Ultrafast charge separation in a WC@C/CdS heterojunction enables efficient visible-light-driven hydrogen generation

Abstract

The rapid recombination of photogenerated carriers and strong photocorrosion have considerably limited the practical application of CdS in the field of photocatalytic. Loading cocatalyst has been widely utilized to largely...

Noble-metal-free bimetallic nitride decorated CdS nanorods for photocatalytic hydrogen generation

“…3b, the binding energies of S 2p 3/2 (161.55 eV) and S 2p 1/2 (162.75 eV) in Ni 3 FeN (3 wt%)/CdS also shifted to higher binding energies by 0.4 eV than pristine CdS (161.15 and 162.35 eV). [28][29][30] The critical energy shift can be related to solid interaction between Ni 3 FeN and CdS. 31,32 Fig.…”

MoC@NC cocatalyst-modified ZnIn2S4 with strong 2D/2D hetero-interface interaction for efficient H2 evolution

“…[19][20][21][22] Recently, our team synthesized WC (WC@C) nanoparticles with carbon coatings as a co-catalyst to design visible light-induced CdS nanocomposites. 23 It was found that the prepared photocatalyst showed outstanding photocatalytic H 2 evolution, and the graphitic-like carbon possesses high conductivity and superb electron mobility, resulting in efficient charge separation. MoC nanoparticles have considerable potential as a HER cocatalyst because of their highly tunable orbital electronic structure.…”

Efficient visible light-initiated hydrogenation of nitrobenzene for chemoselective production of aniline, azoxybenzene, azobenzene and hydrazobenzene over CQDs/CdS nanocomposites

“…Hexagonal CdS is a binary chalcogenide with a band gap ranging from 2.1 eV to 2.6 eV corresponding well to the visible light region and has been extensively studied for a variety of photocatalytic reactions. [26][27][28][29][30][31] The deposition of CQDs on hexagonal CdS promotes the proton-coupled hydrogenation of nitrobenzene due to the presence of frustrated Lewis acid-base pairs (FLPs) in CQDs. 32 Via a delicate regulation of the reaction medium, the as-obtained CQDs/CdS nanocomposites show superior activity for the controllable hydrogenation of nitrobenzene into different products under visible light.…”
