In situ construction of all-solid-state Z-scheme g-C 3 N 4 /ZnNCN/ZnO with carbodiimide bridges for superior photocatalytic H 2 O 2 production

-based systems reported to date. Furthermore, this architecture endows the catalyst with excellent performance in the photodegradation of rhodamine B (RhB) and tetracycline. By introducing carbodiimide-bridged Z-scheme heterojunctions, this study provides a versatile strategy for designing next-generation photocatalysts for both energy synthesis and pollution control.
