Abstract
Abstract Methanol is a highly desirable product of CO 2 electroreduction due to its wide array of industrial applications. However, the development of CO 2 -to-methanol electrocatalysts with high performance is still challenging. Here we report an operationally simple in situ dual doping strategy to construct efficient CO 2 -to-methanol electrocatalysts. In particular, when using Ag,S-Cu 2 O/Cu as electrocatalyst, the methanol Faradaic efficiency (FE) could reach 67.4% with a current density as high as 122.7 mA cm −2 in an H-type cell using 1-butyl-3-methylimidazolium tetrafluoroborate/H 2 O as the electrolyte, while the current density was below 50 mA cm −2 when the FE was greater than 50% over the reported…
