中文摘要：

[摘要]以仲钼酸铵为前驱物，采用溶胶一凝胶法和氢气还原工艺制备了碳纳米管／Mo复合粉末材料．采用扫描电子显微镜（SEM）和x射线衍射（XRD）分析了微观形貌和相态组成．结果表明：在750℃还原保温3h可制备出碳纳米管／Mo复合粉末，还原生成的Mo粉颗粒在碳纳米管周围聚集，使碳纳米管在Mo粉中均匀分散；高于800℃还原，碳纳米管与Mo反应生成M02C相；而低于750℃还原，则有MoO2相残存．

英文摘要：

Abstract： Ammonium paramolybdate as a precursor, carbon nanotubes （CNTs） / Mo composite powders were prepared by sol-gel method followed by hydrogen reduction process. Scanning electron microscopy （SEM） and X-ray diffraction （XRD） were used to analyze the micrograph and phase composition. Results show that CNTs/Mo powders can be synthesized by hydrogen-reduction at 750℃ for 3h. CNTs are uniformly distributed between Mo powders because of the reduced Mo particles aggregating around the surface of CNTs. When the reduction temperature is a above 800%, MOEC is formed as the reaction of CNTs and Mo. However, when the reduction temperature is below 750℃, MoO2 phase is found in powders.
