Abstract

The invention relates to the technical field of catalyst preparation, in particular to a monatomic catalyst and application thereof. The monatomic catalyst is a nitrogen-doped carbon skeleton loaded with metal atoms, wherein the metal atoms comprise at least five of chromium atoms, manganese atoms, iron atoms, cobalt atoms, nickel atoms, copper atoms, zinc atoms and cadmium atoms; a nitrogen-dopedcarbon skeleton is composed of carbon atoms and nitrogen atoms. The at least five monatomic sites are disorderly distributed on the MOF-derived nitrogen-doped carbon skeleton, so that the disorder degree of the system is increased, and the entropy of the system is increased From the perspective of thermodynamics, the high-entropy monatomic catalyst provided by the invention is more beneficial toimproving the overall structural stability of the system.

Description

technical field

[0001] The invention relates to the technical field of catalyst preparation, in particular to a single-atom catalyst and its application. Background technique

[0002] Metal single-atom catalysts refer to catalysts in which metals are uniformly dispersed on the support at the atomic level and have excellent catalytic performance. Due to the characteristics of high atom utilization, highly unsaturated metal site coordination, and strong interaction between the metal site and the support, metal single-atom catalysts usually exhibit ultra-high catalytic activity and selectivity, and have become the current scientific research. One of the important research hotspots in the world and industry.

[0003] Metal-organic framework (MOF) materials provide a powerful synthetic platform for the preparation of metal single-atom catalysts due to their intrinsic physical and chemical properties such as the ordered distribution of metal nodes and the well-defined coordinatio...
