Atomic-level interfacial engineering of a Zr-In 2 S 3 /g-C 3 N 4 Z-scheme heterojunction for enhanced photocatalytic CO 2 reduction

In situ growth of Zr-In 2 S 3 on g-C 3 N 4 nanosheets forms an atomic-level Zr–N coordinated heterojunction, enabling efficient electron transfer for photocatalytic CO 2 reduction to CO/CH 4 .
