Estimating the true catalytically active surface area for complex 3-D surfaces such as powders is both important for evaluating the true catalytic performance of the material and difficult. Since most industrially relevant catalysts are metallic particles supported on Carbon or Oxides evaluating their chemically relevant surface area is even more difficult. In an effort to better quantify the active surface area of supported catalysts we synthesized an unsupported phase pure and compositionally homogeneous PdZn powder and evaluated by DFT and experiments the thermo- and electro-chemical adsorption of H2, O2, and CO on the powder. These benchmark values can be used to evaluate the available surface area of supported catalysts as well.
