Covalent triazine-based frameworks confining cobalt single atoms for photocatalytic CO2 reduction and hydrogen production
文献摘要：
Single-atom catalysts(SACs)have emerged as an advanced frontier in heterogeneous catalysis due to their potential to maximize the atomic efficiency.Herein,covalent triazine-based frameworks(CTFs)con-fining cobalt single atoms(Co-SA/CTF)photocatalysts have been synthesized and used for efficient CO2 reduction and hydrogen production under visible light irradiation.The resulted Co-SA/CTF demonstrate excellent photocatalytic activity,with the CO and H2 evolution rates reaching 1665.74 μmol g-1 h-1 and 1293.18 μmol g1 h-1,respectively,far surpassing those of Co nanoparticles anchored CTF and pure CTF.A variety of instrumental analyses collectively indicated that Co single atoms sites served as the reac-tion center for activating the adsorbed CO2 molecules,which significantly improved the CO2 reduction performance.Additionally,the introduction of Co single atoms could accelerate the separation/transfer of photogenerated charge carriers,thus boosting the photocatalytic performance.This study envisions a novel strategy for designing efficient photocatalysts for energy conversion and showcases the application of CTFs as attractive support for confining metal single atoms.
