| description | The electrochemical carbon dioxide reduction reaction (CO<sub>2</sub>RR) to C<sub>2</sub> chemicals has received great attention. Here, we report the cuprous oxide (Cu<sub>2</sub>O) nanocubes cooperated with silver (Ag) nanoparticles via the replacement reaction for a synergetic CO<sub>2</sub>RR. The Cu<sub>2</sub>O-Ag tandem catalyst exhibits an impressive Faradaic efficiency (FE) of 72.85% for C<sub>2</sub> products with a partial current density of 243.32 mA·cm<sup>−2</sup>. The electrochemical experiments and density functional theory (DFT) calculations reveal that the introduction of Ag improves the intermediate CO concentration on the catalyst surface and meanwhile reduces the C-C coupling reaction barrier energy, which is favorable for the synthesis of C<sub>2</sub> products. |
