Micro-and mesoporous carbide derived carbons synthesized from molybdenum and tungsten carbide were used as supports for platinum and Pt-Ru alloy catalysts. The scanning electron microscopy, X-ray diffraction, Raman spectroscopy, high resolution transmission electron microscopy and low temperature N 2 adsorption experiments were carried out to characterize the structure of prepared materials. The kinetics of oxygen reduction was studied using cyclic voltammetry and rotating disc electrode in 0.5 M H 2 SO 4 solution. The synthesized materials exhibited high specific surface area. The platinum or Pt-Ru alloy deposited onto the surface of carbon in the form of nanoparticles or agglomerates of nanoparticles. All catalysts showed high activity towards oxygen reduction.
