通过PCT(Pressure-Content-Temperature)设备研究了催化剂CeCl3和Ce(SO4)2对NaAlH4可逆储氢性能的影响.结果显示试样总放氢量随着CeCl3和Ce(SO4)2含量的增加呈先增加后降低的趋势.在第一放氢阶段,掺杂4 mol％ CeCl3试样的放氢速率和放氢量都优于掺杂3 mol％ Ce(SO4)2的试样.在110,130,150和180℃条件下,试样的放氢速率和放氢量随着温度的升高明显升高.
The effects of CeCl3 and Ce(SO4)2 doping on the hydrogen-release capacity of NaAlH4 have been studied by pressure-composition-temperature equipment.The results show that the total amount and the rate of hydrogen release first increase and then decrease with increasing of CeCl3 and Ce(SO4)2 contents.The rate and the amount of decomposition for the sample doped with 4 mol％ CeCl3 in the first-stage dehydrogenation processes are both better than those for the sample doped with 3 mol％ Ce(SO4)2.The rate and the amount of decomposition at 110,130,150 and 180 ℃ present an obvious increase with increasing of temperature.
