Hydrogen absorption in f.c.c. nanoparticles of 1–8 nm diameter was investigated using molecular dynamics simulation with model interatomic potentials. Atomic configuration with five-fold symmetries was observed in both hydrogen-free and hydrogenated particles smaller than 2 nm. The f.c.c. structure was maintained in larger particles after hydrogenation in cases where the M–H interaction is weak. Lattice deformation was induced in cases of strong M–H interaction. A shift of critical size for icosahedral–cubic transition by hydrogenation was also inferred. The number of absorbed H atoms increased concomitantly with increasing particle size and M–H interaction. Most absorbed H atoms located at O-sites when M–H interaction was weak. The T-site occupancy increased with M–H interaction. Analysis using local atomic configuration revealed that structural variation in nanoparticles results from three factors: surface effects, icosahedral transformation, and lattice deformation attributable to M–H interaction.
