More Information
Summary:The invention discloses preparation and application of an iron-based nitrogen-doped carbonaceous material with carbonic anhydrase-like activity, the material Fe10 (at) CN-Mg is prepared by adopting a coprecipitation method and a high-temperature carbonization method, and most of iron substances are uniformly distributed on nitrogen-doped carbon in a monatomic form; wherein the synergistic catalysis effect of the FeNx active site and the Mg (OH) 2 nanorod has carbonic anhydrase-like activity. The material has relatively low metal content and low preparation cost, but still has a dynamic constant comparable with that of other reported CA-like nano-enzymes and an excellent CaCO3 formation rate, shows excellent stability even under extreme pH, high temperature, organic solvents and high ionic strength, and can be applied to the preparation of the nano-enzyme. The catalyst can still keep high activity after being stored for a long time and recycled for multiple times, and can be applied to catalysis of conversion
