Defect-rich N-doped CeO2 supported by N-doped graphene as a metal-free plasmonic hydrogen evolution photocatalyst

We reported a plasmonic photocatalyst consisting of N-CeO₂ supported by N-graphene for light-driven HER, which offered a superior performance relative to N-CeO₂ and CeO₂ catalysts. This could be due to the plasmonic effects of N-CeO₂ and excellent conductivity of N-graphene.
