Catalytic doping of magnesium hydride (MgH2) to improve its hydrogen ab/desorption kinetic properties is considered be an effective and feasible method. In solid-phase catalysis, the extent contact between catalyst substrate determines catalytic reaction in a great sense. With large specific surface area abundant active sites, two-dimensional (2D) nanomaterials are promising catalysts for MgH2 via providing numerous pathways diffusion dissociation hydrogen. this regard, 2D NiMn-based layered double hydroxide metallic oxide (LMO) designed introduced into storage properties. Simultaneous enhancement interfacial contact, desorption temperature kinetics achieved. The MgH2+9wt% Ni3Mn-LMO composites begin discharge at only 190 °C 6.10wt% H2 could charged 600 s 150 °C. activation energy de/hydrogenation reduced by 42.43 % 46.56 %, respectively, compared pure MgH2. Even low operating 235 °C, modified system was still able release 4.44wt% hour, which has rarely been reported previous studies. Microstructure observations density functional theory calculations revealed that first, pumping effect Mg2Ni/Mg2NiH4 promotes adsorption molecules on MgH2, second, MnOx drew electrons from Mg2Ni, producing new Density State structure with lower d-bond center. This unique change further strengthens pump Our work indicates application metal-based approach towards solid-state meet technical scientific requirements.
