Poly(N-methylaniline)/nickel modified carbon paste electrode as an efficient and cheep electrode for electrocatalytic oxidation of formaldehyde in alkaline medium

Electrocatalytic oxidation of formaldehyde on nickel modified ionic liquid carbon paste electrode as a simple and efficient electrode

“…Recently, we have demonstrated that incorporation of Ni(II) ions into the polymeric-modified CPE can successfully catalyze the oxidation of formaldehyde in alkaline media [28,29]. All these results encouraged us to continue the studies with new modified electrodes to improve the efficiency of electro-oxidation of formaldehyde at the surface of these electrodes.…”

Synthesis and characterization of nano-ZSM-5 zeolite and its application for electrocatalytic oxidation of formaldehyde over modified carbon paste electrode with ion exchanged synthesized zeolite in alkaline media

“…Formaldehyde, has prompted its use as a model to gain insight into the processes of the electro-oxidation of small molecules, a subject of long-term interest in the development of the fuel cell technology [3]. The mechanism of formaldehyde oxidation has been studied under a wide range of conditions and over various electrodes including binary and ternary alloys [4], pt and polymeric modified electrodes [5,6]. The use of zeolites as supported electrodes represents a good feature for preparation of modified electrodes for fast, easy and cheap for electrooxidation of fuels in fuel cells.…”

Physioelectrochemical Investigation of Electrocatalytic Activity of Modified Carbon Paste Electrode in Alcohol Oxidation as Anode in Fuel Cell

“…In the cases where γ>1.5, erf (γ 1/2 ) is almost equal to unity and the above equation can be reduced to 19) : (2) From the slope of the I C /I L versus t 1/2 plot, presented in Fig. 6c, the mean value of k for the concentration range of 0.1 to 0.…”

“…On the basis of this rate equation the faradic current will be: (19) Where A being the surface area of the electrode and the corresponding charge transfer resistance is: (20) This last equation is well suited for the calculation of the rate constants and the validity test of the kinetics and the mechanism. The methanol concentrations dependency of Rct is presented in 11 shows the current density of some electrodes for oxidation of methanol in same concentration with compared to NCMCPE.…”
