 CUSAC6N6 is a novel copper-based single-atom catalyst that has the ability to perform both basic oxidation and gain reactions. This catalyst is able to overcome the limitations of other catalysts due to its unique topological structure and specialized donor acceptor linker. The catalyst's ability to switch between different reaction pathways allows it to have high stability and efficiency when performing either reaction. Additionally, the catalyst is able to be used in a variety of applications, from biosensors to chemical synthesis. This article was authored by Ching Hong, Hong Yang, Yang Feng Fang, and others.
