摘要
旨在寻找和研制电还原顺丁烯二酸制备丁二酸中高活性、高选择性的电极材料,采用自行研制的不锈钢(Stainlesssteel,SS)载表面合金电催化材料(Surface alloy/SS)作为工作电极,利用CV研究了其在常温常压、不同电流密度和支持电解质等条件下顺丁烯二酸电合成丁二酸中的性能,通过离子色谱电导检测等技术对电合成产物进行检测分析.结果表明:Surface alloy/SS电极对顺丁烯二酸的加氢还原表现出很高的电催化活性;对产物丁二酸的选择性高;优化的电解条件为:电流密度27.68 mA·cm-2,0.1 mol·L-1硫酸作为支持电解质.
In this work,we hope to search and prepare high activity and good selectivity cathode materials for the electroreduction of cis-Butenedioic acid to Butanedioic aicd.The electrocatalysts of surface alloy supported glassy carbon (GC) were prepared by electrochemical co-deposition method.And the properties of these electrocatalyts for the electroreduction of cis-Butenedioic acid to Butanedioic aicd on different conditions were studied through cyclic voltammetry(CV).The reduction electrolyte was analyzed by Ion chromatography(IC) with conductivity detector.The results demonstrated that the surface alloy/SS exhibited a high electrocatalytic activity towards cis-Butenedioic acid reduction.The main reduction product identified by IC was Butenedioic acid,indicating that the Surface alloy/SS electrode exhibited also an excellent selectivity for Butanedioic acid in cis-Butenedioic acid reduction.The optimized electrolysis conditions were identified as:the current density was 27.68 mA·cm^(-2) and supporting electrolyte was 0.1 mol·L^(-1) H_2SO_4.
