金纳米颗粒/活性炭纤维的绿色制备及性能表征

Green Preparation and Characterization of Gold Nanoparticles Loaded on Active Carbon Fiber

采用绿原酸为绿色还原剂,在活性炭纤维(Active Fiber Carbon,ACF)上还原金前驱体形成金纳米颗粒(Gold nanoparticles,Au NPs),制备出Au NPs/ACF纳米复合材料,采用透射电子显微镜(TEM)、扫描电子显微镜(SEM)、比表面及孔径分析仪对其形貌和比表面积进行了表征。结果表明该绿色还原法可以同时制备Au NPs并进行在ACF上的负载,避免了毒性较大的还原剂硼氢化钠的使用,具有较高的环境友好性。

The nano-composite material of gold nanoparticles loaded on active carbon fiber(Au NPs/ACF) was prepared using chlorogenic acid as a green reductant. The Au NPs/ACF was characterized by transmission electron microscope(TEM), scanning electron microscope(SEM), and specific surface analyzer. Our results show that Au NPs were prepared, as well as loaded on the ACF by this green reduction method, which is environmentally friendly without using stimulating chemical reagents.
