硼掺杂碳化硅负载pt催化剂的甲醇电催化氧化性能
, PP. 845-850
Keywords: 甲醇电氧化,硼掺杂碳化硅,pt催化剂
Abstract:
？以硼掺杂碳化硅（b0.1sic）为载体，采用循环伏安法在b0.1sic载体上电沉积pt纳米粒子制备了pt/b0.1sic催化剂。利用x射线光电子能谱、x射线衍射、氮气吸附-脱附、扫描电镜及透射电镜等测试方法对催化剂的晶型、表面性质及形貌进行了表征。结果表明，硼原子掺杂进入sic晶格并取代了si位点，使b0.1sic载体的导电性增强；pt纳米粒子均匀地分布在b0.1sic载体上，平均粒径为2.7nm。与相同条件下制备的pt/sic催化剂相比，pt/b0.1sic具有较大的电化学活性表面积、更高的甲醇催化氧化活性和稳定性。
