Abstract Electro-oxidation of methanol in sulfuric acid solution was studied using palladium well-dispersed on titanium nanotubes, in relation to methanol oxidation processes in the direct oxidation methanol fuel cell. Pd dispersed on titania nanotubes, which leads to high surface area substrates, showed excellent catalytic activities compared to those of pure Pd and Pd–TiO2 nanoparticles. T…
Abstract. We demonstrate the use of molecular monolayers to enhance the nucleation of electrocatalytically active platinum (Pt) nanoparticles onto multi-walled carbon nanotubes (MWCNTs). The MWCNT is embedded within the 1,4-benzenediamine shell (NH2–MWCNT) with large amounts of amino groups outside on the nanotube surfaces. Subsequent deposition of platinum nanoparticles led to high densi…
