DFT study of methanol adsorption on PtCo(111)
(Elsevier Science, 2017-10-31)
Methanol adsorption on PtCo(111) surface at low coverage is studied using Density Functional Theory (DFT) calculations without and with van der Waals corrections. We investigated the PtCo FCT alloy surface with a uniform ...
DFT study of benzene and CO co-adsorption on PtCo(1 1 1)
(Elsevier Science, 2014-01-19)
Co-adsorption of benzene and CO on PtCo(1 1 1) surface at low coverage is studied using density functional theory calculations. We investigated the PtCo FCT alloy surface with a uniform distribution. The most favorable ...
Electrodeposition of PVA-protected PtCo electrocatalysts for the oxygen reduction reaction in H2SO4
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In this paper we report the electrosynthesis of PVA-protected PtCo films (PVA = poly(vinylalcohol)) and their activities towards the oxygen reduction reaction (ORR). PtCo electrodeposits were potentiostatically obtained ...
Benzene adsorption on PtCo(1 1 1): A DFT study
(Elsevier, 2013-10-01)
Adsorption benzene on PtCo(1 1 1) surface at low coverage is investigated using density functional theory calculations. We have investigated the PtCo FCT alloy surface with a uniform distribution and two benzene orientation ...
Ab Initio Investigation of the Role of CO Adsorption on the Physical Properties of 55-Atom PtCo Nanoalloys
(Amer Chemical Soc, 2017-12-14)
The knowledge of the physical and chemical properties of PtCo nanoparticles as a function of the Pt/Co composition and atomic distribution is crucial for several potential applications, which includes catalysis, anticorrosion, ...
Dendrimer-carbon nanotube layer-by-layer film as an efficient host matrix for electrogeneration of PtCo electrocatalysts
(Royal Society of Chemistry - RSCCambridge, 2014-02)
In this paper we demonstrate that layer-by-layer (LbL) films of polyamidoamine (PAMAM) dendrimers and single-walled carbon nanotubes (SWCNTs) are efficient for controlling the morphology of electrogenerated cobalt (Co) and ...
Electrocatalysis of oxygen reduction on carbon-supported Pt-Co nanoparticles with low Pt content
(ELSEVIER SCIENCE BV, 2009)
The oxygen reduction reaction (ORR) was investigated on carbon-supported Pt-Co nanoparticle electrocatalysts with low Pt content in alkaline electrolyte. High resolution transmission electron microscopy, In situ X-ray ...
Adhesion and bonding of Pt/Ni and Pt/Co overlayers: density functional calculations
(Pergamon-Elsevier Science Ltd, 2006-04)
The electronic and energetic properties of bimetallic surfaces Pt/Ni(111) and Pt/Co(111) are examined using the FP-LAPW (Full-Potential Linearized Augmented Plane Wave) method by means of spin-polarized and non-polarized ...
Carbon-supported Pt-Co catalysts prepared by a modifled polyol process as cathodes for PEM fuel cells
(Amer Chemical Soc, 2007-02-22)
In this work, carbon-supported Pt70Co30 nanoparticles were prepared by a polyol process using a long-chain diol as reducer (hexadecanediol) and oleic acid and oleylamine as stabilizers. Depending on the synthesis conditions, ...
