The structure and catalytic mechanism of metal oxide surface active sites in synthesis gas conversion revealed by Dalian Institute of Chemical Technology

Recently, Bao Xinhe, academician of the Chinese Academy of Sciences, researcher of the Carbon-based Energy Nanomaterials Research Group of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and researcher Pan Xiulian's team have made progress in the regulation mechanism of the synthesis gas conversion OXZEO reaction activity, revealing the bifunctional catalyst metal oxide surface coordination Activation and transformation of carbon monoxide/hydrogen (CO/H ₂ ) by unsaturated metal sites and the regulation of the pathw.

Focusing on the catalytic mechanism of OXZEO, researchers have reached a consensus that the surface defect structure of metal oxides plays an important role in the activation of CO/H2, but there is still a lack of knowledge about the types of defect structures and their mechanism of _action

Bao Xinhe and Pan Xiulian's team proposed the design concept of a nanocomposite bifunctional OXZEO catalyst coupled with metal oxides and molecular sieves in 2016, and realized the highly selective generation of light olefins C ₂ =-C ₄ = (Science, 201

The related research results were recently published in Nature Communications under the title Steering the Reaction Pathway of Syngas-to-light Olefins with Coordination Unsaturated Sites of ZnGaO _x Spine.
