超声化学法制备纳米材料

We made the Sonochemical reactor by ourself, designed and selected various kinds of non-oxides system, developed a series of new chemical reaction under sonochemcial irration and successfully synthesized non-oxides nanomaterials, such as metal, metal sulfies, selenides, tellurides, phosphides, and arssenides. Especially the sonochemcial synthesis of III-V group nanomaterials was established at room temperature, which is the first report of the synthesis of III-V group at room temperatures. Also we explored the morphology control of nanomaterials and successfully prepare the nanorods, nanospheres and nano hollow spheres. 11 papers have been published in important intenational journals such as "Adv. Mater.","Chem. Mater." and "Inorg. Chem." These researchs are of signifinance in many aspects such as the exploring new techniques of chemical preparation of nanomaterials and the inverstigation of mechanism of sonochemcial reactions.
