ZnO-based heterojunction catalysts for the photocatalytic degradation of methyl orange dye.

ABSTRACT: In this study, a variety of ZnO-based heterojunctions with disparate wt.% doping of WO₃ and BiOI have been prepared for the photodestruction of methyl orange (MO) dye in aqueous solution. The composites were analysed by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, optical studies, and nitrogen adsorption-desorption isotherms. The SEM images revealed non-uniform surfaces of the ZnO-BiOI based composites while mostly nodular morphology was observed for all three samples of ZnO-WO₃. As the WO₃ loading increased, more clustering was detected. The analysed samples exhibited characteristic peaks representative of the triclinic phase of WO₃ and the hexagonal wurtzite structure of ZnO, while the diffractogram obs
