Abstract

IN THIS WORK, FOR THE FIRST TIME AN AQUEOUS SOLUTION OF TRITON X-100 (TX-100) NONIONIC SURFACTANT IS USED AS AN ADDITIVE FOR ELECTROPOLYMERIZATION OF O-TOLUIDINE (OT) ONTO MULTI-WALLED CARBON NANOTUBE PASTE ELECTRODE (CNTPE), WHICH IS INVESTIGATED AS A NOVEL MATRIX FOR DISPERSION OF CATALYSTS. THE AS-PREPARED SUBSTRATE IS USED AS POROUS MATRIX FOR DISPERSION OF TRANSITION METAL IONS OF NI(II) TO POT/TX-100 FILM BY IMMERSING THE MODIFIED ELECTRODE IN A 0.1 M NICKEL SULFATE SOLUTION. THE ELECTROCHEMICAL CHARACTERIZATION OF THIS MODIFIED ELECTRODE EXHIBITS REDOX BEHAVIOR OF NI(III)/NI(II) COUPLE. IT HAS BEEN SHOWN THAT POT/TX- 100 AT THE SURFACE OF CNTPE IMPROVES CATALYTIC EFFICIENCY OF THE DISPERSED NICKEL IONS TOWARD METHANOL OXIDATION. THEN, USING A CHRONOAMPEROMETRIC METHOD, THE CATALYTIC RATE CONSTANT, K, FOR METHANOL OXIDATION IS FOUND TO BE 7.40 ×104 CM3 MOL-1 S-1. AT THE END OF THIS WORK, LONG-TERM STABILITY OF THE MODIFIED ELECTRODE HAS BEEN INVESTIGATED.
