S‐Modified Graphitic Carbon Nitride with Double Defect Sites For Efficient Photocatalytic Hydrogen Evolution

Small, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 3, 2024

Abstract Graphitic carbon nitride (gC 3 N 4 ) is an attractive photocatalyst for solar energy conversion due to its unique electronic structure and chemical stability. However, gC generally suffers from insufficient light absorption rapid compounding of photogenerated charges. The introduction defects atomic doping can optimize the improve carrier separation efficiency. Herein, high efficiency photocatalysis hydrogen evolution in visible achieved by S‐modified double‐deficient site strategy. Defect engineering forms abundant unsaturated sites cyano (─C≡N), which promotes strong interlayer C─N bonding interactions accelerates charge transport . S tunes semiconductors, formation C─S─C bonds optimizes electron‐transfer paths bonding, enhances light. Meanwhile,C≡N acts as electron trap capture photoexcited electrons, providing active reduction H + hydrogen. photocatalytic SDCN (1613.5 µmol g −1 h 31.5 times higher than that pristine MCN (51.2 ). situation transfer mechanism photocatalysts are investigated detail a combination experimental theoretical calculations.

En Route to Recyclable Semi-Heterogeneous Photocatalysis with Photoinert CeCl₃

ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(10), P. 7664 - 7673

Published: May 2, 2024

Our study proposes an approach to semiheterogeneous photocatalysis, focusing on recyclability challenges. We developed a method employing visible light with photoinert anhydrous CeCl3, rendering it into reusable photocatalyst. Despite being and insoluble in organic solvents, CeCl3 formed transient charge transfer complex acetonitrile, denoted as - NXS (NBS or NCS), due the strong oxophilicity of trivalent cerium toward oxygen. This facilitated visible-light absorption, leading photoexcitation Ce(III) complexes conversion centers potent reductants, donating electrons NXS. As proof concept, we demonstrated reactions where NXS, upon accepting electrons, generated halide radicals, allowing synthesis gem-dihaloketones under sunlight from terminal aromatic alkynes via C–X cross-coupling reactions. Significantly, exhibited without notable decomposition, by its regeneration isolation through simple filtration postreaction, underscoring potential for prolonged use.
