摘要：负载金属Pd和PdO都有助于提高超高比表面积活性炭的吸氢性能,并能使其吸氢能力分别提高2倍～4倍和4倍～5倍左右.同时由于过渡金属在高温下容易发生团聚和迁移现象,负载在活性炭上的金属Pd的还原温度和还原时间应分别控制在125℃和2h.在0℃和27℃常压下,Pd/AC和PdO/AC(SBET为3886m2/g)对氢的饱和吸附量分别为:20mL/g、23mL/g和14mL/g、15.8mL/g,且它们的循环使用寿命良好.
The hydrogen adsorption capacities of Pd and PdO supported high surface area activated carbons (HSACs) are respectively 2 - 3 and 4 - 5 times higher than pure HSACs. The reduction temperature and time for Pd HSACs, should be controlled at 125 degrees C for 2h, because metal particles of Pd dispersed of the surface of the activated carbon will agglomerate or move out of the pores of activated carbon at higher temperatures and longer times. Pd/HSACs and PdO/HSACs had high hydrogen saturated-adsorplion capacity of 20 and 23 mL/g respectively at room temperature and ambient pressure, and 14 and 15.8 ml g respectively at 0 degrees C and ambient pressure. They exhibit mild adsorption/ desorption conditions for hydrogen and it good adsorption -desorption cycle property.
