Co induced Bimetallic Sulfide pn Heterojunctions for Boosted Photoelectrocatalytic Ethylene Glycol Oxidation Reaction
Co induced Bimetallic Sulfide pn Heterojunctions for Boosted Photoelectrocatalytic Ethylene Glycol Oxidation Reaction
研究概述
电沉积构建CoS2/FeS p–n异质结，将乙二醇光电氧化为甲酸。内建电场促进电荷分离，硫桥介导Fe向Co电子转移，并降低吸附乙二醛的反应能垒。1.33 V（相对RHE）下光生电流10 mA/cm²，反应后唯一检测到的液相产物为甲酸。
