A team of researchers has developed a cascade catalyst consisting of SnS2 nanosheets and monoatomic Sn to generate formic acid intermediates by carbon dioxide reduction on SnS2 nanosheets and bicarbonate intermediates on monoatomic Sn sites and in situ C-C coupling to generate ethanol. The results show that the selectivity of ethanol can be more than 70% in a wide potential range from -0.6 to -1.1 VRHE, and the mechanism of carbon dioxide reduction C-C coupling on single-atom Sn active centers has been elucidated in combination with isotope labeling experiments and density flooding theory studies.
