- W2047483445 abstract "Salts of 12-molybdophosphoric acid supported on silica were prepared by exchange of the supported parent acid with cesium, lithium, barium, magnesium, bismuth, aluminum, iron, silver, cobalt, chromium, copper, cadmium, mercury, nickel, lead, or vanadyl cations. Each of the supported salts was compared with supported free 12-molybdophosphoric acid and with the silicasupported cation as catalysts in the oxidation of methane by N2O. Three effects on the properties of the supported 12-molybdophosphoric acid catalyst due to the addition of cations have been discerned. One is attributable to the removal of protons by substitution, leading to the blocking of the oxygen extraction step which generates vacancies in the Keggin structure. This blocking effect does not depend on the nature or charge of the cation. The second effect appears to have an electronic basis and is strongly dependent on the nature of the cation. The relationship of this electronic effect to the electronegativity is discussed. A third effect of the added cation is the generation of new sites related to the intrinsic activity of the cations themselves." @default.
