摘　　要：研究了以HCl酸洗、H_2O_2、浓H_2SO_4、HNO_3氧化处理后的活性炭为载体,用不同方法制备了Pt担载量为3%的担载型Pt/C催化剂。TEM统计结果表明,HCl酸洗、HNO_3氧化活性炭为载体,甲醛还原法制备的催化剂分散度最高,平均粒径最小为2．2nm。FT-IR结果表明,HNO_3氧化处理活性炭,活性炭表面含氧基团明显增加。Different methods to prepare Pt/C catalyst were investigated. TEM results showed that the diameter of Pt particle prepared by HCHO reduction method is 2.2nm, which is much smaller than other methods. FF - IR results show that oxidation groups on active carbon were increase by HNO3 oxidation method.
