| Abstract |
Nowadays, the increasing level of CO2 concentration from the use of fossil fuels has become the most serious environmental concern related to global warming and climate change. The electrochemical CO2 reduction reaction (CO2RR) is a key reaction for CO2 conversion to valuable fuels and chemicals. In this work, we report a low-cost high-efficiency catalyst, zinc oxide (ZnO) nanoparticles, synthesized by sol-gel methods using various precursors. They exhibit 80 % Faradic efficiency of CO2 reduction to CO at -1.0 V versus RHE. In order to understand the remarkable catalytic efficiency, the electronic structures were thoroughly investigated using synchrotron X-ray photoelectron spectroscopy and extended X-ray absorption fine structures, in combination with various electrochemical analyses. |
