The specific aim is to develop graphene oxides (GOs) and reduced GOs and their hybrids with tunable bandgap and band alignment with respect to the energy levels of CO2 reduction. The ultimate goal is to establish GO-based photocatalysts for CO2 reduction to hydrocarbons under visible light. A series of GO-based hybrids with metals, non-graphene two-dimensional materials such as metal sulfides, and organics sensitizers will be investigated. Theoretical support for the design of materials and the understanding of their surface behaviors with the resultant photocatalytic activity will be conducted.石墨烯有機光敏分子二維半導體光催化二氧化碳還原低碳氫燃料Graphene oxidestwo-dimensional materialsorganic sensitizersphotocatalysisCO2 reduction國際合作研究計畫【低維度碳材料與其奈米複合結構於可見光催化還原二氧化碳之研究】
