Electro-Oxidation of Polyols on Bi-Modified Pt in Acidic Media (HClO4). Understanding Activity and Selectivity Trends Abstract: Herein we show that Pt(111) and Pt(100) can produce the ketone through the oxidation of the secondary carbon of […]
Impedimetric study of the electrocatalytic oxidation of alcohols by nickel-Schiff base metallopolymer: Potential application for forensic identification of alcoholic beverage contaminants by multivariate data analysis Abstract: The present paper presents a systematic electrochemical impedance study […]
Interfacial Characterization of Polypyrrole/AuNP Composites towards Electrocatalysis of Ascorbic Acid Oxidation Abstract: Polypyrrole (PPy) is an interesting conducting polymer due to its good environmental stability, high conductivity, and biocompatibility. The association between PPy and metallic […]
Short communication: Molecular architecture based on palladium-salen complex/graphene for low potential water oxidation Abstract: We have developed electrocatalytic platforms based on palladium metallopolymer-graphene for the water splitting reaction. The platforms presented a low potential for […]
Oscillatory Electro-oxidation of Methanol on Nanoarchitectured Pt-pc/Rh/Pt Metallic Multilayer Abstract: The oscillatory electro-oxidation of methanol was studied on polycrystalline Pt-pc and Pt-pc/Rh-2.0/Pt-1.0 metallic multilayers. The surfaces investigated consisted of 1.0 Pt outlayer surface deposited onto 2.0 […]
Metallic multilayered films electrodeposited over titanium as catalysts for methanol electro-oxidation Abstract: Multilayered Pt/Ir/Pt films were electrodeposited over titanium substrates, controlling the film thickness by the deposition charge. Two probe molecules were used to perform […]
Microwave-Assisted Synthesis of Pt-Au Nanoparticles with Enhanced Electrocatalytic Activity for the Oxidation of Formic Acid Abstract: We report the microwave-assisted hydrothermal synthesis of bimetallic Pt-Au nanoparticles with different Pt/Au mole ratio, and investigate their performance […]
