钌酸铅纳米晶的合成

Synthesis and Characterization of Nanocrystals Pb 2Ru 2O 6 5

以己酸钌、辛酸铅和己酸为原料合成Ｐｂ２Ｒｕ２Ｏ６．５纳米晶，平均粒度为４０ｎｍ，烧成温度为６００℃，低于传统的合成温度。用红外光谱、差热分析、Ｘ射线衍射对合成过程进行了研究，用透射电镜考察纳米晶的粒度和形貌，用ＢＥＴ吸附法测定纳米晶的比表面积。合成的纳米晶Ｐｂ２Ｒｕ２Ｏ６．５纯度高，粒度小且较均匀，在常温下属立方晶烧绿石结构。

Nanocrystals, Pb 2Ru 2O 6 5 , with average size of 40nm were synthesized by using lead n-octate, ruthenium hexate, and hexoic acid as raw materials at the temperature of 600℃. The nanocrystaline Pb 2Ru 2O 6 5 samples were characterized by transmission electron microscope, DTA-TG, IR, X-ray diffraction, and BET.
