One-step synthesis of porous bimetallic PtCu nanocrystals with high electrocatalytic activity for methanol oxidation reaction.
The design of porous bimetallic nanocrystals (NCs) is very important for electrochemical energy conversion. Herein, we report an aqueous solution method for one-step fabrication of porous PtCu NCs assembled by spatially interconnected arms in high yield by a simple ultrasonic treatment of the reaction mixture at room temperature. The proposed method, without the need for multi-step synthesis, h...
متن کاملOne-pot synthesis of monodisperse 5 nm Pd-Ni nanoalloys for electrocatalytic ethanol oxidation.
Highly monodisperse 5 nm Pd-Ni alloy nanoparticles (NPs) were prepared by the reduction of Pd(acac)(2)/Ni(acac)(2) mixtures with tert-butylamine-borane complex (TBAB) in the presence of oleic acid (OA) and oleylamine (OAm). Employing TBAB as an effective reductant and OA/OAm combination as an effective stabilizing agent is crucial to the formation of monodisperse Pd-Ni NPs. Experimental results...
متن کاملElectrocatalytic oxidation of ethanol on the surface of the POAP/ phosphoric acid-doped ionic liquid-functionalized graphene oxide nanocomposite film
In situ electropolymerization as a facile synthetic procedure has been used to obtain highly active compositesof ionic liquid functionalized graphene oxide(FGO)and poly ortho aminophenol (POAP). Surface and electrochemical analysis have been used for characterisation of FGO-POAP composite film. Nickel was accumulated by complex formation between Ni (II) in solution and amines sites in the polym...

متن کاملElectrocatalytic oxidation of methanol on platinum modified polyaniline electrodes
Electrocatalytic oxidation of methanol on Pt modified polyaniline electrodes was investigated with the aim of developing highly active composite electrodes for direct methanol fuel cells. Cyclic voltammetry and chronoamperometry were used to evaluate the catalytic activity in sulfuric acid solutions containing methanol. Pt / polyaniline modified carbon electrodes showed higher catalytic activit...
