Hydrogen adsorption properties of two different high surface area carbon materials of templated carbon (TC) and superactivated carbon (AX-21) doped with three different metals (Ru, Pt, and Ni) have been studied. The equilibrium hydrogen storage capacities followed the order of Ru/C > Pt/C > Ni/C on both TC and AX-21. Ru doped on templated carbon (Ru/TC) showed a hydrogen storage capacity of 1.43 wt % at 298 K and 10.3 MPa. Furthermore, a thermal reduction method was applied to increase the contacts between the Ru metal particles and the carbon support, and in turn, to facilitate hydrogen spillover. The ruthenium-doped templated carbon by thermal reduction (Ru/TC-T) showed the highest hydrogen storage of 1.56 wt % at 298 K and 10.3 MPa, resulting in an enhancement factor of 2 compared with that of the undoped carbon. These experimental results were interpreted by using a simple mechanistic model for hydrogen spillover.
