A series of carbon supported Platinum catalysts with novel crystal structure were developed for hydrogen storage applications. These catalysts trigger a substantial spillover decomposition of hydrogen molecules followed by the physical sorption of hydrogen atoms at the sorption sites between Pt and carbon regions. The corresponding mechanisms were derived by first-principle density functional theory simulation complementary with the in-elastic neutron backscattering, and the X-ray absorption spectroscopes.
