Promotion of electrochemical CO2 reduction to ethylene on phosphorus-doped copper nanocrystals with stable Cu delta+ sites
Electrochemical reduction of CO2 to C2+ products is a sustainable energy-driven pursuit for high added-value hydrocarbons. Tremendous efforts have been made to copper based electrocatalysts, which are well-known for producing C2+ products. However, being short of well-defined catalysts with stable Cu delta+ electronic structure hinders its practical application and in-depth understanding. Herein, we developed a facile one-pot approach to prepare Cu delta+ -rich catalyst by doping phosphorus. Enhanced performance and tunable product selectivities are achieved due to the electron donor-acceptor interaction based on phosphorus content in series. C-2 hydrocarbons and alcohols are produced with high (similar to 44.9%) selectivity, in which C2H4 (30.7 +/- 0.9%) is dominant at -1.6 V vs reversible hydrogen electrode (RHE). This P-Cu catalyst shows a significantly higher current density (57.2 mA cm(-2) ) compared to pristine Cu. In addition, the favorable Cu delta+ is reserved during CO2RR contributing to a longterm stability. Experimental results and DFT calculations demonstrate that the Cu delta+ moiety facilitates the adsorption of carbon intermediates, C-C coupling and hence promotes the generation of C2H4 energetically. The well-designed catalyst indicates the profit of electronic structure engineering in designing catalysts for multiplestep chemical conversions.
