (FE-SEM) and confocal laser-Raman spectroscopy were used to study the morphology, composition, and crystallinity, respectively. Electrochemical impedances, Mott-Schottky, and water splitting measurements were performed to compare the photoelectrochemical
