Synthesis of CeO₂/ZrO₂/ZnO nano alloy oxide and investigation of photocatalysis of naphthol orange under sunlight

Abstract

Novel metal-like cerium- and zirconium-doped ZnO photocatalysts were prepared herein with various proportions of molar ratios via a cost-effective co-precipitation method.

Biosynthesis of JC-La2CoO4 magnetic nanoparticles explored in catalytic and SMMs properties

“…As the amount of catalyst dose increased, the amount of adsorbed dye on the surface of the catalyst increased. Now the adsorbed dye molecule promptly reacts with ROS (reactive oxygen species) 57 – 59 . In the present study increased the catalyst dosage from 0.025, 0.05, 0.1, and 0.2 g/20 mL, the degradation percentage of MB dye initially increased which may be attributed to the active ROS sites generation.…”

All-inorganic lead halide perovskites for photocatalysis: a review

“…TiO 2 was originally used as a photocatalyst to break down water into H 2 and O 2 . 5 Different catalysts have been employed, including metal oxides (ZnO, WO 3 , Co 2 O, CeO 2 ), 6–8 metal sulfides (MoS 2 , WS 2 , Co 3 S 4 ), 9–14 nitrides (C 3 N 4 , GaN), 15,16 phosphides (InP, Ni 2 P, CoP, FeP), 17–26 and carbides (C 3 N 4 , rGO, MoC). 27–31 Photocatalysts with band gap ( E g ) larger than 3 eV, such as TiO 2 , ZnO, and MnS, have a fatal flaw: they can only be activated by UV light and cannot respond to a wide range of visible light regions.…”

Vanadium promoted ZnO films: Effects on optical and photocatalytic properties

“…Sol–gel technique [12], electrodeposition [13], chemical bath deposition [14], hydrothermal synthesis [15], thermal plasma [16], atomic layer deposition [17] or thermal evaporation [18], sputtering or radio frequency reactive magnetron sputtering [19], air plasma spraying [20,21], ablation techniques [22], and co-precipitation [23] have all been used to prepare ZnO thin films. Some researchers have reported the use of two-step processes, such as spin coating followed by growth treatment [24].…”
