Abstract
Pd on three dimensional (3D) porous carbon (Pd/PC) has been one-pot synthesized via in situ potassium hydroxide activation of PdCl62â-exchanged resin for the first time. The anion-exchange resin not only anchors PdCl62â ions to obtain uniformly dispersed Pd nanoparticles but also acts as a carbon source. The Pd/PC composites exhibit an ultrahigh surface areas (2734-3316Â m2Â gâ1) and large pore volumes (1.789-1.991Â cm3Â gâ1). The excess hydrogen uptake of Pd/PC-850 reaches 4.6Â wt% at 77Â K and 20Â bar. At room temperature, the hydrogen spillover process from Pd nanoparticles to the 3D activated porous carbon has been clearly observed. The 1.86Â wt% Pd-containing composite (Pd/PC-850) displays a high hydrogen spillover enhancement (154%) at 298Â K.
