ChemInform Abstract: Architecture of MoO3‐TiO2 Catalysts.

Abstract

ChemInform Abstract A series of MoO3-anatase catalysts are prepared by grafting and impregnation methods and characterized by XRD, FTIR, SEM, XPS, and ISS in order to determine the nature of MoO3 when the monolayer coverage is exceeded. It is established that well dispersed MoO3 can be obtained as a monolayer with the grafting method. The impregnation method leads to worse dispersion of MoO3 on the anatase surface due to clustering of molybdena. At MoO3 loadings higher than the theoretical monolayer coverage (6.3 wt.% MoO3) epitaxially grown MoO3 crystals appear and their epitaxial growth produces a specific morphology of the MoO3 crystals.
