Structural and surface properties of thermally prepared Ti/RhxTi(1-x)Oy electrodes: I - influence of preparation parameters
(Elsevier B.V., 2002-02-01)
Electrodes of RhxTi(1-x) O-y nominal composition were prepared by thermal decomposition of the chloride or nitrate precursor salts dissolved in strongly acidic medium and applied by brush to both sides of a Tidegrees ...
Iridium−Rhodium Nanoparticles for Ammonia Oxidation: Electrochemical and Fuel Cell Studies
(2017-05-01)
This study reports the use of carbon-supported IrRh/C electrocatalysts with different iridium-to-rhodium atomic ratios (0 : 100, 50 : 50, 70 : 30, 90 : 10, and 100 : 0) for ammonia electro-oxidation (AmER) in alkaline ...
rGO-ZnO nanocomposites for high electrocatalytic effect on water oxidation obtained by microwave-hydrothermal method
(Elsevier B.V., 2017-11-30)
Reduced graphene oxide-zinc oxide (rGO-ZnO) nanocomposites were successfully synthesized using a facile microwave-hydrothermal method under mild conditions, and their electrocatalytic properties towards O-2 evolution were ...
Influence of molar fraction of Mg/Al, on the electrochemical behavior of hycrotalcite-epoxy-graphite composites
(Elsevier B.V., 2020-10-01)
The layered structure of hydrotalcite-like compounds is responsible for many chemical and physical properties attractive in designing electrodes for analytical applications. Mg/Al hydrotalcite-like materials were prepared ...
Study of binary self-assembled monolayers of a novel anchoring thiol (11-mercaptoundecyl-N′,N″,N‴-trimethylammonium) in the electron transfer with glucose oxidase enzyme
(2018-04-01)
In this study, we explore the fabrication and properties of a sensing electrochemical platform that is based on a novel 11-mercaptoundecyl-N′,N″,N‴-trimethylammonium hexacyanoferrate (MAH) and 6-(ferrocenyl)hexanethiol ...
A magnetically drivable nanovehicle for curcumin with antioxidant capacity and MRI relaxation properties
(Wiley-Blackwell, 2014-09-08)
Curcumin possesses wide-ranging anti-inflammatory and anti-cancer properties and its biological activity can be linked to its potent antioxidant capacity. Superparamagnetic maghemite (gamma-Fe2O3), called surface-active ...
Long-Lasting Oscillations in the Electro-Oxidation of Formic Acid on PtSn Intermetallic Surfaces
(Wiley-Blackwell, 2014-06-23)
Even when in contact with virtually infinite reservoirs, natural and manmade oscillators typically drift in phase space on a time-scale considerably slower than that of the intrinsic oscillator. A ubiquitous example is the ...
Surface spectators and their role in relationships between activity and selectivity of the oxygen reduction reaction in acid environments
(2015-08-12)
Abstract We use the rotating ring disk (RRDE) method to study activity-selectivity relationships for the oxygen reduction reaction (ORR) on Pt(111) modified by various surface coverages of adsorbed CN<inf>ad</inf> ...
The oxidation of hydroxylamine on Pt-, and Pd-modified Au electrodes in aqueous electrolytes: Electrochemical and in situ spectroscopic studies
(2012)
The electrooxidation of hydroxylamine, NH2OH, in 0.1 M phosphate buffer (PB, pH = 7) on Pt-, and Pd-modified Au electrodes prepared by galvanic displacement of underpotential deposited Cu, was investigated by electrochemical ...
Determination of Metribuzin with a Cobalt Phthalocyanine-Modified Carbon Paste Electrode
(2018-07-24)
Metribuzin is a widely used pesticide with a half-life of up to 2 months and high affinity to organic matter that should be carefully monitored. Here is reported the development of a modified carbon paste electrode using ...
