| 摘 要： | 利用辐射还原法,在100, 200, 500 kGy辐射剂量下制备了金属Pd掺杂的碳气凝胶粉末。X射线衍射（XRD）,扫描电子显微镜（SEM）和能谱测试证实了辐射法成功地制备出Pd掺杂的碳气凝胶粉末复合物。SEM照片表明,还原生成的金属Pd相对均匀地分布在所有碳气凝胶颗粒表面。N2吸附数据分析表明:掺入金属Pd后，碳气凝胶粉末比表面积、平均孔径和总孔体积都显著减小。由于被还原金属大多沉积在碳气凝胶粉末表面，不同辐射剂量下制得的掺杂碳气凝胶粉末的比表面积等多孔特征数据相差不大。

| Abstract: | Pd-doped carbon aerogel powder is prepared with radiation method in 100, 200 and 500 kGy radiation doses, which has been confirmed by XRD, SEM and energy spectrum test. The SEM images show that Pd is well distributed in all the surface of aerogel particles. The nitrogen adsorption data analysis shows that the specific surface area, average pore diameter and total pore volume of carbon aerogel powder all decrease obviously after Pd doping. As the reduced metal mostly decorates the outer surface of the carbon aerogel powder, the textural parameters of doped carbon aerogel powder in different radiation doses are close to each other. |
