Ion-Enhanced Conversion of CO2 into Formate on Porous Dendritic Bismuth Electrodes with High Efficiency and Durability |
| 초록 |
Facile synthesis of efficient electrocatalysts that can selectively convert CO2 to value-added chemicals remains a challenge. Herein, the electrochemical synthesis of porous Bi dendrite electrodes and details of their activity toward CO2 conversion to formate in aqueous solutions of bicarbonate are presented. The as-synthesized multilayered, porous, dendritic Bi electrodes exhibit a faradaic efficiency (FE) of approximately 100% for formate production. Added halides and cations significantly influence the steady-state partial current density for formate production JFM (Cl-＞Br-＞≈I-; Cs+＞K+＞Li+). Photovoltaic-cell-assisted electrocatalysis produced formate with an FE of approximately 95% (JFM≈10 mA cm-2) at an overall solar conversion efficiency of approximately 8.5%. The Bi electrodes maintain their activity for 360 h without a change in the surface states. |
