花状二氧化锡分级结构的可控合成
|
摘要
采用水热法,不选用任何模板剂与生长基底,以Na_2SnO_3·4H_2O为前驱体,乙醇和水的混合溶液为溶剂,合成了花状SnO_2分级结构;研究了前驱液锡源浓度和表面活性剂对花状SnO_2分级结构和形貌的影响.
A novel structure of flower-like SnO_2 hierarchical structure was synthesized by facile hydrothermal route only using Na_2SnO_3·4 H_2O and alcohol-water,using neither surfactants nor substrates. The dependence and influence of the flower-like SnO_2 hierarchical structure on the precursor solution treatment,surfactants and et al were investigated.
