Elucidation of Mo-species in Mo-Silicalite-1 (MoS-1) molecular sieves through oxidative dehydrogenation of ethanol.

Abstract

Whenever a metal incorporated materials are synthesized, it invariably requires instrumental techniques, like FTIR, laser Raman Spectroscopy, TEM, ESCA, NMR, etc., combined with computer modeling to establish the nature of metallic species present in the sample. In this paper, a very well known reaction, namely, oxidative dehydrogenation of ethanol is carried out over Mo-silicate-1 samples. From literature, it is understood that the product distribution of the above reaction is very much specific, which depends on the nature of the active sites present in the catalyst. Hence, by analyzing the selectivity of the products in the above reaction over Mo-silicalite samples, an attempt to deduce the nature of Mo-species is presented.
