不同形貌银的制备及其电催化二氧化碳还原性能
Preparation of Silver with Different Morphologies and its Electrocatalytic Carbon Dioxide Reduction Performance
摘要
Abstract
This paper synthesized three silver catalysts with different sizes and microstructures through precise control methods:silver nanoflowers(Ag NFs),silver nanospheres(Ag NSs),and silver micro flowers(Ag MFs).The composition and microstructure of the three types of silver catalysts were characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS),and physical adsorption testing methods.The electrocatalytic CO2 reduction test results show that Ag NFs have the highest CO selectivity,the highest Faraday efficiency for CO(FECO)can reach up to 88%at a potential of-0.3 V vs.RHE.The good electrocatalytic performance is due to the fact that the wrinkled part of the NFs structure can provide more active sites,and the nano size is conducive to mass and electron transfer.关键词
