Review on Graphene Based Photocatalyst for Carbon Dioxide Reduction

Global warming and lack of energy are two important issues of this century. heating caused by increased carbon dioxide is an important issue that can be addressed through the process of reducing carbon dioxide to produce certain sources of chemicals and fuels. at the same time, the production of carbon-based products through the reduction process can be generated to assist in the generation of useful energy. reduced carbon dioxide by photocatalytic methods is increasingly gaining attention as this method can convert carbon dioxide into hydrocarbon fuels. graphene, a two-dimensional material is now widely used in photocatalytic methods to enhance the ability of the reduction process. high electrical conductivity, wide surface area and high chemical stability make graphene-based photocalisers have their own advantages in reducing carbon dioxide. fabrication of graphene-based materials has been known as one of the most feasible strategy to improve the carbon dioxide reduction performance of photocatalyst. moreover, the combination of graphene with semiconductors provides a facile strategy to enhance their activities and stabilities.this study discusses the features and designs of graphene-based photocatalysts that aid the reduction process and the problems faced by graphene-based photocatalysts are also discussed for future applications. through reviewing the significant advances on this topic, it may provide new opportunities for designing highly efficient graphene-based photocatalysts for carbon dioxide reduction application.
