Sb 2 S 3 @carboxyl-modified COF S-scheme heterojunctions: the Sb–O–C interface enhances photocatalytic CO 2 reduction performance

Carboxyl-modified LZU-1 and Sb 2 S 3 form an S-scheme heterojunction with significant photocatalytic degradation and CO 2 reduction effects. IEF and Sb–O–C synergistically promote performance enhancement.
