| 요약 | The anticipated negative impacts of climate change have prompted efforts to remove excess CO2 from the atmosphere, as well as prevent it from reaching the atmosphere in the first place. Following capture from point emissions sources or directly from the air, CO2 can be transformed into a diverse portfolio of carbon-containing products with both societal and economic value. Electrochemical reduction is an attractive means of converting CO2 into these products, but catalysts capable of facilitating this chemistry are plagued by large energetic requirements, poor selectivities, or limited product distributions. Of all pure-metal electrodes, only copper generates a wide distribution of highly reduced, multi-carbon products, but initial reports of bimetallic catalysts indicate the possibility of unlocking copper-like catalytic behavior using alloys.In this work, bimetallic alloy, intermetallic, and oxide species combining non-CO2 reducing transition metals and Group 13 metals are studied for their electrocatalytic activity toward CO2, emphasizing three different areas of development: (1) catalyst discovery, (2) catalyst tuning, and (3) mechanistic evaluation. Two new electrocatalysts are shown to produce multi-carbon chemicals from CO2 and serve as formative case studies in higher-order product generation. Namely, a CrCO2/O3/Ga2/2 |
