The Front Cover shows multi‐layered porous dendrite Bi electrocatalysts synthesized through hydrogen bubble‐assisted electrodeposition. They exhibit a faradaic efficiency (FE) of approximately 100% in the conversion of CO₂ to formate. The added CsCl significantly enhances the steady‐state partial current density for formate production. A photovoltaic cell‐assisted electrocatalysis produces formate with an FE of approximately 95% at 10 mA cm⁻² at an overall solar conversion efficiency of approximately 8.5 %. The Bi electrodes maintain their activity over 360 h without a change in the surface states. More information can be found in the Full Paper by G. Piao, S.‐H. Yoon, et al.

在多孔树突状铋电极上以高效率和持久性将离子从CO2转化为甲酸的离子增强

前封面显示了通过氢气泡辅助电沉积合成的多层多孔枝状晶体Bi电催化剂。它们在将CO ₂转化为甲酸酯时表现出约100％的法拉第效率。添加的CsCl可以显着提高甲酸生产的稳态部分电流密度。光伏电池辅助的电催化在10 mA cm ^-2时产生的甲酸酯的FE约为95％，总太阳能转化效率约为8.5％。Bi电极在360小时内保持其活性，而表面状态没有变化。有关更多信息，请参见S.‐H的G. Piao撰写的全文。Yoon等。
