Pt/SPE电极的制备及其电化学性能
摘要:
采用SEM、EDS和电化学方法研究了渗透法和浸渍法制备工艺对Pt/SPE电极的表面形貌、组成的影响,并考察了苯甲醇在Pt/SPE电极上的电化学氧化性能.结果表明,浸渍法可以有效降低电极的载Pt量,增加Pt的分散度,电极的真实表面积,并降低电化学反应的表观活化能.浸渍法制备的Pt/SPE电极对苯甲醇电氧化反应有较好的电化学活性.

Preparation and Electrochemical Properties of Pt/SPE Electrodes
Abstract:
The effects of the penetration and impregnation reduction preparation methods on the morphology and composition of Pt/SPE electrode were studied by means of SEM, EDS and electrochemical methods.The electrochemical oxidation properties of benzyl alcohol on the prepared Pt/SPE electrodes were investigated.The results showed that by using the impregnation reduction method, the loading and particle sizes of Pt on SPE membrane were reduced, thus the real surface area of Pt/SPE electrode and the specific activity energy could be increased and improved.
