摘　　要：以NaOH和Bi(NO_3)_3·5H_2O为原料,并添加不同的分散剂,采用室温固相法制备了纳米Bi_2O_3采用XRD、TEM表征纳米Bi_2O_3的结构和形貌。结果表明,分散剂种类、分散剂的添加量等因素显著影响纳米Bi_2O_3结构和形貌。Nanometer Bi2O3 was synthesized from NaOH and Bi(NO3)3 ·5H2O with different surfactants added at room-temperature by solid-station reaction,and was characterized by XRD and TEM.The result shows that the structure of nanometer Bi2O3 heavily depends on the types and amounts of surfactants added.
