Bridging the plasmonic copper and N-Doped graphitic carbon by embedding conductive honeycomb-like carbon sphere mediators for highly efficient photocatalytic hydrogen evolution

Improving the separation of photogenerated electron–hole pairs is considered an effective approach to enhance the photocatalytic activities. Herein, Cu nanoparticles (NPs) are loaded on N-doped graphitic carbon (NGC)/honeycomb-like carbon sphere (HCS), where HCSs is dispersed on the NGC layer, obtaining a novel NGC/HCS/Cu NPs (GCPC) hierarchical structure for photocatalytic hydrogen evolution under simulated sunlight. The intercalation of HCS as...
