Hydrogen Storage Properies Of Carbon Mesopore Loading LiAIH₄

The experimental and theoretical researches of hydrogen storage in carbon nanotubes(CNTs) since 1997 was never stop,more and more materials were found of ability in hydrogen storage, one of the most important was LiAlH4 which has the 7.6wt% Hydrogen capacitaly,and the news of Carbon mesopore materials have enough micropore volume to adsorb hydrogen were report rencently.This paper want found a way of compose the two methods of hydrogen storage which suffering their own fault both,Carbon need high temperature,but Metal want more active。At first we product CMK-3 with models of SBA-15 which have different hole diameters。The CMK-3-x were marked by the models compose temperature .,We use XRD, SEM ,TEM, and Nitrogen adsorbtion to test them.Then we use the Rubotherm to test the hydrogen adsorbtion ability of them.for different temperature,different pressure different time and times。We have enough data to start the following step。Take determinate CMK-3 and LiAlH4 power dissolution in the enough THF liquid protect by Nitrogen。mixing and circumfluence for about 24 hours then dry it,Test it with Rubotherm indifferent compose temperature,pressure,time and times too。In the end we found it in determinate temperature and pressure the complex hydrogen capacitily lift ,though it not enough to make it possibility in industry,it means the future of this method would be luck。...
