摘要

•ZIF-67-derived hollow CsPbBr3/Co3O4 was prepared by microwave-assisted method.•Efficient photoconversion of CO2 was achieved upon the CsPbBr3/Co3O4 photocatalyst.•Oxygen vacancies and enhanced built-in electric fields existed in p-n junction.•Formed Cs-O bonds acted as the charge transfer channels at the interface.
