In view of problems of low-yield two-electron oxygen reduction reaction (2e ORR) for H2O2 evolution and sluggish anodic half reaction, the O2 evolution reaction (OER), whose product O2 is not of significant value. This project start with explore the 2e ORR matched organic selective oxidation reaction (OSOR). OSOR, a thermodynamically more favorable reaction, the oxidation of biomass intermediates to value-added chemical, assist by H2O2 (the product of 2e ORR). The design of Ferrite Series Metallic and Metallic Interstitial Compound act as the basic catalyst, change coordination structure and the electronic structure by controllable O-Doped. .Combining the modern characterization, electrochemical technique and theoretical calculation, how will the O-Doped of the catalyst effect the catalytic activity and selectivity of 2e ORR and OSOR are in-depth studied. Reveal the relationship between the structure of catalyst and process of 2e ORR and OSOR.An 2eORR-OSOR H-type electrochemical reaction system was constructed，promote the performance of the cell with 2e ORR and OSOR, explore how does the H2O2 (the production of 2e ORR) assists OSOR. It provides experimental and theoretical foundation for the construction of high efficiency electrochemical system.
