Preparation of Pt/poly (2-Methoxyaniline)-sodium dodecyl sulfate composite and its application for electrocatalytic oxidation of methanol and formaldehyde

Electrosynthesized Ni-Al Layered Double Hydroxide-Pt Nanoparticles as an Inorganic Nanocomposite and Potentate Anodic Material for Methanol Electrooxidation in Alkaline Media

“…Figure 8 shows the effect of methanol concentrations on the electrooxidation current density of this fuel at the PtNPs/Ni-Al LDH/GCE in 0.5 M NaOH solution. It can be clearly observed that increasing the methanol concentration up to 0.6 M increases the anodic current density and, there is not any significant increase in the current density of methanol oxidation in methanol concentrations higher than 0.6 M. This effect might be due to the saturation of active sites on the surface of the electrode by methanol molecules and also contamination of the electrocatalyst surface which is mainly arisen from the COads intermediate during the methanol oxidation [64][65][66]. When the fuel concentration increases, the peak potential of the anodic peak in the forward and backward scan (inset of Figure 8 for forward scan) were shifted to high positive values.…”

Experimental Investigation of Methanol Conversion Factor to Formaldehyde in a Pilot Reactor

“…If the amount of methanol entering is not set, its extra amount in system decomposes into water and dimethyl oxide at generated high temperatures in reactor. Equation 4 shows this mechanism [20,21].…”

Synthesis of poly (2-Methoxyaniline)/sodium dodecyl sulfate film including bimetallic Pt–Cu nanoparticles and its application for formic acid oxidation

“…1A and B). The SDS may be affect the preparation of P2MA in three ways: (i) the presence of SDS micelles controls the electrode-electrolyte interface, thus altering the locus and course of electropolymerization, (ii) DS À may act as a counter ion for the CP polycations, and (iii) the hydrophobic part of the surfactant molecules may adsorb on the produced conducting polymer, SDS thus becoming a part of the resulting material [53,57].

“…All these reports reveal that these additives prepare new electrode materials with desired properties different from the normal polymers. Recently, we have prepared P2MA film in monomer solution containing SDS onto a glassy carbon electrode and used as a support for electrochemical deposition of Pt nano/microparticles for methanol and formaldehyde oxidation [53]. Surprisingly, the literature survey indicates that there is no report as yet on the application of P2MA-SDS modified popular CPE for deposition of bimetallic PteCu NPs and its application for electrocatalytic oxidation of formic acid in H 2 SO 4 solution.…”
