Surface engineering of copper sulfide-titania-graphitic carbon nitride ternary nanohybrid as an efficient visible-light photocatalyst for pollutant photodegradation

A p–n Junction by Coupling Amine-Enriched Brookite–TiO2 Nanorods with CuxS Nanoparticles for Improved Photocatalytic CO2 Reduction

“…The binding energies of 932.7 and 952.7 eV are ascribed to Cu 2p 3/2 and Cu 2p 1/2 , respectively, a typical peak location of Cu 2+ in CuS [ 14 , 20 ]. A weak satellite peak around 944 eV further indicates the presence of Cu 2+ [ 53 ]. These results indicate that Cu + was completely oxidized to Cu 2+ after the photocatalytic reaction in this photocatalysis system, which might weaken the cycling performance of the NH 2 -B-TiO 2 -Cu x S composite.…”

Rational construction of ZnO/CuS heterostructures-modified PVDF nanofiber photocatalysts with enhanced photocatalytic activity

“…[42][43][44] Accordingly, the p-n heterojunction prepared by coupling CuS and ZnO nanomaterials can signicantly improve the catalytic activity of ZnO under visible light irradiation. [45][46][47] In addition, in order to make the photocatalysts recyclable and reusable, electrospun nanobers acting as a base material for mounting nanocomposite photocatalysts are drawing numerous interests. [48][49][50] Despite the fact that nano-powder photocatalysts demonstrate higher photocatalytic efficiency than membranes due to their large specic surface area, there are still many problems in practical applications.…”
