| 摘 要： | 以多壁碳纳米管(MWNTs)为载体,采用化学还原法制备了多壁碳纳米管负载的铂-二氧化钌纳米颗粒催化剂(Pt-RuO2/MWNTs),并利用透射电镜(TEM)、电化学法等技术对该催化剂形貌和电化学性质进行了表征。结果表明,大小约为4～5nm的金属纳米颗粒均匀地分散在碳纳米管上,同时考察了该催化剂在铁氰化钾溶液中的循环伏安行为以及对该催化剂进行了电化学阻抗分析。

| Abstract: | Pt-RuO2 nanoparticles catalyst supported on MWCNTs were successfully prepared by an organic colloidal process.TEM and electrochemical techniques were employed to characterize the morphology and electrochemical properties of the catalyst.The results showed that the Pt-RuO2 nanoparticles with an average diameter of about 4~5 nm and intensive size distribution were supported on MWNTs.The cyclic voltammetry behavior of the catalyst was also studied in the potassium ferricyanide solution,and the electrochemical impedance of the catalyst was also analyzed. |
