One-Step Fabricated Sn Particle on S-Vacancies SnS to Accelerate Photoelectron Transfer for Sterling Photocatalytic CO Reduction in Pure Water Vapor Environment.

Promoting the proton-coupled electron transfer process in order to solve the sluggish carrier migration dynamics is an efficient way to accelerate the photocatalytic CO reduction (PCR) process. Herein, through the reduction of Sn by amino and sulfhydryl groups, Sn particles are lodged in S-vacancies SnS nanosheets. The high conductance of Sn particles expedites the collection and transport of photogenerated electrons, activating the surrounding surface of unsaturated sulfur (S ) and thus lowering the energy barrier for generation of *COOH.

Deciphering the Superior Electronic Transmission Induced by the Li-N Ligand Pairs Boosted Photocatalytic Hydrogen Evolution.

Atomic level decoration route is designated as one of the attractive methods to regulate both the charge density and band structure of photocatalysts. Moreover, to enable more efficient separation and transport of photocarriers, the construction of novel active sites can enhance both the reactivity and electrical conductivity of the crystal. Herein, an Li-N ligand is constructed via co-doping lithium and nitrogen atoms into ZnIn S lattice, which achieves a promoted photocatalytic H evolution at 9737 µmol g h .

Insights into the Operation of Noble-Metal-Free Cocatalyst 1T-WS -Decorated Zn Cd S for Enhanced Photocatalytic Hydrogen Evolution.

Due to inefficient charge separation and low surface catalytic conversion efficiencies, cocatalysts are required for achieving photocatalytic hydrogen evolution. Being a noble-metal-free cocatalyst, metallic 1T-WS with excellent conductivity can function for this reaction. Herein, 1T-WS /Zn Cd S is constructed via a simple and feasible grinding approach.
