ABSTRACT
N-GO assisted S-scheme CeO2/g-C3N4 catalyst is prepared. The unique S-scheme and the presence of IEF at the interfaces of CeO2 and g-C3N4 maximize the redox ability of photogenerated carriers and the unique Ce4+ →Ce3+ conversion property promotes the charge carrier transfer efficiency, resulting in the outstanding degradation activity.

ABSTRACT
A novel 0D/2D Cu2CoSnS4/ZnIn2S4 p-n heterojunction photocatalyst is developed to efficiently generate H2 from water splitting under visible-light irradiation. The internal electric field at Cu2CoSnS4/ZnIn2S4 interface promotes the separation of photogene-rated charges and enables the accumulation of valence band electrons in ZnIn2S4 for fast water reduction reaction.
