Photocatalytic performance of carbon quantum dots / bismuth phosphate composites 

Abstract：In recent years,the earth faces difficult to avoid the deterioration of the environment and pollution problems,now with the global pollution become more and more intense, photocatalytic technology in the world of purification is more and more concerned by the people. In order to in-depth study and realize the implementation of this technique in a variety of industries in the practical significance,I will aim to explore the applicability and higher photocatalytic materials,and pay efforts to enhance the photocatalytic efficiency. The preparation for high active carbon quantum dot /BiPO4 composite photocatalytic material which is controlled in structure and morphology as research object,through the combination of BiPO4 and carbon point,the photocatalytic efficiency will be further improved,and to a certain extent, the photocatalytic activity of BiPO4 can be promoted. In addition,this design lucubrate the performance of the composite photocatalytic material system, through different schemes include research ideas, provide a feasible research ideas for the future for people to study carbon quantum point /BiPO4 composite light catalytic performance.
