UV-visible spectroscopic study of solid state 12-molybdophosphoric acid catalyst Academic Article

abstract

• UV-visible spectroscopic studies of solid H3PMo 12O40were carried out to elucidate the effect of crystalline water molecules, and in turn, to provide a guideline for utilizing UV-visible spectra of solids to probe reduction potentials of HPA catalysts. UV-visible spectra of reduced/reoxidized H3PMo12O 40were also measured to check the possibility of utilizing UV-visible spectroscopy as a probe of reduction/oxidation states of H3PMo 12O40catalyst. Absorption edges of solid H 3PMo12O40 shifted to longer wavelength with heating to decrease the number of crystalline water molecules. It was also revealed that UV-visible spectra of the H3PMo12O 40catalyst varied in a systematic way depending on the reduction/oxidation states of the H3PMo12O 40catalyst. Akadmiai Kiad, Budapest.
