摘要： 本文采用机械球磨法制备了(NaH/Al)+x(摩尔分数, %)Ti(x=0, 4, 6, 10)复合物, 研究了不同球磨气氛和Ti催化剂含量对其微结构和储氢性能的影响, 使球磨(NaH/Al)体系储氢的容量达到质量分数为4.01%.

关键词: 络合氢化物, 储氢性能, 机械球磨, NaAlH4, Ti

Abstract: In this paper, the microstructure and hydrogen storage properties of the (NaH/Al)+x(molar fraction, %) Ti(x=0, 4, 6, 10) composites were investigated. It was found that the reversible hydrogen storage properties can be improved by mechanically ball-milling the(NaH/Al) mixture together with Ti powder.

Key words: Complex hydrides, Hydrogen storage properties, Mechanically ball-milling, NaAlH4, Ti
