Investigating zeolites as hydrogen storage scaffolds is imperative due to their porous nature and favorable physicochemical properties. Nevertheless

the storage capacity of the unmodified zeolites has been rather unsatisfactory (0.224%-1.082% (mass)) compared to its modified counterpart. Thus

the contemporary focus on enhancing hydrogen storage capacities has led to significant attention towards the utilization of modified zeolites

with studies exploring surface modifications through physical and chemical treatments

as well as the integration of various active metals. The enhanced hydrogen storage properties of zeolites are attributed to the presence of aluminosilicates from alkaline and alkaline-earth metals

resulting in increased storage capacity through interactions with the charge density of these aluminosilicates. Therefore

there is a great demand to critically review their role such as well-defined topology

pore structure

good thermal stability

and tunable hydrophilicity in enhanced hydrogen storage. This article aimed to critically review the recent research findings based on modified zeolite performance for enhanced hydrogen storage. Some of the factors affecting the hydrogen storage capacities of zeolites that can affect the rate of reaction and the stability of the adsorbent

like pressure

structure

and morphology were studied

and examined. Then

future perspectives

recommendations

and directions for modified zeolites were discussed.
