Product Overview 

Monatomic catalysts are a class of catalysts in which isolated individual atoms are uniformly dispersed on a carrier without any form of interaction between each individual atom. The active metal in a monatomic catalyst is uniformly dispersed as individual atoms on a carrier, forming a unique coordination environment with the surrounding atoms. Common types of monoatomic catalysts with single atoms include noble metals such as Pt, Pd, Au, Ir, Ag, Rh and non-precious metals such as Fe, Co, Ni, Cu. Commonly used carriers are metals and metal oxides, such as Fe2O3, TiO2 and Al2O3, and carbon-based carriers, such as carbon nanospheres, carbon nanofibres, graphene, metal-organic framework-derived carbon, covalent triazine frameworks, carbon nitride, and phthalocyanine-derived carbon. Preparation methods include high-temperature pyrolysis, impregnation, atomic layer deposition, metal-organic framework derived and electrochemical deposition. The single-atom catalysts provided by Xianfeng are obtained by high-temperature pyrolysis of nitrogen-containing carbon organics (e.g., PVP) to obtain amorphous nitrogen-doped carbon carriers, with the metal atoms using nitrates or chlorides as precursors.

Product Features

High activity: Due to the high dispersion of metal atoms on the carrier, each metal atom can become an active centre, thus increasing the activity of the catalyst. 

High selectivity: the regulation of reaction selectivity can be achieved by controlling the coordination environment of the metal atoms and the nature of the carrier. 

High stability: the strong interaction between the metal atoms and the carrier can improve the stability of the catalyst. 

Application Fields

Energy: Single-atom catalysts can be used to improve the efficiency of the oxygen reduction reaction in fuel cells, thereby enhancing the performance of the cells. It can also be used in electrolysis of water to produce hydrogen to effectively promote hydrogen precipitation reaction, reduce the reaction overpotential, and improve the efficiency of hydrogen production. 

Environmental protection: monatomic catalysts can be used to degrade organic pollutants. In wastewater treatment, iron monatomic catalysts can be used to catalyse the degradation of organic pollutants such as phenols and dyes.

Chemical production: monatomic catalysts help to achieve the hydroconversion of nitrogen under mild conditions and improve the reaction rate and selectivity of ammonia synthesis. 

Petrochemicals: monatomic catalysts can effectively remove sulphur compounds from petroleum products and reduce the sulphur content of oil. 

Fine Chemicals: Metal monatomic catalysts can catalyse specific organic reactions for the synthesis of drug molecules, improving reaction selectivity and yield.
