Abstract
Hydrogen storage in metal-organic frameworks (MOFs) is an important and hot topic in hydrogen economics. Unfortunately, no one virgin MOF material can meet the requirement of the U.S. Department of Energy (DOE) by now. Thus, many strategies for enhancing hydrogen uptake have been proposed. Recently, both experimental and theoretical researches indicate that H 2 adsorption capacities of MOFs could be enhanced via doping alkali metal cations to the frameworks, particularly Li +, owing to the strong affinity of Li + for H 2 molecules. Here, we synthesize Li•Cu 3(BTC) 2, and Li•MIL-101 (Cr) by using lithium naphthalenide and further investigate the H 2 sorption capacities of these materials. It is found that at 77 K and 1 bar, the H 2 uptakes of Cu 3(BTC) 2 and MIL-101 (Cr) are increased by 45% and 43%, respectively, after doping lithium, which indicates that the lithium doping does provide an effective approach for enhancing H 2 uptakes.
