- Abstract
Carbon quantum dots-titanium dioxide composite (CQDs-TiO) has been synthesized by a simple hydrothermal process. It was used as a heterogeneous catalyst for oxidation of alcohols using water as a solvent. The morphologies and composition of the resulting catalysts were characterized to show that the CQDs were uniformly dispersed on the surface of the TiO with well combination with each other. The obtained catalyst showed enhanced catalytic activities compared to the pure CQDs catalyst. The enhanced catalytic activities were mainly attributed to the highly dispersive CQDs with more active centers which caused by the TiO support. The CQDs-TiO catalyst can also be reused without any significant loss in their catalytic activities after five times. Graphical Abstract:
