摘要
Hydrogen storage is critical to realize the so-called hydrogen economy in which fuel cells vehicle(FCV)is the engine room.The most recently commercialized FCVs such as Mirai(Toyota,Japan)and Clarity(Honda,Japan)use the high pressure hydrogen gases(70Mpa)as hydrogen storage.The capacity of hydrogen can reach a weight percentage of 5.7%,which exceeds the Department of Energy(Do E)of USA in 2017.However,this method of hydrogen storage still have some concerns,e.g.the safety issue and the energy consumption when presses the gas.Solid hydrogen storage materials can overcome the above disadvantages.However,they suffer from either thermodynamically unstable(physisorption by highly porous materials)or too stable(chemisorption by hydrides).In one word,the materials cannot satisfy the requirement of operational temperature,which is in a range of-30~85 °C according to Do E.In view of this critical challenge,a nano confinement strategy,confined the chemical hydrogen materials inside highly porous materials,was applied.This strategy aims to alter the thermodynamics of hydrogen storage materials inside the pores of porous materials by the size and interfacial effect,thus reduce the high temperature to an appropriate temperature for the hydrogen release in stable chemical compounds.Here,we will present the hydrogen storage behavior of various chemical compounds including Mg H_2,Li BH_4,Mg(BH_4)2 and H3NBH3 confined by different porous materials including carbon,SBA-15,MOFs and COFs.
