MOF-Transformed In2O3-x@C Nanocorn Electrocatalyst for Efficient CO2 Reduction to HCOOH
文献摘要：
For electrochemical CO2 reduction to HCOOH,an ongoing challenge is to design energy efficient electrocatalysts that can deliver a high HCOOH current density(JHCOOH)at a low overpotential.Indium oxide is good HCOOH production catalyst but with low con-ductivity.In this work,we report a unique corn design of In2O3-x@C nanocatalyst,wherein In2O3-x nanocube as the fine grains dispersed uni-formly on the carbon nanorod cob,resulting in the enhanced conduc-tivity.Excellent performance is achieved with 84％Faradaic efficiency(FE)and 11 mA cm-2 JHCOOH at a low potential of-0.4 V versus RHE.At the current density of 100 mA cm-2,the applied potential remained stable for more than 120 h with the FE above 90％.Density functional theory calculations reveal that the abundant oxygen vacancy in In2O3-x has exposed more In3+sites with activated electroactivity,which facilitates the formation of HCOO* intermediate.Operando X-ray absorp-tion spectroscopy also confirms In3+as the active site and the key intermediate of HCOO* during the process of CO2 reduction to HCOOH.
