Triton X-100 effect on highly electrocatalysis of ethanaol oxidation based on nickel particles electrodeposited into poly (m-toluidine)

In this work, an aqueous solution of triton X-100 (TX-100) [t-octylphenoxypolyethoxyethnol] nonionic surfactant is used ia an additive for electropolymerization of m-toluidine (MT) onto carbon paste electrode (CPE) resulting (PMT(TX-100)/MCPE). The growth of polymeric film in the absence of TX-100 is poor, while it considerablyincreases in the presence of the surfactant. Then electrolysis at fixed potential (-1.0 V versus reference electrode for 15 min) is employed for electrodepositing of Ni from 1.5 M NiSO(4) acidic solution at the surface of polymer-modified electrode for preparation of (Ni/PMT (TX-100) MCPE). This polymeric modified electrode has a very good activity toward the ethanol electrooxidation in a 0.1 MNaOH solution. By comparison of the different responses to ethanol oxidation using electrodes Ni/PMT(TX-100)/MCPE and Ni/PMT.MCPE, we observed that NI/PMT(TX-100)MCPE is a more effective catalyst for the eclectrooxidation of ethanol.
