ChemInform Abstract: Interactions of Molybdenum Oxide with Various Oxide Supports: Calcination of Mechanical Mixtures.
Abstract
Intimate mechanical mixtures of various support materials and an amount of MoO3 corresponding to less than a monolayer are calcined at 720 K and the calcined mixtures have been investigated by laser Raman and FTIR spectroscopy.
ChemInform Abstract
Intimate mechanical mixtures of various support materials and an amount of MoO3 corresponding to less than a monolayer are calcined at 720 K and the calcined mixtures have been investigated by laser Raman and FTIR spectroscopy. On TiO2, SnO2, Al2O3, and MgO supports, surface molybdate species are formed on calcination via thermally induced spreading of the bulk MoO3 phase. Interactions between support and MoO3 are sufficiently in these cases where no bulk MoO3 is detected, whereas weaker interaction is observed in the case of SiO2.
