(b) Hydrogen adsorption isotherms for Pd-free and Pd-modified ACF (2.55 wt% Pd). The dashed line represents the amount of hydrogen required to convert the entire Pd content to palladium hydride (β-PdH0.66). (c) HRTEM micrograph of Pd-modified activated carbon fibers. Some degree of ordering is observable within the carbon microstructure.
