| 摘 要： | 报道了一类壳聚糖预修饰的多壁碳纳米管(MWCNTs)在温和条件下自发还原Cu离子制备Cu修饰碳纳米管基复合材料的新合成路线.联合谱学表征(XRD,SEM,HRTEM,UV-vis)研究表明,平均粒径约为2nm的超小Cu粒子均匀地分散在MWCNTs的表面;氨水是引发自发还原反应的关键因素;Cu修饰碳纳米管基复合材料能高效催化还原对硝基苯酚.

| Abstract: | The novel synthesis of Cu nanoparticles(NPs) decorated multiwalled carbon nanotubes(MWCNTs) via the spontaneous reduction of Cu ions with chitosan(CHIT) functionalized MWCNTs in the presence of amonia has been developed.Characterization of the nanocomposites revealed that the ultrasmall Cu particles(approx.2-3 nm) were well loaded on the surface of MWCNTs.The addition of amonia to the suspension(or dispersed solution) to adjust the pH is responsible for the reduction of Cu ions.The Cu-CHIT-MWCNTs nanocompos... |
