Description
Summary:The production of solar fuel through photocatalytic water splitting and CO2 reduction using photocatalysts has attracted considerable attention owing to the global energy shortage and growing environmental problems. During the past few years, many studies have demonstrated that graphene can markedly enhance the efficiency of photocatalysts for solar‐fuel generation because of its unique 2D conjugated structure and electronic properties. Herein we summarize the recent advances in the application of graphene‐based photocatalysts for solar‐fuel production, including CO2 reduction to hydrocarbon fuel and water splitting to H2. A brief overview of the fundamental principles for splitting of water and reduction of CO2 is given. The different roles of graphene in these graphene‐based photocatalysts for improving photocatalytic performance are discussed. Finally, the perspectives on the challenges and opportunities for future research in this promising area are also presented. There’s always the sun: Graphene‐based photocatalysts for solar‐fuel production are of significant interest in solving the global energy problem. The recent advances in the fabrication and application of graphene‐based photocatalysts, including photocatalytic reduction of CO2 to hydrocarbon fuels and photocatalytic splitting of water to H2 are explored.
