摘    要:用固相反应法制备了Pt/C催化剂(Pt/C(s)),并研究了该催化剂对乙醇氧化的电催化活性. XRD和TEM测量表明, Pt/C(s)中Pt的平均粒径为3.8 nm,结晶度为2.38,远小于用传统的液相还原方法制得的Pt/C催化剂(Pt/C(l))的平均粒径(8.5 nm)和结晶度(5.56).因此, Pt/C(s)对乙醇的电催化氧化性能远好于液相还原法制得的Pt/C(l).

关 键 词:固相反应  乙醇  燃料电池  Pt/C催化剂

Abstract:The Pt/C catalyst (Pt/C(s)) was prepared with solid phase reaction method and its electrocatalytic activity for the ethanol oxidation was studied. XRD and TEM measurements indicated that the average diameter and the crystalline extent of Pt particles in Pt/C(s) are 3. 8 nm and 2. 38, respectively, which are much lower than the average diameter(8. 5 nm) and the crystalline extent(5. 56) of the Pt/C(1) catalyst prepared with the traditional liquid phase reaction method(Pt/C(1)). Therefore, the electrocatalytic activity of Pt/C(s) for the ethanol oxidation is much better than that of Pt/C(1). Cyclic voltammograms and chronoamperometric curves both confirmed this conclusion.
Keywords:Solid phase reaction  Ethanol  Fuel cell  Pt/C catalyst
