Angew Chem: Nature of the Active Sites of Copper Zinc Catalysts for Carbon Dioxide Electroreduction
The synergistic effect between Cu and Zn enabling optimal adsorption of CO is reported. Through high throughput screening for optimal CO adsorption, two types of active sites were identified that effectively facilitated the C−C coupling, […]
