Highly Efficient CO2 Utilization via Molten Salt CO2 Capture and Electrochemical Transformation Technology |
| |
| Abstract: | The molten electrolytes exhibit high CO2 absorption capacities, wide electrochemical windows and excellent reaction kinetics, which are promising electrolyte candidates for efficient capture and electrochemical conversion of high-flux CO2 driven by renewable and clean electricity sources. This short review introduces the recent advancements of CO2 electroreduction achieved by the authors using molten salt CO2 capture and electrochemical transformation (MSCC-ET) technology, involving CO2 absorption kinetics, cathodic kinetics, controllable synthesis of carbon products with unique nanostructures, development of inert oxygen evolution anodes and CO2 conversion efficiency as well as energy efficiency. The challenges and prospects are also discussed based on the critical review. |
