Compositional and Defect Engineering of Metal Halide Perovskite‐Based Heterojunctions for Efficient Nitrogen Photofixation

Solar RRL, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 14, 2025

Designing innovative photocatalysts for nitrogen photofixation is becoming crucial the development of carbon‐neutral ammonia production. Metal halide perovskites (MHPs) provide a rich library materials with an easy tuning semiconductor bandgap in order to integrate them devices different functionalities. An under‐explored path their exploitation run wide range photoredox reactions mediated by solar light. Herein, heterojunction developed based on vacancy‐ordered double‐perovskite Cs 2 SnBr 6 and carbon nitride nanosheets demonstrate its ability running reaction produce under investigation done full /g‐C 3 N 4 system optimal providing outstanding evolution rate up 270 μmol g −1 h identified, which quantified means ion selective electrode. Mechanistic insight into obtained through combination advanced spectroscopy computational modeling. Efficient production stems from effective charge transfer perovskite vacancies enabled proposed absence self‐trapped excitons , also provides additional reactive sites bromide vacancies. This work paves way MHP‐based catalyst design strategy sustainable

Application of Lead-Free Metal Halide Perovskite Heterojunctions for the Carbohalogenation of C–C Multiple Bonds

Organic Letters, Journal Year: 2025, Volume and Issue: unknown

Published: April 1, 2025

A graphitic carbon nitride/lead-free double perovskite heterojunction (g-C3N4/Cs2AgBiCl6) has been adopted as a heterogeneous photocatalyst under visible light irradiation. The employed material enabled the atom transfer radical addition-type carbohalogenation of multiple C-C bonds, including (internal) alkenes and alkynes, with alkyl halides. protocol showed remarkable functional group tolerance, compatible late-stage functionalization natural pharmaceutical derivatives, could be easily scaled up, delivering >1 g desired products.
