Preparation of flower-like ZnO photocatalyst with oxygen vacancy to enhance the photocatalytic degradation of methyl orange

Organic pollutant degradation for micro-molecule product emission over SiO2 layers-coated g-C3N4 photocatalysts

“…5e and g). 43 It was obvious that 1.2-CN@SiO 2 still exhibited the best photocatalytic degradation efficiency, reaching 89% within 30 min, and the K ap was 0.02523 min −1 for 1.2-CN@SiO 2 . According to the liquid chromatography-mass spectrometry results, the intermediate products from antibiotics degradation on g-C 3 N 4 and 1.2-CN@SiO 2 were investigated, and the results are shown in Fig.…”

ZnO with p-Type Doping: Recent Approaches and Applications

“…Bi et al 70 studied the variation of oxygen vacancy in ZnO under different annealing conditions. The oxygen vacancy contents in ZnO annealed in air (N 2 + O 2 ), Ar, and N 2 environments are 24.84%, 34.64%, and 39.94%, respectively.…”

Enhanced visible-light photocatalysis in three-dimensional rose-like ZnO with oxygen vacancies and Ag nanoparticles

“…Oxygen vacancy is a kind of self-doping, which can effectively narrow the bandgap of ZnO and enhance photocatalytic performance under visible light irradiation. 6 Wang et al 7 prepared yellow ZnO with a high concentration of oxygen vacancies, and its absorption edge shifted obviously towards a longer wavelength. Ansari et al 8 enhanced the visible light photocatalytic activity of modified ZnO nanostructures by promoting oxygen vacancies, and the bandgap could be narrowed to 3.05 eV.…”
