| 제목 | Monovalent Ion Enhanced CO2 Electro-reduction to HCOO- via Porous Bi Catalyst |
| 초록 | Electrochemical conversion of CO2 into value-added chemical products is one of promising strategies for sustainable development. Here we synthesized multiple-layered porous bismuth electrodes using H2 assisted electro-plating process within 5 seconds to convert CO2 into HCOO-. To investigate role of the monovalent ion ( Li+, K+, Cs+, Cl-, Br-, I-) on CO2 electro-reduction, various electrolytes were used while CO2 electro-reduction. And it turns out that Cs+ (or K+), Cl- ions synergistically increase efficiency of CO2 conversion at both low potential region and high potential region. While Li+, Br-, I- ions lower the whole CO2 conversion process. This research was supported by the Basic Science Research Program (2019R1A2C2002602), he Basic Science Research Program (2018R1A6A1A03024962) and the Technology Development Program to Solve Climate Changes (2019M1A2A2065616) through the National Research Foundation, Korea. |
