Abstract

N- and S-doped C-encapsulated CeO2 with a hinge-like nanostructure (CeO2@N,S–C HN) has been obtained by using a Ce-based metal–organic framework (Ce-MOF-808) as a precursor. Due to the synergistic effects of its special structure and N,S-doped C layer, CeO2@N,S–C HN exhibits high activity of photocatalytic hydrogen (H2) evolution. Density functional calculations are used to obtain a fundamental understanding of the high H2 production rate of CeO2@N,S–C HN.
