摘要
选用水(溶液)/TritonX-100/环己烷/正己醇的反相胶束体系,制备出棒状和球形两种形貌的纳米Bi2O3前驱体,根据产物的X粉晶衍射谱图和最终的生成条件分析表明该产物为碱式硝酸铋,并从W0(水和表面活性剂的摩尔比)、反应物的浓度和表面活性剂的浓度等因素对合成产物的形貌和尺寸的影响进行了研究.
Club-like and sphericity nanosized precursor of Bi_2O_3 was synthesized in quaternary w/o microemulsion system containing water, triton x-100, cyclohexane and n-hexanol.According to the XRD patterns and relative action conditions,the product can be concluded as bismuth subnitrate.Three key variables—molar ratio of water to surfactant,reactant concentration in water and surfactant concentration in oil phase were investigated to reveal the shape and size changing of nanosized precursor of Bi_2O_3 under different conditions.
