Pd在超级活性炭上的负载对其储氢性能的影响

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℃ for 2h, because metal particles of Pd dispersed on 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-adsorption capacity of 20 and 23 mL/g respectively at room temperature and ambient pressure, and 14 and 15.8mL/g respectively at 0℃ and ambient pressure. They exhibit mild adsorption/desorption conditions for hydrogen and a good adsorption-desorption cycle property.
