Invited speaker 10: Dehui Deng, Dalian Institute of Chemical Physics, China | New processes for low-temperature conversion of C1 molecules (INV 10)

Efficient conversion and utilization of C1 molecules is of great strategic significance to alleviate the energy crisis and achieve the goal of carbon neutrality. However, in industry, C1 molecules are mostly carried out under high temperature, high pressure, and other harsh reaction conditions. The efficient conversion of small energy molecules under mild conditions has always been a technical bottleneck. It is urgent to seek new catalytic processes and conversion approaches. Therefore, major innovations in catalytic materials, catalytic processes and catalytic concepts are needed. The reporter has long been committed to the research on the surface and interface regulation of two-dimensional catalytic materials, and has carried out in-depth research on the major scientific problems and challenges in the conversion of C1 molecules: 1) Proposed and enriched “Chainmail catalysis” concept, which provides a new way for the rational design of highly stable catalysts under harsh conditions. 2) For the first time, achieved direct catalytic conversion of methane at room temperature by using graphene-confined single iron center as a catalyst. 3) For the first time, achieved high-efficiency, long-life catalytic hydrogenation of carbon dioxide to methanol at low temperature by using sulfur vacancy-rich two-dimensional MoS₂ as a catalyst. The reporter will focus on the new processes of low-temperature catalytic conversion of C1 molecules, as well as the key scientific issues and application prospects in combination with the research progress of the reporter’s group in recent years on the surface and interface regulation of two-dimensional catalytic materials and the conversion of small energy molecules.
