摘要
研究了用固相反应法制备的碳载Pt(Pt/C(s) )催化剂对甲酸氧化的电催化活性 .XRD和TEM的测量表明 ,Pt/C(s)催化剂中Pt的平均粒径和结晶度远小于用传统的液相反应法制备的碳载Pt(Pt/C(l) )催化剂 ,因此 ,Pt/C(s)催化剂对甲酸氧化的电催化活性远高于Pt/C(l)催化剂 .
In this paper, the electrocatalytic activity of the Pt/C catalyst prepared with solid phase reaction method (Pt/C(s)) was investigated for the oxidation of formic acid. XRD and TEM measurements indicated that the average diameter and the crystalline extent of Pt particles in Pt/C(s) catalyst are much lower than that of the Pt/C catalyst prepared with the traditional liquid phase reaction method(Pt/C(l)). Therefore, the electrocatalytic activity of Pt/C(s) catalyst for the oxidation of formic acid is much better than that of Pt/C(l) catalyst.
