Boosted CO₂ Photoreduction Performance by CdSe Nanoplatelets via Se Vacancy Engineering.

ABSTRACT: 2D metal-chalcogenide nanoplatelets (NPLs) exhibit promising photocatalysis properties due to their ultrathin morphology, high surface-to-volume ratio, and enhanced in-plane electron transport mobility. However, NPLs, especially cadmium chalcogenides, encounter challenges in CO₂ photoreduction due to insufficient solar energy utilization and fast recombination of photogenerated charge carriers. Defect engineering offers a potential solution but often encounters difficulties maintaining structural integrity, mechanical stability, and electrical conductivity. Herein, by taking two monolayers (2ML) CdSe NPLs as a model system, selenium (Se) vacancies confined in atomic layers can enhance charge separation and conductivity. A straightforward approach to create Se vacancies in variou
