Abstract

HYDROGEN AS A GREEN ENERGY CARRIER HAS SOME ADVANTAGES SUCH AS HIGH ENERGY CAPACITY, ECO-FRIENDLY, HIGH SAFELY, HIGH CLEAN AND IDEAL ENERGY SOURCE [1]. THE COMBUSTION PRODUCTS OF HYDROGEN ARE FREE FROM POLLUTION [2]. GRAPHENE AS A TWO-DIMENSIONAL (2D) HONEYCOMB LATTICE OF CARBON ATOMS IS THE BASIC STRUCTURAL UNIT OF SOME CARBON ALLOTROPES INCLUDING GRAPHITE, CARBON NANOTUBES AND FULLERENES [3]. IN ONE VIEWPOINT, IT IS THE MOTHER OF ALL GRAPHITIC MATERIALS [4]. SYNTHESIS OF METAL NANOPARTICLES (NPS) WITH CONTROLLED SIZE, UNIFORM MORPHOLOGY, GOOD CRYSTALLINITY AND HIGH DISPERSION ARE GREAT IMPORTANCE. FOR THIS PURPOSE, REDUCED GRAPHENE OXIDE (RGO) AS A GOOD 2D SUPPORT TO NUCLEATE AND ANCHOR METAL NPS ON THE EDGES AND SURFACE IS EXPECTED TO BE AN IDEAL CATALYST CARRIER. IN THIS WORK, A ONESTEP FACILE ELECTROCHEMICAL METHOD WAS USED TO PREPARATION OF RGO AND PD NPS ON CARBON PASTE ELECTRODE. THE RESULTED NANO COMPOSITES (PD-RGO) WERE CHARACTERIZED WITH SCANNING ELECTRON MICROSCOPE (SEM), CYCLIC VOLTAMMETRY (CV) AND CHRONOCOULOMETRY (CC) TECHNIQUES. THIS CATALYST SHOWED HIGHEST ELECTRO CATALYTIC ACTIVITY AND STABILITY TOWARD HYDROGEN EVOLUTION REACTION (HER). KINETIC PARAMETERS SHOW THAT THE VOLMER STEP MUST CONTROL THE HER. THIS STUDY SUGGESTS A FACILE, EFFECTIVE AND CONTROLLABLE METHOD FOR THE PREPARATION OF GRAPHEME-METAL NPS WITH HIGH ELECTRO CATALYTIC ACTIVITY.
