We request 8 days on IRIS to study the diffusion of adsorbed H2 gas and C2-hydrocarbons molecules within a gated indium-based porous metal-organic framework (MOF) as a function of gas loading and temperature. The proposed study will enable the nature of the diffusion of the gas molecules to be identified, which is of particular interest owing to the hysteretic H2 and hydrocarbons uptake controlled by a gate molecule that is exhibited by this In-MOF. Furthermore the data obtained from the QENS study will enable the activation energy of the diffusion to be quantified and the geometry of the binding sites to be determined.
