Electrochemical CO 2 reduction provides a desirable pathway to convert greenhouse gas into useful chemicals. It is a great challenge to reduce CO 2 efficiently in aqueous solution, especially on commercial bulk metal electrodes. Here, we report substantial improvement in CO 2 reduction on bulk silver electrode through the introduction of ionic surfactant in aqueous electrolyte. The hydrogen evolution on the electrode surface is greatly suppressed by the surfactant, while the catalytic ability of silver towards CO 2 reduction is maintained. The ...
