摘要
在室温或近室温条件和超声波作用下,通过固相化学反应合成出了金属氧化物、金属硫化物、金属草酸盐、金属碳酸盐、金属钼酸盐等五类纳米材料.用粉末X射线衍射(XRD)、透射电镜(TEM)和电子衍射法对其物相、晶粒形貌和晶粒大小进行了表征.结果表明,用该方法合成纳米材料具有产率高、不需要溶剂、反应时间短、室温或近室温反应和纳米材料稳定性好等显著优点.
Nanocrystalline oxide series, sulfide series, oxalate series, carbonate series, molybdate series were synthesized at (or near) ambient temperature by solid state chemical reaction. Phases, particle sizes and morphology of the prepared nanocrystallite were characterized by powder X-ray diffraction (XRD) and transmission electron microscopy (TEM). The results show that the strking advantage of the approach are high yields, using no solvents, rapidity of reactions at (or near) room temperature and relative stability of nanoparticles.
