Abstract

A novel dual-confinement photocatalyst based on Co3S4 quantum dots and NiAl-LDH enables efficient CO2 photoreduction by coupling charge separation with surface activation. An interfacial electric field drives electron accumulation at hydroxyl-rich confined sites, lowers the COOH* formation barrier, and affords a CO evolution rate 17.8-fold higher than that of pristine NiAl-LDH.
