英文摘要 | Electroreduction of carbon dioxide to hydrocarbons has been proposed as a promising way to utilize CO2 and maintain carbon balance in the environment. Copper (Cu) is an effective electrocatalyst for such a purpose. However, the overall selectivity towards hydrocarbons on Cu-based electrodes is still very limited. In this work, we develop a general amino acid modification approach on Cu electrodes for the selective electroreduction of CO2 towards hydrocarbons. A remarkable enhancement in hydrocarbon generation is achieved on these modified copper electrodes, regardless of the morphology of the Cu electrodes. A density functional theory calculation reveals that the key intermediate CHO star is stabilized by interacting with -NH3+ of the adsorbed zwitterionic glycine. Our results suggest that amino acids and their derivatives are promising modifiers in improving the selectivity of hydrocarbons in CO2 electroreduction.; National Research Foundation (NRF), Prime Minister's Office, Singapore, under its Campus for Research Excellence and Technological Enterprise (CREATE) programme; Ministry of Education, Singapore [M4011253 RG 7/14, M4020246, ARC10/15]; SCI(E); EI; ARTICLE; WangXin@ntu.edu.sg; 5; 1687-1695; 9 |
