Recently, Research Center for Solar Driven Carbon Neutrality has made significant progress in the controlled preparation of photocatalytic materials and the high-value conversion of carbon dioxide into light olefins, constructing a Co^0-Co^δ+ interface double-site-mediated C-C coupling reaction to promote the photothermal conversion of CO₂ into light olefins. The related work "Co^0-Co^δ+InterfaceDouble-Site-Mediated C—C Coupling for the Photothermal Conversion of CO₂into Light Olefins" was published in Angewandte Chemie International Edition (IF=16.8, DOI: 10.1002/anie.202302253) with Hebei University as the main research institution. Dr. Ning Shangbo is the first author of the paper, and Professor Ye Jinhua, Professor Wang Dingsheng from Tsinghua University, and Dr. Ou Honghui are co-corresponding authors.

Converting carbon dioxide (CO₂) into multi-carbon (C²⁺) products via photothermal catalysis is a promising method to alleviate energy shortages and achieve carbon neutrality. The bottleneck in this reaction is the regulation of the C-C coupling reaction of the C₁ intermediate. This study provides a new idea for the design of photothermal catalysts applied for the conversion of photoreductive CO₂ to C²⁺ hydrocarbons.Experimental and theoretical calculations confirm that the interfacial dual active site achieves effective adsorption and activation of CO₂ to generate C1 intermediates via the Co⁰ site, while the introduction of the electron-deficient state of Co^δ+ effectively reduces the energy barrier of the key CHCH* intermediates. This study provides a new idea to design photothermal catalysts applied for the conversion of photoreductive CO₂ to C²⁺ hydrocarbons.
