摘要：

A novel semiconductor-metal-graphene stack design, which reduces interfacial defect density as well as provides channels for charge transport, has been demonstrated to harness the charge flow for efficient electron-hole separation. As a direct outcome, the designed hybrid structures exhibit significantly improved performance in photocatalytic hydrogen production from water.
