在氢气保护下,采用机械合金化制备4MgH2/TiHz以及4MgH2/TiH2 +5％A(质量分数,A=AlCl3,LaCl3,CeCl3)复合材料,并通过PCT、XRD、SEM以及DTA等手段对复合材料进行表征.结果显示,4MgH2/TiH2以及4MgH2/TiH2+5A(A=AlCl3,LaCl3,CeCl3)复合材料吸氢量均在4.5％(质量分数)左右,且在150 s时间内吸氢即可达到饱和.添加CeCl3后,复合材料的脱氢反应焓从添加前的72.7 kJ/mol下降到65.1 kJ/mol,而添加MCl3和LaCl3后,复合材料的脱氢反应焓则分别增加到80.6 kJ/mol和82.5 kJ/mol.这表明CeCl3能有效提高4MgH2/TiH2复合材料的热力学性能,而AlCl3和LaCl3的添加则会导致4MgH2/TiH2复合材料的热力学性能下降.
