Effect of Pt-MOx (M = Fe, Co) interaction on the preferential oxidation of CO over Pt/MOx/TiO2 catalysts prepared by selective electrostatic adsorption
(Elsevier B.V., 2019)
In this work, the catalytic properties of Pt/MOx/TiO2 (M = Fe, Co) catalysts prepared by strong electrostatic adsorption (SEA), were investigated for the preferential oxidation (PROX) of CO in H2. The SEA method was chosen ...
On the apparent lack of preferential site occupancy and electrooxidation of CO adsorbed at low coverage onto stepped platinum surfaces
(ELSEVIER SCIENCE INC, 2011)
We report time evolution studies of low coverage CO adsorption (surface hydrogen site blocking < 40%) and oxidative stripping on stepped Pt(776) and Pt(554) surfaces. It was observed that there is no preferential site ...
Counterion association to cationic polyelectrolytes in methanol/water mixtures
(1995)
The effect of the nature of the medium on the chloride and bromide condensation to a cationic polyelectrolyte was studied. Methanol/water mixtures were used as solvent in order to vary continuously the properties of the ...
PREFERENTIAL ADSORPTION DETERMINED BY SPECIFIC INTERACTIONS - POLY(DIALKYL ITACONATES) 1,4-DIOXANE/METHANOL
(AMER CHEMICAL SOC, 1990)
The variation of the preferential adsorption coefficient, lambda, with the solvent composition, for a series of poly(dialkyl itaconates) is studied in the mixed solvent 1,4-dioxane/methanol. In these systems specific ...
Synthesis, reactivity ratios, and solution behavior of vinylpyrrolidone-co-monoalkyl itaconate and vinylpyrrolidone-co-dialkyl itaconate copolymers
(AMER CHEMICAL SOC, 1997)
Copolymers containing vinylpyrrolidone and mono and dialkyl itaconate units with different length in the side chains were synthesized and characterized. Copolymers of vinylpyrrolidone with three different compositions of ...
Density functional study of acrolein adsorption on Pt (111)
(Pergamon-Elsevier Science Ltd, 2014-01)
The electronic structure and bonding of acrolein (propenal) adsorption on Pt (111) were studied by density functional calculations (DFT). We optimized different adsorption configurations on the surface using the VASP code. ...
Negligible effects of tryptophan on the aflatoxin adsorption of sodium bentonite
(Taylor & Francis, 2014-11)
The main objective of this study was to determine if the competitive adsorption of tryptophan (Trp) and aflatoxin B1 (AFB1) could potentially affect the ability of a sodium bentonite (NaB) to prevent aflatoxicosis in ...
DFT study of adsorption and diffusion of atomic hydrogen on metal surfaces
(Elsevier Science, 2017-10)
An extensive study of adsorption and diffusion of hydrogen atoms on (100) surfaces of fcc Au, Cu, Ag and Pt was performed by means of DFT calculations. Bulk properties of those metals were calculated and compared with ...
A DFT study of cyclopropane adsorption on Pt(1 1 1) : electronic structure and bonding
(Elsevier Science, 2014-03)
We have studied the adsorption of cyclopropane (c-C3H6) on Pt(1 1 1) by means of the density functional theory (DFT). We have investigated the preferential adsorption geometry, considering different adsorption sites and ...
