英文摘要Nano-structured beta-Mo2C on ultrahigh surface area carbon material (>3000 m(2)/g) was prepared by carbothermal hydrogen reduction method. The MoO3 precursor and Mo2C have been characterized by X-ray diffraction, nitrogen adsorption, high-resolution transmission electron microscope (HRTEM) and temperature-programmed reduction-mass spectroscopy (TPR-MS). The data show that nanostructured beta-Mo2C can be formed on the ultrahigh surface area carbon materials by carbothermal hydrogen reduction at 700 degreesC. The particle sizes of beta-Mo2C increase with the increase of the temperature of carbothermal hydrogen reduction. The carbothermal hydrogen reduction includes two successive steps: reduction of MoO3 precursor by hydrogen and reaction between partially reduced molybdenum oxides and surface carbon atoms of carbon materials.
