    Recently, Wang Feng, a researcher at Dalian Institute of Chemical Physics, Chinese Academy of Sciences, has made new progress in the study of acid-base catalysis at the interface of cerium dioxide It is found that there is an interface Lewis acid base pair composed of oxygen vacancy and interface oxygen (ru-o-ce) at the interface of partially oxidized ruthenium cluster and cerium dioxide It is confirmed that the interface oxygen is the springboard for hydrogen transfer and provides suitable protons Thus, low carbon molecules such as ethylene, methanol and Co are used as raw materials under the condition of no acid addition, In one step, new C-C and C-O bonds were formed by efficient catalytic conversion, and methyl propionate, an important oxygen-containing compound, was prepared Acid base catalysis plays an important role in the research of fossil resource utilization and biomass conversion Wang Feng's team is dedicated to the study of oxide structural modification and its catalytic mechanism, especially the study of the catalytic properties of oxide acid-base It was found that the intrinsic oxygen vacancy of cerium dioxide can be used as a water-resistant Lewis acid center to catalyze the preparation of diols from propylene (J am Chem SOC., 2013, 135, 150 doi: 10.1021/ja310498c) in addition to the intrinsic oxygen vacancy, the introduction of doped oxygen vacancy can continue to improve the catalytic performance and expand the application scope of the system (ACS catalyst., 2016, 6, 8248; ACS catalyst., 2018, 8, 2635) Study on the catalytic activity of PR doped cerium dioxide (source: ACS catalyst, DOI: 10.1021 / ja310498c) for the preparation of diol (source: j.am Chem SOC., DOI: 10.1021 / acscan al 6b02134) catalyzed by heterogeneous cerium dioxide, Doi: 10.1021/acscalal.7b04500) related research results were published in J am Chem SOC (DOI: 10.1021/jacs.8b01742) The research was supported by NSFC and the strategic leading science and technology program of Chinese Academy of Sciences Corresponding author: researcher Wang Feng
