| 摘 要： | 利用辐照还原法在500 kGy辐照剂量下制备了Au掺杂MF有机气凝胶。通过X射线衍射（XRD）、能量色散光谱仪（EDX）和透射电子显微镜（TEM）测试证实了辐照法成功地制备出Au掺杂MF有机气凝胶复合物。EDX和TEM照片表明辐照处理后Au纳米颗粒均匀地分布在MF气凝胶骨架中，并且Au纳米颗粒的平均尺寸为5.8 nm。N2吸附数据分析表明掺入Au纳米颗粒后，MF气凝胶的比表面积、总孔体积、微孔体积和介孔体积都有所下降。

| Abstract: | The Au-doped melamine-formaldehyde(MF) aerogel was fabricated by-irradiation of AuCl3solution with MF aerogel monoliths impregnated. The obtained samples were characterized by X-ray diffraction (XRD), energy dispersive spectroscopy (EDX) and transmission electron microscope (TEM). The results show that the well distributed Au nanoparticles presented in MF aerogels and the average particle size was 5.8 nm after irradiation. The nitrogen adsorption characterization reveals the introduction of Au nanoparticles produced a reduction of the surface areas and total, micropore and mesopore volumes. |
