Elemental doping inhibits surface-state-mediated charge carrier trapping for promoting photocatalytic selective oxidation

Abstract

Surface-state-mediated trapping process, a dominant consumption pathway of photoinduced charge carrier, sometimes plays a detrimental effect on gaining high-efficiency photocatalytic solar energy utilization. Herein, taking Bi2O2CO3 as a typical prototype,...

Activating black phosphorene's inert basal plane via nonprecious metal–nonmetal co-doping for visible-light-driven photocatalytic H2 evolution

“…This interaction enhances the stability of the doped structure. 32,33 On the other hand, the intrinsic charge transfer behaviour of the basal plane can be modified by introducing nonmetallic dopants with different valence electrons into the basal plane or by exploiting the electronegativity difference between the doped nonmetallic atoms and the basal plane atoms, which can ultimately enhance the photocatalytic HER performance. [34][35][36] Recently, Cui and colleagues have identified that BiOCl co-doped with S and Mo exhibits enhanced photocatalytic activity for pollutant degradation.…”

Dual-functional photocatalyst of CoSx/Cd0.7Zn0.3S without noble metals for efficient selective benzaldehyde synthesis coupled with H2 production

“…17,18 To ameliorate this, various strategies have been employed, such as cocatalyst modification, element doping, and heterojunction construction. [19][20][21][22] Noble metals with high function and low Fermi levels, such as Pt, 23 Ag, 24 and Au, 25 are common H 2 production cocatalysts, and can provide active sites for electron transport and reduce the H 2 production overpotential. Efficient H 2 production is conducive to promoting the oxidation of BA; for example, Ruberu et al demonstrated that loading Pt on CdS nanorods significantly promoted the activity of photocatalytic BAD synthesis, which was ascribed to the fact that the Pt cocatalyst accelerated the reaction kinetics of H 2 production.…”
