纳米Bi_2O_3微粒的固相合成及其电化学性能的研究

Solid-phase Synthesis of Nanophase Bi_2O_3 and Its Electrochemical Properties

用室温和低温固相反应法,采用两种反应途径合成了纳米Bi_2O_3微粒,并用XRD,TEM,CV及恒流充放实验对其性能进行了研究.

Nanophase Bi2O3 was synthesized by two methods, treatment of Bi(NO3)3·5H2O with NaOHin solid-state and decomposition of Bi complex prepared by reacting solid Bi(NO3)3·5H2O with 8-OH-quinoline. The crystal form, particle-size , morphology and electrochemical performance of nanophase Bi2O3 were examined with XRD, TEM, CV techniques and charge-discharge experiment. The results indicated that nanophase Bi2O3 exhibited higher electrochemical activities than common-sized Bi2O3.
