| 摘 要： | 以泡沫镍为基体,应用电化学沉积法制备Pd-Ir/Ni复合催化剂.由SEM、XPS分析样品的表面形态、组成以及各组分的价态.电化学测试表明该催化剂对H2O2电还原具有较高的催化性能,当过氧化氢的浓度为0.4 mol/L时,极限电流密度可超过318 mA/cm2.以纯铝或其合金作阳极、Pd-Ir/Ni作阴极组装Al-H2O2半燃料电池,得出其最大放电功率可达198 mW/cm2.

| Abstract: | The Pd-Ir/Ni electrodes were prepared by electrodeposition of Pd and Ir on the porous nickel foam surface.The structure,composition and state of the Pd-Ir catalyst were analyzed using SEM and XPS.The catalytic performance of Pd-Ir/Ni for H2O2 electroveduction at different concentrations of H2O2 were investigated.A limiting current density of 318 mA/cm2 was obtained with 0.4 mol/L H2O2.The aluminum-hydrogen peroxide semi-fuel cells using different aluminum alloys as anode and Pd-Ir/Ni as cathode were assembl... |
