The Study of Adsorption of Hydrogen on Zeolites

Microporous zeolites as media for hydrogen storage have been paid more and more attention in recent years. However, the reports on hydrogen adsorption mechanism, hydrogen storage capacity of the materials and its relevant factors are quite controversial. In this review, the results of adsorption experiments as well as theoretical modeling for hydrogen storage of various structure-type zeolites are briefly reviewed. The influence of many factors on hydrogen storage capacity is emphatically analyzed, such as the zeolitic structures, Si/Al ratio, type of cations in zeolites and the difference of adsorption experimental conditions, etc. And the progress of supercritical adsorption theory models also is discussed. Finally, the possibility and the research trend of zeolites for hydrogen storage are discussed. Contents
