壳聚糖修饰碳纳米管对PdNi/CNTs甲醇氧化性能的影响

Effect of Modified Chitosan on Performance of PdNi/CNTs Electrocatalyst for Methanol Oxidation

以壳聚糖修饰的碳纳米管为载体,用微波辅助法制备Pd Ni/CNTs电催化剂,考察了壳聚糖的引入对Pd Ni在碳纳米管上的分散效果及对电催化性能的影响。结果表明:壳聚糖的加入改善了Pd Ni粒子的分散性,催化剂的电化学面积增大,动力学性能也得到了改进。

PdNi/CNTs electrocatalyst was prepared through the microw ave-assisted synthesis method. Chitosan modified carbon nanotubes was used as supporter. The influences of the addition of chitosan to the dispersion effect of Pd Ni on carbon nanotubes and catalytic performance were investigated. The addition of chitosan improved the distribution of Pd Ni nanoparticles on the carbon nanotubes support and enlarged the electrochemical area. The dynamic performance was also improved.
