摘　　要：以硝酸铈和硝酸锌为金属氧化物前驱体,聚乙烯吡咯烷酮为碳前驱体,N,N-二甲基甲酰胺为溶剂,采用静电纺丝技术,在500℃氮气环境下煅烧2 h,合成了一维氧化铈-氧化锌/碳纳米纤维。详细阐述了氧化铈-氧化锌/碳纳米纤维的结构、形貌和组成。氧化铈-氧化锌/碳纳米纤维的直径约为400 nm,比表面积为215.89 m^(2)/g,孔体积为0.019 cm^(3)/g。通过电化学测试,研究了氧化铈-氧化锌/碳纳米纤维在碱性溶液中的电化学性能。表明氧化铈-氧化锌/碳纳米纤维在储能器件中具有潜在的应用前景。One dimensional CeO_(2)-ZnO/CNFs were facilely synthesized via electrospinning technique employing cerium nitrate and zinc nitrate as the metal oxide precursors,poly(vinylpyrrolidone)as the carbon precursor,N,N-dimethylformamide as the solvent,followed by calcination at 500℃for 2 h under N 2 atmosphere.The characterizations,including structure,morphology,and composition of CeO_(2)-ZnO/CNFs were demonstrated in detail.The diameter of the nanofiber was about 400 nm.The specific surface area was 215.89 m^(2)/g,and the pore volume was 0.019 cm^(3)/g.Moreover,the electrochemical behaviors of CeO_(2)-ZnO/CNFs were investigated using cyclic voltammetry in alkaline aqueous electrolyte.This work indicates a potential application of CeO_(2)-ZnO/CNFs in energy storage devices.
