利用静电纺丝和化学镀技术相结合的方法,制备出镀金聚丙烯腈杂化纤维膜Au-PAN,然后以此为载体,再利用化学镀法在该膜的表面镀上一层铂纳米粒子,从而构建出催化电极Pt/Au-PAN.为了比较,在相同条件下将商用Pt/C滴涂到Au-PAN基底上构建催化电极Pt/C/Au-PAN.采用SEM、TEM和XRD对催化电极结构表征,并研究其催化氧化甲醇的性能.结果表明:用化学镀法制备的Pt/Au-PAN电极对甲醇的电化学氧化活性和稳定性都明显优于商用铂碳催化剂.
Electro-spinning and electroless plating techniques were used to prepare gold-plated polyacrylonitrile hybrid fiber membrane Au-PAN, and then use this as a carrier, and then use the electroless plating method in the film surface coated with a layer of platinum nanoparticles (Pt / C / Au-PAN) was deposited on the Au-PAN substrate under the same conditions by using Pt / C as a commercial electrode.Using SEM, TEM and XRD The results showed that the electrochemical oxidation activity and stability of Pt / Au-PAN electrode prepared by electroless plating were obviously better than that of commercial Pt-C catalyst.
