The palladium-salen complex was immobilized by electropolymerization onto a Pt disc electrode and applied as an electrocatalyst for the reduction of CO in an aqueous solution. Linear sweep voltammetry measurements and rotating disk experiments were carried out to study the electrochemical reduction of carbon dioxide. The onset overpotential for carbon dioxide reduction was approximately -0.22 V vs. NHE on the poly-Pd(salen) modified electrode. In addition, by combining the electrochemical study with a kinetic study, the rate-determining step of the electrochemical CO reduction reaction (CORR) was found to be the radial reduction of carbon dioxide to the CO adsorbed on the metal.
通过电聚合将钯-席夫碱配合物固定在铂盘电极上,并用作水溶液中一氧化碳还原的电催化剂。进行线性扫描伏安法测量和旋转圆盘实验以研究二氧化碳的电化学还原。在聚钯(席夫碱)修饰电极上,二氧化碳还原的起始过电位相对于标准氢电极约为-0.22V。此外,通过将电化学研究与动力学研究相结合,发现电化学一氧化碳还原反应(CORR)的速率决定步骤是二氧化碳向吸附在金属上的一氧化碳的径向还原。
