"German Applied Chemistry" reports the new progress of Hydrogenation of hydrogen peroxide of Huaji overcover catalyst

Recently, Professor Hua Li Chunzhong has made new progress in the field of single atomic catalyst composite hydrogen peroxide (H2O2). The relevant research results are "Super-CoordinalEd Nickel N4NI1O2SITE SINGLE-ATOM Catalyst for Selectrosynthersis at High Current Dens". In "German Applied Chemistry".

The use of single atomic catalysts to achieve electricity reducing oxygen preparation H2O2 has received widespread attention from scientific researchers, but the report has been reported that there are still lack of current density and large energy consumption. Therefore, how to further regulate the local groups of the single atom catalyst, and build a super -coordinate single atom catalyst that is different from the traditional setting structure, is the key to achieving high selective preparation of H2O2 under industrial -grade current density.

This work is the first to prepare a nickel single atom catalyst (N4NI1O2) with a six -piece structure, and uses the carboxyl -based multi -wall carbon nanopotherapy carrier to provide two O. For NIN4 of the traditional four -setting structure. The results of the performance test show that this ultra -control N4NI1O2 single atom catalyst has extremely high electrical composition H2O2 performance: industrial -grade current density (200 MA CM−2) to prepare H2O2's cathode energy efficiency of more than 82%, and it can stabilize at least 24 hours. Essence Its catalytic performance is better than the highest value of literature, and it is 6 times that of the four -fold NIN4 catalyst performance.

The first author of the work is the doctor of the doctor Chu Chuqian, and the author of the joint communication is Professor Li Chunzhong and Li Yuhang, a young teacher. The research has received funding support from the National Natural Science Foundation of China, Shanghai Science and Technology Innovation Project, and the Scientific Research Innovation Plan Project of Shanghai Education Commission.
