چکیده

The aim of this study was to investigate and overcome thiophene sulfur
contaminants using high purity synthesized ZnO/WO3 nanocomposite and
homogeneous composition by Pechini sol-gel method at low temperature.
Zinc oxide is one of the most dynamic elements known in this field, its
presence together with tungsten oxide prevents the crystallization of tungsten
nanoparticles. Fuzzy structure, percentage of elements, surface morphology,
penetration reflection spectrum, and photocatalytic degradation of thiophene
were determined by XRD, EDS, SEM, and DRS analyses, respectively. DRS results
indicate high light absorption, reduced bandgap due to the presence of WO3 after
combination with ZnO, and increased efficiency. Finally, the nanocomposite with
more than 84% efficiency resulted in the degradation of oxidative desulfurization
of thiophene after 150 min under visible light.
