Chinese Academy of Sciences develops reductive amination catalyst

Recently, a team of researcher Wang Guanghui from the Qingdao Institute of Bioenergy and Processes of the Chinese Academy of Sciences has developed a new type of NiCx catalyst with carbon doping and controllable particle size

Primary amines and imines are important organic chemical raw materials, which have a wide range of application values ​​in the production of synthetic resins and plastics, adsorbents, dyes, fragrances, drugs and cosmetics

In order to solve the above problems, the research team used polymer spheres as reducing agent, carbon source and size control agent to first grow a hydrotalcite-like precursor on the surface of the polymer in situ, and then use the method of self-reduction by roasting in an inert atmosphere to realize NiCx.

In addition, NiAl-10 and NiAl-5 catalysts exhibited excellent catalytic stability due to the formation of NiCx on the catalyst surface, and the selectivity of both primary amines and imines was consistently greater than 99% during cycling
