abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
palladium nanoparticles supported on multi-walled carbon nanotubes (pd/mwcnts) have been synthesized using a modified polyol reduction method and its performance in methanol oxidation reactions has evaluated. the morphology of palladium on mwcnts was characterized by scanning electron microscopy (sem) and transmission electron microscopy (tem). the catalytic performance of synthesized catalyst ...
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

The morphology of palladium on MWCNTs was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The catalytic performance of synthesized catalyst ...
a general overview on the prospective of various oxidation and combined processes in the treatment of tannery industry effluent are reported. various oxidation and combined processes such as uv/h2o2/hypochlorites, fenton and electro-oxidation, photo-chemical, photo-catalytic, electro-catalytic oxidation, wet air oxidation, ozonation, biological followed by ozone/uv/ h2o2, coagulation or ele...
background diatomite coated by nanoparticles of copper and zinc mixed oxides were used to investigate catalytic oxidation of carbon monoxide. objectives aim of this paper was to investigatediatomite performance as a supporting host to confine the cuo and zno nanoparticles and its catalytic activity for carbon monoxide oxidation. materials and methods the prepared catalysts were characterized by...
In this work, CuO nanoparticles (CuO NPs) was prepared by a simple and green method using Rosmarinus officinalis extract containing phenolic constituents as both the chelating and the stabilizing agents. CuO nanoparticles/polyorthoaminophenol composite (CuO NPs/POAP) as electro-active electrodes for electrocatalytic oxidation of methanol with good uniformity are prepared by electropolymerizatio...
In the present research, 4, 4'-biphenol was used as a homogeneous mediator for determining cysteine (CySH) on a Glassy Carbon Electrode (GCE). To describe the electrochemical properties of 4,4'-biphenol and to examine its electrocatalytic impacts on cysteine oxidation, both Cyclic Voltammetry (CV) and Linear Sweep Voltammetry (LSV) were employed. Our findings revealed that 4,4'-biphenol could s...
In the present work, the modified nickel electrode was electrochemically fabricated and tested for the electro-oxidation of paracetamol in alkaline media. The methods of cyclic voltammetry (CV), chronoamperometry (CA), and impedance spectroscopy (EIS) were used to determine kinetic parameters such as transfer coefficient (α), the catalytic reaction rate constants (k), and the diffusion coeffici...
