The hydrogen absorption properties of two microporous metal organic frameworks (MMOF) at low temperatures was investigated. The MMOFs contain very small pores with pore dimensions in the range of micropores and exhibit similar sorption properties to other porous material characteristic of physisorption. It was found that the MMOFs incorporate metals that are likely to interact with absorbed hydrogen more strongly that other types of sorbents. The results show that the high density of absorbed H2 falls in the range of liquid H2 and suggests relatively strong sorbent interactions in the materials with very small pores.
