So,-gel process

A more detailed study of anatase crystallinity, by separating crystallite size (L) and lattice strain (e) according to Hall s equation [118], was carried out on four TiOj samples commercial photocatalyst ST-01, a precursor for commercial All photocatalyst, and TiOj powders prepared through so-gel process with different aging periods, 10 min and 24 h [98]. The rate constant for MB decomposition is plotted against L and c in Figures 3.6a and 3.6b, respectively. Dependences of on L and 8 can be approximated to be common among the four samples there is a maximum at L -32 nm and at 8 - 0.5 x 10 . It has to be pointed out that...

Different spectroscopic, microscopic and diffraction methods like IR and Raman spectroscopy, TEM or XRD were applied to characterize educts, intermediates or products of the sol-gel process. For a detailed insight into the mechanism of the fluorolytic sol-gel process, however, the application of NMR spectroscopy is the method of choice. The NMR experiments, both in liquid and in solid state, allow direct observations of local structures and their changes even if the matrices suffer from a loss of lattice periodicity. For the fluorolytic so-gel process both liquid state NMR experiments were realized for the alkoxide solutions, sols and thin gels as well as solid state MAS NMR experiments for the alkoxide, dried alkoxide fluoride gels and high-surface fluorides including H,...
