Enhanced photocatalytic activity of p-n-n heterojunctions ternary composite Cu2O/ZnO/Ag3PO4 under visible light irradiation

Synthesis and visible-light photocatalytic degradation of Ag3PO4/AgBr/hydroxyapatite ternary nanocomposites prepared from oyster shells

“…The key to improving the activity and stability of silver phosphate is to explore and construct new and efficient silver phosphate composite photocatalysts. To this end, researchers have developed a series of complexes by combining materials with silver phosphate, such as CeO 2 , 1 TiO 2 , 2 AgX, 3 GO, 4 Ti 3 C 2 , 5 CdWO 4 , 6 BiVO 4 , 7 ZnO, 8 CuO 9 and g-C 3 N 4 . 10 The results show that an effective composite material is beneficial to the transfer of photogenerated carriers in the material and can effectively inhibit electron–hole recombination, 11 thus improving the photocatalytic activity of the material.…”

Current Developments in the Effective Removal of Environmental Pollutants through Photocatalytic Degradation Using Nanomaterials

“…Many factors are responsible for the deactivation of the photocatalysts, such as the loss of photocatalyst mass, especially during the washing/purification process. It has been reported that some amounts of rod-shaped ZnO stacking occur on Cu 2 O/Ag 3 PO 4 during filtration [204]. Leaching of dopants usually occurs during the reaction due to photoetching [205].…”

Environmental Friendly Catalysts for Energy and Pollution Control Applications

“…Several factors lead to the deactivation of the photocatalyst. These include (1) loss of photocatalyst mass especially during the washing/purification process, for example, the research reported by Taddesse et al [125], where the Rod-like ZnO stacking on Cu 2 O/Ag 3 PO 4 , which has lost some quantity during filtration; (2) leaching of dopants is also a common phenomenon that normally happens during the reaction due to photo-etching as experienced by Zhang et al [126], when the synthesized ZnO catalyst undergo photodecomposition after three cycles in degradation of Rhodamine B; (3) residual pollutant and/or organic intermediates that adsorbed on the surface of photocatalyst. This normally occurs for the nanosized-photocatalyst with high porosity surface.…”
