[BMPyrr][NTf_(2)]ionic liquid functionalized Au/Pd heterostructure with charge redistribution as effective electrocatalyst for CO_(2)reductionOA
Electrocatalytic CO_(2)reduction reaction(CO_(2)RR)into value-added products has been regarded as an effective way to achieve the goal of carbon neutrality.The intrinsic activity of electrocatalysts,as well as the reaction microenvironment,play an important role in improving the conversion efficiency of CO_(2).Herein,we report an ionic liquidfunctionalized Au/Pd heterostructure as the electrocatalyst for CO_(2)RR via introducing 1-butyl-1-methylpyrrolidine bis(trifluoromethylsulfonyl)imide([BMPyrr][NTf_(2)])ionic liquid.Au nanoclusters are epitaxially confined on Pd nanosheets in heterostructure,resulting in abundant and well-defined heterointerfaces that work as highly active catalytic sites.Notably,the[BMPyrr][NTf_(2)]achieves charge redistribution at the Au-Pd heterointerfaces,which helps to stabilize*CO_(2)^(˙-)intermediate and further reduce the energy barrier of *COOH formation.Furthermore,the[BMPyrr][NTf_(2)]molecules with high CO_(2)adsorption ability is beneficial to construct a CO_(2)-rich reaction microenvironment at the gas-liquid-solid three-phase interface.The hybrid electrocatalyst exhibits greatly improved CO Faradaic efficiency in a broad potential range and CO partial current density.This work provides a novel strategy for designing robust CO_(2)RR electrocatalysts via ionic liquid-mediated surface modification.
