Construction of a heterojunction with fast charge transport channels for photocatalytic hydrogen evolutionviaa synergistic strategy of Co-doping and crystal plane modulation

Abstract

Carrier spatial separation efficiency and active electron density are key factors affecting photocatalytic hydrogen evolution activity. Heterojunction catalysts with fast charge separation and directed electron transport systems were successfully prepared...

Atomically Dispersed Pt on CdS Nanosheets for Photocatalytic Evolution of H2 and 1,1-Diethoxyethane from Ethanol

“…41-1049) (Figure 1b). 29,30 Among them, the (002) facet shows the highest peak intensity, indicating that the 2D CdS nanolayers could afford a large amount of coordinatively unsaturated S centers, which contributes to anchor Pt SSCs. Then Pt SSCs were isolated onto CdS (Pt SS -CdS) through a surface photoinduced reduction process, and the loading amount of Pt species was 0.19 wt % (Table S1).…”

Recent progress on the photocatalytic hydrogen evolution reaction over a metal sulfide cocatalyst-mediated carbon nitride system

“…Numerous active sites can be produced to speed up the surface reaction rate by controlling the cocatalyst's shape, size, and composition. 86,87 (3) Inhibit photocorrosion and improve photocatalyst stability. The electrons or holes generated by semiconductors can not only participate in the redox process of water, but may also react with themselves and cause photocorrosion.…”

Fabrication of a P–Si/ZnO heterojunction based on galvanic cell driven and the complete degradation of RhB via fast charge transfer

“…7 However, in photocatalytic degradation technology, using a single semiconductor material encounters issues of poor stability and inefficient utilization of photogenerated carriers, leading to photo corrosion and low catalytic degradation efficiency. 8–12 Therefore, it is customary to construct semiconductor heterojunctions with controllable structures for application in photocatalytic degradation technology. For instance, Li et al 13 prepared g-C 3 N 4 /TiO 2 composite materials by the seed-induced solvothermal method for the degradation of methyl orange under visible-light irradiation.…”
