| 摘 要： | 在含四氢呋喃(THF)的水溶液中, 室温下用NaBH4还原H2PtCl6和RuCl3制得Pt-Ru/C催化剂. 其Pt-Ru 粒子的合金化程度较高, 平均粒径较小, 相对结晶度较低. 因此对甲醇氧化的电催化活性远高于Pt-Ru 粒子的平均粒径和相对结晶度相似的， 而且Pt-Ru合金化程度低的商业化的E-TEK的Pt-Ru/C催化剂, 表明Pt-Ru的合金化程度对Pt-Ru/C催化甲醇氧化的电催化活性有很大的影响. |

| Abstract: | It was found that the carbon supported Pt-Ru catalyst(Pt-Ru/C) with the Pt-Ru particles with high alloying,small average size and low relative crystallinity can be prepared in the aqueous solution with tetrahydrofuran(THF) using NaBH_(4) as a reductant for reducing H_(2)PtCl_(6) and RuCl_(3) at room temperature.The electrocatalytic activity of the Pt-Ru/C catalyst for the methanol oxidation is much higher than that of the commercial E-TEK Pt-Ru/C catalyst with the similar average size and relative crystallinity,but low alloying.It is(indicated) that the alloying of Pt-Ru could significantly affect the electrocatalytic activity of the Pt-Ru/C catalyst for the methanol oxidation.The Pt-Ru/C catalyst with high alloying can be obtained because THF and H_(2)PtCl_(6) can form the complex leading to that the reduction potentials of H_(2)PtCl_(6) and RuCl_(3) are closed in the aqueous solution with THF. |
| Keywords: | Pt-Ru/C catalyst Tetrahydrofuran Direct methanol fuel cell Alloying |
