Tailoring heterostructures of Ag/Cu2O hybrids for enhanced photocatalytic degradationdegradation

Engineering a Highly Improved Porous Photocatalyst Based on Cu2O by a Synergistic Effect of Cation Doping of Zn and Carbon Layer Coating

“…However, the photocatalytic activity of Cu 2 O has been limited due to the relatively lower separation efficiency of photoinduced charge carriers and the instability related with the intermediate valence state of Cu­(I) and photocorrosion issues . Engineering heterostructures based on doped Cu 2 O and other materials (such as TiO 2 , ZnO, and metal), which can provide a separation path for the photoinduced electrons and holes, may be able to solve the above issues . Nevertherless, studies on fabricating a material which can combine the merits of cation doping and heterostructures have not been given sufficient attention due to the difficulties in the rational design of such materials.…”

Construction of a flower-like S-scheme Bi2WO6/BiOCl nano-heterojunction with enhanced visible-light photocatalytic properties

“…Meanwhile, the photo-degradation of RhB was observed to follow pseudo-first-order kinetics: 51,52 Àln(C/C 0 ) = kt, where C 0 and C are the RhB concentration after 30 min of dark reaction and at different light irradiation times, respectively. Here, t is the light irradiation time and k indicates the RhB degradation rate constant.…”

Cu2O as an emerging semiconductor in photocatalytic and photoelectrocatalytic treatment of water contaminated with organic substances: a review

“…This enhanced performance can be attributed to the electron sink effect of silver nanoparticle. 88 In other works, the formation of a quaternary magnetic nano-junction involving Cu 2 O, BiOCl, g-C 3 N 4 and Fe 3 O 4 was used to study the effects of visible light and solar light in the degradation of pharmaceuticals from wastewater. Kumar et al, 83 explored the possibility of degrading sulfamethoxazole (SMX) by utilizing light from the sun and visible light as both natural and articial light source.…”
