In-situ synthesis of Cu nanoparticles hybridized with carbon quantum dots as a broad spectrum photocatalyst for improvement of photocatalytic H2 evolution

Exploration of broad spectrum photocatalyst for photocatalytic reaction is of great importance. Cu nanoparticles (NPs) were used for photocatalytic hydrogen evolution due to its surface plasmon resonance (SPR) effect and broad spectrum response. Here, Cu NPs were modified with carbon quantum dots (CQDs) for further improvement of photocatalytic ability. Cu/CQDs composites were prepared by facile in-situ photoreduction and a much higher H2...
