Palladium hollow nanospheres were prepared by the adsorption of metal nanoparticles onto functionalized gamma-Al2O3 templates. The silanizing agent 3-mercaptopropyl trimethoxysilane was reacted with the surface of the gamma-Al2O3 templates to afford thiol-terminal groups. Metal layers of palladium were coated directly on the gamma-Al2O3 templates by increasing the temperature stepwise. Then, the dissolution of the gamma-Al2O3 template using 40 wt% HF solution enabled the formation of self-organized metallic palladium hollow nanospheres. The palladium hollow nanospheres were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray analysis (EDX), X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) techniques.
通过将金属纳米颗粒吸附到功能化的γ-Al2O3模板上来制备钯空心纳米球。硅烷化剂3-巯基丙基三甲氧基硅烷与γ-Al2O3模板表面反应，得到硫醇端基。通过逐步升高温度，将钯金属层直接涂覆在γ-Al2O3模板上。然后，使用40 wt%的HF溶液溶解γ-Al2O3模板，从而形成自组装的金属钯空心纳米球。通过扫描电子显微镜（SEM）、透射电子显微镜（TEM）、能量色散X射线分析（EDX）、X射线衍射（XRD）和傅里叶变换红外光谱（FTIR）技术对钯空心纳米球进行了表征。
