Electrocatalytic CO2<\/sub> reduction reaction (CO2RR), using clean electricity to convert CO2<\/sub> and water into chemicals and fuels, is an effective way to simultaneously close the carbon cycle and store renewable energy.<\/p>\n

It’s difficult to generate multicarbon (C2<\/sub>+<\/sup>) products due to the multiple proton-electron transfer, the complex intermedia<\/a>tes and the sluggish C-C coupling step during CO2<\/sub>RR to C2<\/sub>+<\/sup> products, leading to low selectivity and production rate for C2<\/sub>+<\/sup> formation.<\/p>\n

Recently, a research team led by Prof. Wang Guoxiong, Prof. Gao Dunfeng and Prof. Bao Xinhe from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Science<\/a>s (CAS) designed a Cu-CuI composite catalyst, achieving efficient production of C2<\/sub>+<\/sup> chemicals from CO2RR.<\/p>\n

This study was published in Angewandte Chemie International Edition<\/i> on April 10.<\/p>\n

The researchers designed the catalyst with abundant Cu0<\/sub>\/Cu+<\/sub> interfaces by physically mixing Cu nanoparticles and CuI powders.<\/p>\n

Structural characterizations indicated that the Cu-CuI composite catalyst underwent significant reconstruction under CO2RR conditions, which was induced by alkaline electrolyte and app<\/a>lied potential.<\/p>\n

The high-rate C2<\/sub>+<\/sup> production over Cu-CuI was ascribed to the presence of residual Cu+<\/sup> and adsorbed iodine species, which improved CO adsorption and facilitate C-C coupling.<\/p>\n

“This work presents a new strategy for designing efficient catalysts towards high-rate CO2<\/sub>RR to C2<\/sub>+<\/sup> products,” said Prof. Wang.<\/p>\n\n
