AC Impedance tracking of glassy carbon activation
(Serbian Chemical Society, Belgrade, 2010)
Carbon materials, due to their physical and chemical properties, have found wide application in different electrochemical systems. They are often used as substrates for supercapacitors and different types of electrocatalysts. ...
Non-linear frequency response analysis of the kinetics of electrochemical reactions: a case study – ferrocyanide oxidation kinetics
(Serbian Chemical Society, Belgrade, 2010)
In general, electrochemical (EC) systems are non-linear, which means they respond nonlinearly to a frequency-dependent periodic input perturbation of high amplitude imposed around a steady-state. In addition, the kinetics ...
The study of the iron phosphate coatings porosity in bufered borate solution
(Serbian Chemical Society, Belgrade, 2010)
The iron phosphate layers on the low carbon steel surface slows steel corrosion in aggressive environments. The quality of the iron phosphate layer depends on the fraction of the total surface area covered by phosphate ...
Oxidation of formic acid on bulk and nanosized Pt-Co alloys
(Serbian Chemical Society, Belgrade, 2010)
Bulk Pt3Co and nanosized Pt3Co and PtCo alloys supported on XC-72 high area carbon were investigated as the electrocatalysts for the oxidation of formic acid. Cyclic voltammetry in 0.1 M HClO4 and stripping voltammetry of ...
Ethanol oxidation at Pt-based alloys and UPD modified Pt/C catalysts
(Serbian Chemical Society, Belgrade, 2010)
Activity of two alloys, Pt3Sn/C and Pt3Ru2/C, was compared with the activity of Pt/C modified with corresponding amounts of SnUPD (~25 %) and RuUPD (~40 %) in overall oxidation of ethanol. Pt3Sn/C, Pt3Ru2/C and Pt/C catalysts ...
Cyclic voltammetry study of electrochemically synthesized Ag/PVP nanocomposite
(Serbian Chemical Society, Belgrade, 2010)
Hydrogel nanocomposites of silver nanoparticles (AgNPs) and crosslinked poly(N-vinyl-2-pyrrolidone) (PVP) were synthesized in situ by a novel electrochemical method. PVPhydrogels, crosslinked by gamma-irradiation, were ...
