1SDS-modified Nanoporous Silver as an Efficient Electrocatalyst for Selectively Converting CO2 to CO in Aqueous Solution显示文摘Selectively electrochemical conversion of CO2 into organic fuel using renewable electricity is one of the most sought-after processes.In this paper,we report the electrochemical reduction of CO2(CO2RR)on the nanoporous Ag electrodes made of compacted Ag nanoparticles(AgNPs),which were prepared by one-step reduction in the water phase with or without the surfactant sodium dodecyl sulfate(SDS).The scanning electron microscope(SEM)characterizations show that the compacted Ag electrodes have the nanoporous morphology formed by stacking AgNPs.Compared with the nanoporous Ag electrode without SDS modification(C-AgNPs),the SDS-modified AgNPs electrode(C-AgNPs-SDS)is highly effective in improving selective CO production in a wide range of potentials(-0.69 V--1.19 V,vs.RHE),with a Faradaic efficiency of 92.2% and a current density of -8.23 mA·cm^-2 for CO production at -0.79 V(vs.RHE).C-AgNPs-SDS is also catalytically stable with only less than 7% deactivation after 8 h of continuous electrolysis.Lei Shi Yuning Zhang Xiaofei Han Dongfang Niu Jinlong Sun Jenny Y.Yang Shuozhen Hu Xinsheng Zhang 2019Chinese Journal of Chemistry2019,37,4:5
