Product Overview 

Single-atom catalysts are a class of catalysts in which isolated single atoms are uniformly dispersed on the carrier and without any form of interaction between each individual atom. The active metals in single-atom catalysts are uniformly dispersed on the carrier in the form of single atoms, forming a unique coordination environment with the surrounding atoms. Common single-atom species of single-atom catalysts are precious metals such as Pt, Pd, Au, Ir, Ag and Rh and non-precious metals such as Fe, Co, Ni and Cu. Commonly used carriers are metals and metal oxides, such as Fe2O3, TiO2 and Al2O3, as well as carbon-based carriers, such as carbon nanospheres, nanocarbon fibers, graphene, metal-organic frame-derived carbon, covalent triazine frame, carbon nitride and phthalocyanine-derived carbon. The preparation methods include high-temperature pyrolysis method, impregnation method, atomic layer deposition method, metal-organic frame derivative method and electrochemical deposition method. The single atom catalyst provided by XFNANO uses the pyrolysis of nitrogen-containing carbon organic matter (such as PVP) at high temperature to obtain the amorphous nitrogen-doped carbon carrier, and the metal atoms take nitrate or chloride as the precursor.

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.
