电解质种类对AgBi/C催化剂的CO2电催化还原选择性影响

Effect of Electrolyte on the Selectivity of CO2 Electrocatalytic Reduction Over AgBi/C Catalyst

利用简单液相法合成AgBi/C双金属催化剂,并探究其在不同种类的电解质溶液中CO2电催化还原性能。研究表明说明电解质中阴离子种类对CO2电催化还原的选择性有重要影响,在KCl电解质溶液中AgBi/C催化剂上CO2电催化还原产物主要是HCOOH,在KHCO3电解液中,低过电势时还原产物主要为CO。

AgBi/C was synthesized by a simple method and investigated the performance of CO2 electrocatalytic reduction in different electrolyte.The results indicated that the anion in electrolyte had significant influence on the selectivity of CO2 electrocatalytic reduction.The primary product of CO2 electrocatalytic reduction over AgBi/C catalyst wasHCOOH in KCl,while in KHCO3 the main product was CO.
