| Abstract |
The rising atmospheric concentrations of greenhouse gases, especially CO₂, are among the most pressing social issues today. The electrochemical CO₂ reduction reaction (CO₂RR) is a key reaction for CO₂ conversion to valuable fuels and chemicals. Metals, such as Cu, Ag, Au, and Zn, are typical catalysts to reduce electrochemically CO₂ to the molecules in aqueous electrolytes, Development of low-cost high-performance catalysts is very crucial for the commercialization of CO₂RR technologies. Here, we report a low-cost high-efficiency catalyst, iridium oxide -zinc oxide (IrO2-ZnO) hybrid nanoparticles, which exhibit 80 % Faradaic efficiency of CO2 reduction to CO at -1.0 V versus RHE. In order to understand the remarkable catalytic efficiency of IrO2-ZnO, the electronic structures were thoroughly investigated using synchrotron X-ray photoelectron spectroscopy in combination with various electrochemical analyses. |
