Today the development of economically viable hydrogengeneration technology that will allow realization of these important future applications is amatter of urgency.ExperimentalThe monometallic palladium and copper catalysts supported on multi-walled carbonnanotubes were prepared by conventional impregnation methods. The multi-walled carbonnanotubes were prepared by CVD method based on catalytic decomposition of 5% ferrocenein toluene at two temperatures 850 and 925°C. The obtained support material wasimpregnated by appropriate aqueous solution of palladium chloride and copper (II) nitrate(V). Then the catalysts were dried and calcined 4h in air at 400°C. The physicochemicalproperties of catalysts were examined by BET, XRD, XPS and TPR methods. Chemisorptionuptakes were measured using ASAP 2020C apparatus from Micromeritics (USA). Theactivity tests in methanol steam reforming (SRM) and methanol decomposition were carriedout over palladium and copper catalysts in the temperature range 160 to 320°C in a flowquartz reactor under atmospheric pressure, molar ratio H 2 O/CH 3 OH = 1 and 2.224
