【摘要】 采用液相共沉积方法,在常温常压下制备了纳米碘化银铜固溶体粉体。利用透射电子显微镜和X-射线衍射仪分析和观察了该纳米粉体的晶体结构、相结构和微观形貌。结果表明:纳米碘化银铜粉体的晶体结构为β-相,无明显团聚;随铜掺入量的增加,粉体粒径尺寸减少,晶格参数逐渐接近冰晶的晶格参数。更多还原

【Abstract】 Nano-silver-copper iodide powders have been prepared by using the method of liquid-phase deposition at normal temperature and pressure.Lattice structure,phase structure and micro-morphologies of the nano-powders were characterized and observed by using the transmission electron microscopy and X-ray diffraction.It was demonstrated that the nano-silver-copper iodide powders have the lattice structure of β-phase,do not show evident agglomeration;as the amount of copper doping increases,the average grain size reduces,the lattice constants become small and are gradually close to those of ice crystal.The nano-powders are expected to become a high effective and relatively lower-cost catalyser agent applied to weather modification.更多还原
