Facet effects on bimetallic ZnSn hydroxide microcrystals for selec.ive electrochemical cO2 reduc.ion

引用

Green Energy & Environment 2024年第8期9卷 1314-1320页

作者： Liu Han cheng-wei Wang Shan-shan Luo Ying-tang Zhou Bing Li Ming Liu School of chemistry and chemical Engineering Harbin Institute of Technology National Engineering Research center for Marine Aquaculture Marine Science and Technology CollegeZhejiang Ocean University

Employing crystal facets to regulate the catalytic properties in electrocatalytic carbon dioxide reduc.ion reac.ion（ecO2RR） has been well demonstrated on electrocatalysts containing single metals but rarely explored for bimetallic systems. Here, we synthesize Zn Sn（OH）6（ZSO）microcrystals（Mcs） with distinct facets and investigate the facet effects in ecO2RR. Electrochemical studies and in situ Fourier Transform infrared Spectroscopy（in situ-FTiR） reveal that ZSO Mcs produce mainly c1 products of HcOOH and cO. The {111} facet of the ZSO McS exhibits higher selec.ivity and faradaic efficiency（FE） than that of the {100} facet over a wide range of potentials（-0.9 V ～-1.3 V versus RHE）. Density Func.ional Theory（DFT） calculations elucidate that the {111} facet is favorable to the adsorption/ac.ivation of cO2molecules,the formation of intermediate in the rate-determining step, and the desorption of c1 products of cO and HcOOH molecules.
