Dynamic hydrogen bubbling templated AgSn@SnOx electrocatalyst for selective electrochemical CO2 reduction: adjusting the binding energy of the HCOO* intermediate

Abstract

Core–shell AgSn@SnOx electrodes prepared via dynamic hydrogen bubbling templating and galvanic replacement demonstrated selective electrocatalytic reduction of CO2 towards HCOOH with a faradaic efficiency of 96 ± 4.9% and partial current density of −10.46 ± 0.35 mA cm−2. DFT calculations revealed that the catalyst expedites the production of formic acid via adjusting the binding energy of the HCOO* intermediate.
