摘要 采用浓硝酸回流法对碳纳米管进行预处理,然后以其为载体在微波辐射加热的条件下合成了Pt/CNTs催化剂,并对其进行了EDX、TEM和XRD表征。对样品的电化学表征结果表明,改性碳纳米管负载的贵金属铂催化剂对甲醇电氧化具有较好的电催化性能。 Carbon nanotubes （CNTs） were firstly pretreated by refluxing in concentrated nitric acid solutions. Then Pt/CNTs catalyst was synthesized by microwave irradiation using this modified CNTs. The product was char- acterized by EDX, TEM and XRD. The electrochemical measurements demonstrated that modified CNTs supported Pt catalyst show better catalytic acitivity for methano electro-oxidation.
