Title

STUDY OF PLATINUM ELECTRODEPOSITION WITH CYCLIC VOLTAMMETERY METHOD FOR USING AS ELECTROCATALYST IN METHANOL OXIDATION REACTION

Abstract

 DIRECT METHANOL FUEL CELL IS AN ATTRACTIVE POWER SOURCE FOR PORTABLE POWER APPLICATIONS AND IN ELECTRICAL VEHICLES [1]. THE USE OF METHANOL AS FUEL HAS SEVERAL ADVANTAGES IN COMPARISON TO HYDROGEN: IT IS A CHEAP LIQUID FUEL, EASILY HANDLED, TRANSPORTED, AND STORED, AND WITH A HIGH THEORETICAL ENERGY DENSITY [2–4]. ALTHOUGH A LOT OF PROGRESS HAS BEEN MADE IN THE DEVELOPMENT OF DMFC, ITS PERFORMANCE IS STILL LIMITED BY THE POOR KINETICS OF THE ANODE REACTION [4–6]. PLATINUMBASED NANOMATERIALS SUPPORTED ON CARBON (E.G., PT/C) ARE COMMONLY EMPLOYED ELECTROCATALYST IN DMFCS [7]. THE ELECTRODEPOSITION METHOD FOR PREPARING PLATINUM ELECTROCATALYST IS RAPID AND FACILE, ALLOWING EASY CONTROL OF THE NUCLEATION AND GROWTH OF METAL NANOPARTICLES [8-9].IN THIS WORK, CYCLIC VOLTAMMETRY (CV) METHOD (VOLTAGE RANGE: -0.25 TO 0.65 V VERSUS AG/AGCL AND 50 MVS-1 SCAN RATE) WAS USED FOR PLATINUM ELECTRODEPOSITION ON CARBON VULCAN XC-72 PASTE ON CARBON PAPER SHEET. THE EFFECT OF SCAN NUMBER OF CV METHOD ON PERFORMANCE OF PREPARED PLATINUM ELECTROCATALYST WAS STUDIED. FOR DOING THAT, THE SCAN NUMBERS WERE VARIED 10 UP TO 50.THE CYCLIC VOLTAMMETRY AND LINEAR SWEEP VOLTAMMETRY (LSV) METHODS WAS USED TO ESTIMATE THE BEHAVIOR OF THE FABRICATED ELECTRODES IN 1 M KOH AQUEOUS SOLUTION AT A SCAN RATE 100 MVS-1 IN PRESENCE OF 1 M METHANOL AT ROOM TEMPERATURE.AS IT WAS SHOWN IN FIGURE 1 & 2, THE SCAN NUMBER OF CV AFFECTS ON EFFICIENCY OF FABRICATED ELECTRODES. ACCORDING OUR RESULTS, THE 30 SCAN NUMBER IS OPTIMIZED CONDITION. ALSO, OPTIMIZED ELECTRODE HAS GOOD OPEN CIRCUIT VOLTAGE AND HIGH CURRENT DENSITY FOR METHANOL OXIDATION REACTION.
