Altered thermodynamic and kinetic properties of MgH2 infiltrated in microporous scaffold

MgH2 nanoparticles with a size of <3 nm were formed by direct hydrogenation of Bu2Mg inside the pores of a carbon scaffold. The activation energy for the dehydrogenation was lowered by 52 kJ mol(-1) compared to the bulk material, and a significantly reduced reaction enthalpy of 63.8 +/- 0.5 kJ mol(-1) and entropy (117.2 +/- 0.8 J mol(-1)) was found for the nanoconfined system.
