Molecular Dynamics Simulations of Adsorption in Nanoporous Materials

Molecular dynamics simulations provide atomic-scale insight into the adsorption of gases and vapours within nanoporous hosts by numerically integrating the trajectories of individual molecules under defined interatomic potentials. These methods capture physisorption and chemisorption phenomena in materials such as zeolites, metal–organic frameworks and mesoporous silica, enabling prediction of adsorption isotherms, transport coefficients and energy landscapes. Advances in force-field development and high-performance computing have facilitated systematic studies of pore-size dependence, surface chemistry and confinement effects on thermodynamics and kinetics. By modelling guest–surface interactions, simulations reveal how pore geometry, surface functional groups and defect sites govern uptake capacity, selectivity and diffusion behaviour. Multiscale approaches that couple atomistic simulations with continuum or coarse-grained models bridge nanometre to macroscopic scales, guiding the rational design of adsorbents for gas separation, carbon capture, hydrogen storage and catalysis. The global importance of this field is underscored by pressing energy and environmental challenges, where tailored nanoporous materials offer routes to clean technologies and efficient resource utilisation backed by predictive molecular-level understanding.
