AB  - Platinum was incorporated into the cavities of NaX zeolite by impregnation/thermal decomposition technique, using Pt(II)-
acetylacetonate in acetone as an impregnating solution. The platinum-to-zeolite weight ratio amounted to 0.092. The sample was characterized by
thermogravimetry, X-ray diffraction and 23Na MAS NMR methods. The mixture of modified zeolite and 10 wt. % of carbon black, in a form of thin
layer, was pasted to a glassy carbon surface. With such an electrode material, the electrochemical decomposition of aqueous 2.5 mM H2SO4 + 1 M
Na2SO4 solution with hydrogen and oxygen production has been kinetically studied. In comparison with smooth polycrystalline platinum, this
electrode material provided an remarkable overvoltage drop for water splitting, primarily due to the acceleration of oxygen evolution reaction.

AB  - Nanodispersed metallic clusters of platinum and palladium were incorporated into NaX 
zeolite cavities by impregnation with acetone solution of corresponding acetylacetonates, solvent 
evaporation and acetylacetonate thermal decomposition. The acetylacetonate decomposition was 
followed by thermogravimetry. Modified zeolite samples were characterized by x-ray 
diffractommetry. In order to get a satisfactory electronic conductivity of modified zeolite, 10 % wt 
of carbon black was added. This material was applied to a rotating glassy carbon disc electrode, and 
was used to study electrochemical water splitting in slightly acidic aqueous solutions. Noble metal 
modified zeolites exhibit significant reduction in water decomposition overvoltage as compared to 
smooth polycrystalline platinum.
