    Recently, the team of Wang Feng, researcher of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, has made new progress in oxide bound free radical catalysis, and relevant articles have been published in the Journal of American Chemical Society (j.am.chem.soc., 2018, DOI: 10.1021/jacs.7b12928) In nature, the free radical is a kind of particularly active group When the free radical combines with oxygen, it will form the active oxygen free radical Therefore, the activation of hydrocarbon bond by the free radical is an important method to realize the selective oxidation of hydrocarbons to generate oxygenated compounds It is a common strategy to convert stable hydrocarbons into carbon radicals first by using nitrogen oxygen radicals However, the initiator is usually needed to produce nitrogen oxygen radicals, and the life of nitrogen oxygen radicals is short (millisecond level), which is easy to cause uncontrolled free radical chain side reactions and autophagy reactions of hydrocarbons Source of oxide bound radical catalysis: J am Chem SOC The team has been working on the selective activation of oxides The latest research has found that metal oxide semiconductors can bind nitrogen oxygen radicals, increase the half-life of nitrogen oxygen radicals from millisecond to second (22 seconds), and maintain a high ability of catalyzing C-H bond selective activation This study provides a new way to control the properties of free radicals and a new way to improve the utilization of hydrocarbon resources by using organic free radicals The above research is supported by the pilot program of the Chinese Academy of Sciences, the National Natural Science Foundation of China and our institute (article / figure Zhang Chaofeng) paper link: https://pubs.acs.org/doi/abs/10.1021/jacs.7b12928 brief introduction of researcher Wang Feng: http://sourcedb.dicp.cas.cn/zw/zjrck/201106/t20110628_.html researcher Wang Feng
