CTAB effect on highly electrocatalysis of formaldehyde oxidation based on nickel particles electrodeposited into poly (m-toluidine) film on carbon paste electrode in alkaline medium

This research is aimed to increase the activity of anodic catalysts for formaldehyde electrooxidation. The electrocatalytic oxidation of formaldehyde on nickel particles electrodeposited into poly (m-toluidine) film on carbon paste electrode in the absence and presence of cetyltrimethyl ammonium bromide (CTAB) has been investigated. And The general electrochemical behavior was characterized by cyclic voltammetry in alkaline media. In alkaline medium (i.e. NaOH 0.1 M) a good redox behavior of Ni ()/Ni () couple at the surface of Ni/poly (m-toluidine) modified carbon paste electrode (Ni/PMT/MCPE) in (Ni/CTAB-PMT/MCPE) system can be observed. The results show that Ni/CTAB-PMT/MCPE system exhibits a significant electrocatalytic activity towards oxidation of formaldehyde.
