“…The mixed suspension of CQDs and metal NPs can also be stirred by ultrasound to promote their combination. Kaimal et al first prepared Au NPs with surfactant Cetyl-trimethyllammonium bromide, the shape-directing agent KI, the reductant ascorbic acid and the Au precursor HAuCl 4 [59]. Then B-doped CQDs were prepared by hydrothermal method with glucose as the carbon source and boric acid as the boron source.…”

Since metal nanoparticles-carbon quantum dots nanocomposites combine the advantages of both carbon quantum dots and metal nanoparticles, they show unique properties and are applied in heterogeneous catalysis. In the nanocomposite catalysts, CODs can act as modifiers to modulate the electronic properties of the metals or produce synergy with the metals. Consequently, the nanocomposite catalysts have good catalytic performance. This paper summarizes the preparation methods of nanocomposite catalysts and focuses on their applications in heterogeneous catalysis. Various specific preparation methods are not only summarized as completely as possible but also are also classified at the macro logic level. The applications of the nanocomposite catalysts in heterogeneous catalysis include photocatalysis, sonocatalysis, electrocatalysis, and thermal catalysis. It also reveals how the nanocomposite catalysts produce excellent catalytic performances in various catalytic reactions. Finally, the existing problems and the direction of future efforts are proposed. It is hoped that this paper will provide a slight reference for the future research of metal nanoparticles-carbon quantum dots nanocomposite catalysts and their application in the field of catalysis.a:Industrial Catalysis Institute of Zhejiang University of Technology, State Key Laboratory Breeding Base of Green Chemistry Synthesis Technology, Hangzhou, 310032, People’s Republic of China
