摘　　要：通过扩大H型反应器,利用面积超过100 cm 2的铟金属片和锡金属片电极电催化还原二氧化碳制甲酸。从二氧化碳还原反应产物的选择性、电解能力等方面进行了研究,得到了大尺寸金属电极反应器电催化制甲酸的优化方法。结果表明,进气流量40 mL/min和电流密度-3.0~-4.5 mA/cm^(2)区间及中性电解质为反应的最佳条件。By enlarging the H-type reactor,formic acid is produced by electrocatalytic reduction of carbon dioxide using indium metal sheet and tin metal sheet electrodes with an area of more than 100 cm 2.The selectivity of carbon dioxide reduction reaction products,electrolysis ability and other aspects were studied,and the optimization method of electrocatalytic formic acid production in large-scale metal electrode reactor was obtained.The results show that the optimal conditions for the reaction are the air inlet flow rate of 40 mL/min,the current density of-3.0 to-4.5 mA/cm 2,and the neutral electrolyte.
