Novel Co-MOF/Graphene Oxide Electrocatalyst for Methanol Oxidation

Hydrothermal Syntheses of NiO−GO Nanocomposite on 3D Nickel Foam as a Support for Pt Nanoparticles and its Superior Electrocatalytic Activity towards Methanol Oxidation

“…The value of diffusion coefficient for methanol is calculated . This value indicates that MOR process on the Pt/NiO−GO/NF is controlled by the diffusion mechanism .…”

“…Therefore fabrication of catalytic anodes with anti‐poisoning property and high durability has attracted interests during recent decades. The most common catalytic anodes for MOR are Pt‐based catalysts . However, much effort for lessening of Pt consumption has been devoted because of high cost, scarcity and instability of Pt‐based catalysts.…”

A novel sensing layer based on metal–organic framework UiO-66 modified with TiO2–graphene oxide: application to rapid, sensitive and simultaneous determination of paraoxon and chlorpyrifos

“…30 After UiO-66 modification by TG, all diffractions belong to UiO-66 were well preserved, indicating that the presence of TG did not disturb the formation of crystals of UiO-66. [35][36][37] Notably, the broadened diffraction peaks indicated that T on the surface of GO (in the TG@UiO-66 matrix) has a low degree of crystallinity. 38 Furthermore, the absence of GO diffraction is due to the insertion of UiO-66 between TG layers that effectively reduces the van der Waals binding energy between the GO sheets and improves the layer exfoliation and also high dispersion of TG layers during the nanocomposite preparation can be another reason for this observation.…”

Development of an Efficient Non‐Noble Metal Based Anode Electrocatalyst to Promote Methanol Oxidation Activity in DMFC

“…This strategy can effectively mitigate this issue, e.g dopping different amount of Ru into Pt promote water oxidation near methanol oxidation potential, liberate OH ads species tuning CO to CO 2 with minimized Pt poisining. [8][9][10][11][12] Another reason for platinum inactivation is Ptelectrode deactivation under harsh conditions (acidic media) due to deposition of metals present as impurity in an electolyte during the analysis. Above mentioned problem can be resolved by in-situ reactivation process, where the polarity of electrolyte would be switched off (orginal polarity retained) and deposited impurities(metals) would be flushed out by the anodic oxidation in case of reduction process and vice versa for a sufficient time period under optimized conditions (temperature, current density etc) to prevent degradation and dissolution of electrocatalyst.…”
