Abstract
Abstract We report here the results from recent studies where in situ X-ray techniques have been employed to follow the structural evolution of complex oxide materials from amorphous precursors. Specifically we detail how combined X-ray absorption spectroscopy/X-ray diffraction (XAS/XRD) allowed us to obtain new insight into the heat-induced crystallization of industrially important bismuth molybdate catalysts (Bi2O3·nMoO3 where n = 3, 2 or 1 corresponding to the α, β and γ-phases) and nano-sized spinel (CoAl2O4) particles from amorphous zeolites. In addition we illustrate the power of the energy dispersive diffraction technique (EDXRD) to follow the evolution of bismuth molybdate phases in a real autoclave via low temperature (
