Synthesis, Morphology, and Application of New Compound with Srilankite-like Structure and Solid Solution Nanoparticles

研究了工艺参数对材料性能的影响。G.采用水热合成技术，研究了水热处理温度、溶液pH值和前驱体材料对亚稳态和新型纳米化合物如类斯里兰卡石（α-PbO_2相关）、锐钛矿型和金红石型结构的形成、性质和形貌的影响。对它们的新化合物和亚稳化合物的相稳定性、结构和性质进行了估计。介绍了纳米材料在功能材料、电子材料等方面的应用。G.光催化剂和光致发光材料也进行了研究。

T he effect of processing parameters, e. g. hydrothermal treatment temperature, pH of the solution, and precursor materials on the formation, properties, and morphology of metastable and new nano-sized compounds such as srilankite-like(α-PbO_2 related), anatase-type, and rutile-type structure was investigated using hydrothermal synthesis techniques. The phase stability, structure, and characteristics of their new and metastable compounds were estimated. The applications of their nanostructured materials to the functional materials, e. g. photocatalyst and photoluminescent materials were also investigated.
