Research on the electro-oxidation of glutathione (GSH) may give insight into its real oxidation mechanism on biomembranes. In the present work, the unusual oxidation process of GSH on an Au electrode was probed by cyclic voltammetry (CV) technique. Voltammetric studies showed that –SH in GSH was the unique target of electro-oxidation by excluding the other potential oxidation sites (amido group...

Two forms of the methanol electro-oxidation intermediate with stoichiometry C:H:O, COH (hydroxymethylidyne) and HCO (formyl), on Pt (111) with and without coadsorbed water were studied using density functional theory calculations. The structure, adsorption energy and stability with respect to dissociation were calculated. Both HC@O and C–OH were stable on clean Pt (111) and with a single coadso...

In-situ homogeneous dispersion of noble metals in three-dimensional graphene sheets is a key tactic for producing macroscopic architecture, which is desirable for practical applications, such as electromagnetic interference shielding and catalyst. We report a one-step greener approach for developing porous architecture of 3D-graphene/noble metal (Pt and Ag) nanocomposite monoliths. The resultin...

Although one dimensional (1D) Pt nanostructures with well-defined sizes and shapes have fascinating physiochemical properties, their preparation remains a great challenge. Here we report an easy and novel synthesis of 1D Pt nanostructures with controllable morphologies, through the combination of designer self-assembling I3K and phage-displayed P7A peptides. The nanofibrils formed via I3K self-...

Some classes of electrocatalysts based on Pt supported early transition metal carbides (TMCs) have shown promise for methanol oxidation reaction (MOR). To bridge the material gap, we studied some promising and new MOR. We synthesized 1%wt Pt/TMCs (TMCs group IV (Ti Zr), V (V, Nb Ta) VI (W)) via wet impregnation method as low loading MOR in alkaline media. The materials were characterized by X-r...
