In the last decade, manganese oxide nanostructures have become systems of particular interest as catalysts for oxidation reactions,,,,
We present a study on the catalytic oxidation of the organic dye morin by hydrogen peroxide in the presence of manganese oxide nanoparticles in aqueous solution
We presented a kinetic study of the catalytic oxidation of morin by H2O2 in aqueous solution using c*-disordered birnessite nanoparticles immobilized on cationic spherical polyelectrolyte brushes as catalyst
We demonstrate the catalytic activity and kinetic analyses of generation six poly(amido-amine) hydroxyl-terminated, G6-OH(Ptn) dendrimer-encapsulated nanoparticles immobilized onto mesoporous cobalt oxide for the catalytic oxidation of methylene blue
We demonstrate the synthesis and catalytic activity of different mesoporous transition metal oxides, silica, copper oxide, chromium oxide, iron oxide cobalt oxide, cerium oxide and nickel oxide, on the oxidation of a pollutant dye, Rhodamine B
These metal oxides were synthesized by inverse micelle formation method and characterized by transmission electron microscopy, scanning electron microscopy, X-ray diffraction, adsorption-desorption isotherms and H2-temperature programmed reduction
The adsorption process and the surface reaction are described by the thermodynamic adsorption constants K of
