Electrocatalytic oxidation of methanol on ordered binary catalyst of manganese and nickel oxide nanoparticles

Considerable decrease in overvoltage of electro-catalytic oxidation of methanol by modification of carbon paste electrode with Cobalt(II)-clinoptilolite nanoparticles

“…These results illustrate that the Co(II)-NClin is a good electrocatalyst for the electro-oxidation of methanol (see reactions 5 and 6). Similar results have been reported for electrocatalytic oxidation of methanol by other modified electrodes [30,31]. The relative decrease of the cathodic peak current in presence of methanol is attributed to the partial consumption of cobalt oxy-hydroxide species for oxidation of methanol due to formation of cobalt hydroxide based on the following reactions:…”

Ag nanoparticles supported on nickel foam: a flexible 3D electrode for methanol electrocatalytic oxidation

“…It has been reported that b-NiOOH phase enhances the oxidation of organic molecules. 61 (c) The ion-implantation method effectively protects AgNPs from atmospheric oxidation.…”

Optimization of manganese oxide amount on Vulcan XC-72R carbon black as a promising support of Ni nanoparticles for methanol electro-oxidation reaction

“…The electrocatalytic activity of a binary electrocatalyst of NiO x and MnO x nanoparticles on glassy carbon electrode towards methanol oxidation was mainly dependent of the loading extent of NiO x nanoparticles. Its synergistic behaviour was predominant when small loading of NiO x was considered [27]. The high mass loading of MnO 2 in MnO 2 /3D-Ni nanocomposites improved its rate capability and cycling stability for highperformance supercapacitors.…”

“…Nickel-doped MnO x nanoparticles, dispersed onto different carbon powders (M1000, MM225 and E350), were employed as cathode electrocatalysts in direct borohydride fuel cells [33]. Only one article has studied methanol oxidation reaction on mixed NiO x and MnO x species that were prepared by their sequential electrochemical deposition on glassy carbon electrode [27]. Therefore, the preparation of NiÀMnO x /C electrocatalyst in the present work by this proposed method and its application in the field of direct methanol fuel cells could be considered as a novel study.…”
