Abstract

Fuel cells are a key new green technology that have applications in both transport and portable power generation. Carbon support-ed platinum (Pt) is used as an anode and cathode electrocatalyst in low-temperature fuel cells fuelled with hydrogen or low molecu-lar weight alcohols. The cost of Pt and the limited world supply are significant barriers to the widespread use of these types of fuel cells. Comparatively palladium has a three times higher abundance in the Earth’s crust. Here a facile, low temperature and scalable synthetic route towards 3D nanostructured palladium (Pd) employing electrochemical templating from inverse lyotropic lipid phas-es is presented. The obtained single diamond morphology Pd nanostructures exhibited excellent catalytic activity and stability to-wards methanol, ethanol and glycerol oxidation compared to commercial Pd black and the nanostructure was verified by small-angle X-ray scattering (SAXS), scanning tunneling electron microscopy (STEM) as well as by cyclic voltammetry (CV).
