Abstract

Promoting the separation of photo-generated carriers is significantly important to improve the efficiency of photocatalytic hydrogen production. Therefore, we prepared g-C N /CeCO OH/CeO (CeCeCN) ternary nanocomposite via an easy synthetic way using g-C N and CeO as reactants. A CeCO OH layer was formed and resulted in the novel ternary photocatalyst. The CeCeCN composite shows superior photocatalytic (PC) H generation performance in sunlight excitation. The H evolution rate is about 764 μmol h g , which is over 11 times larger than those of g-C N and CeO . Compared with g-C N and CeO , CeCeCN further shows a larger photo-response current density and a lower charge-transfer resistance. The remarkably increased photocatalytic property of CeCeCN is because of the efficient charge migration induced by the formed heterojunction. Our findings demonstrate that building multi-heterostructures can liberate more excited electrons for efficient hydrogen production under sunlight.
