| 摘 要： | 以水溶性离聚物聚（苯乙烯磺酸钠-co-丙烯酸）（PSA）接枝多壁碳纳米管为模板,制备了碳纳米管担载纳米银（AgNP@MWNT）,研究了在碱性条件下对甲醇氧化的电催化作用。结果表明接枝在MWNT表面的离聚物PSA有效地控制了AgNP在MWNT表面以2～4nm的尺寸均匀担载,促进了AgNP与MWNT之间的界面相互作用。制备的Ag@MWNT在水中能够稳定地均匀分散,在碱性条件下可有效地电催化甲醇氧化,抗甲醇中毒性能良好。 |

| Abstract: | Silver nanoparticles loaded on multi-walled carbon nanotubes(AgNP@MWNT) had been successfully prepared with water-soluble poly(sodium 4-styrenesulfonate-co-acrylic acid)(PSA) grafted MWNT as template,and their electrocatalytic effect on oxidation of methanol was studied in alkaline state.Due to PSA grafted on MWNT,the AgNPs were uniformly loaded on the surface of MWNT with size of 2-4nm,and the interface between AgNP and MWNT was enhanced greatly.Additionally,AgNP@MWNT had good dispersivity in water,good el... |
