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.

CeO 2 -C(Vulcan) catalyst materials activated with Pt nanoclusters have been synthesized using different methods comprising microwave synthesis, reduction with hydrogen and reduction with NaBH 4 . The materials have been analyzed using low temperature nitrogen adsorption, X-ray diffraction and scanning electron microscopy with energy-dispersive X-ray spectroscopy methods. Methanol oxidation has been studied using cyclic voltammetry, chronoamperometry and impedance methods. Very noticeable influence of catalyst surface structure and porosity, depending on the complex catalyst preparation conditions, has been demonstrated. High electrochemically active surface area values have been calculated. High current densities of MeOH oxidation have been established for several catalysts. Fitting of the impedance data has been performed, and the results have been discussed.

Platinum-praseodymium oxide complex catalysts on carbon support material have been synthesized at different conditions. Various physical methods have been used to characterize the studied materials. The catalytic activity toward methanol electrooxidation was studied using electrochemical methods and results were compared to a platinum-cerium oxide containing catalyst as well as Pt-C catalysts. High activity toward methanol electrooxidation was observed for the synthesized platinum-praseodymium oxide complex catalysts.
