中文摘要：

理论分析表明，分子尺度纳米空隙结构SiC材料的吸附储氢性能优于相应的C质材料。采用先驱体法制备了SiC纤维，研究了裂解温度、先驱体处理方法对所制备SiC纤维的吸附储氢性能的影响。氢的吸附采用体积法进行测定，结果表明，随裂解温度的升高SiC纤维的吸附量先增加后减少，而后又有所增加。先驱体分别用四氢呋喃（THF）和乙醇浸泡处理后制备的SiC纤维，其室温吸附量比未处理的要大，有的超过了多壁碳纳米管的吸附量。

英文摘要：

Silicon carbide fibers pyrolyzed at different temperatures were synthesized by precursor method. The effects of pyrolysis temperatures and precursor treatment methods on the hydrogen adsorption and storage properties were studied. It was found that with the increase of pyrolysis temperature, the hydrogen adsorption of SiC fibers increased at first, then decreased, but then increased again. The hydrogen adsorption of SiC fibers at room temperature increased when the sol in precursors was removed by tetrahydrofuran （THF） and alcohol dipping, and some values exceeded that of the multi-walled carbon nanotubes.
