Abstract

SYNTHESIS OF CARBON-SUPPORTED PT/C CATALYSTS USING A NEW PREPARATION TECHNIQUE, A WATER-IN-OIL MICROEMULSION OR REVERSE MICELLE METHOD, IS REPORTED. THE INFLUENCE OF THE CETYL-TRIMETHYLAMMONIUM BROMIDE (CTAB) CONCENTRATION, AS A SURFACTANT, OVER THE REVERSE MICELLES SIZE AND THEN OVER THE PT NANOPARTICLE SIZE WAS STUDIED. THE CATALYSTS WERE CHARACTERIZED BY ELECTROCHEMICAL AND SURFACE TECHNIQUES SUCH AS: CYCLIC VOLTAMMETRY, CHRONOAMPEROMETRY, LINEAR SWEEP VOLTAMMETRY IMPEDANCE SPECTROSCOPY, X-RAY DIFFRACTION AND SCANNING ELECTRON MICROSCOPE. SURFACE AND ELECTROCHEMICAL CHARACTERIZATIONS SHOWED THAT PT NANOPARTICLES ON CATALYSTS WERE SYNTHESIZED SINCE THE REVERSE MICELLE METHOD WAS USED. THE PERFORMANCE OF THE PT/C CATALYSTS WAS TESTED BY THE ROTATING DISK ELECTRODE AND 3-ELECTRODE TECHNIQUES. A TREND OF CATALYTIC ACTIVITY FOR OXYGEN REDUCTION REACTION (ORR) WAS OBTAINED: PT/C(CTAB 0.11M) > PT/C(CTAB 0.22M) > PT/C(CTAB 0.055M) > PT/C(CTAB 0.5M) > PT/C(CTAB 0.022M), SHOWING THAT PT/C(CTAB 0.11M) CATALYST HAD A BEST CATALYTIC ACTIVITY FOR ORR.
