Electrodeposition of Active Platinum on Stainless Steel

采用低毒、较缓和条件下预处理不锈钢基底 ,在电沉积过程中引入超声波振荡技术 ,并筛选出最佳电流密度组合进行电沉积 ,制备出与基底粘结牢固、析氢电催化性能高的不锈钢镀铂电极。从电极的双层电容值可推出电极活性的改善主要归因于表面粗糙度的增加。The substrate of stainless steel was pretreated under low toxic and moderate conditions. Ultrasonic agitation technology was employed in the process of electodeposition. In addition, the optimal combination of current densities was selected. As a result, platinum plated stainless steel electrode which not only was adherent to the substrate but also possessed excellent electrocatalyticproperty for HER was prepared. It can be deduced from the measured values of the double layer capacity of the electrode that the improvement of the electrode activity was mainly due to the increase in surface roughness of the electrode.厦门大学固体表面物理化学国家重点实验室资助!课题 ( 950 1
