Catalysis by Ferrites and Cobaltites for the alkylation and oxidation of organic compounds

Abstract

Catalysis is a very important process from an industrial point of view since the production of most industrially important chemicals involves catalysis.Solid acid catalysts are appealing since the nature of acid sites is known and their chemical behavior in acid catalyzed reactions can be rationalized by means of existing theories and models. Mixed oxides crystallizing in spinel structure are of special interest because the spinel lattice imparts extra stability to the catalyst under various reaction conditions so that theses systems have sustained activities for longer periods. The thesis entitledquot Catalysis By Ferrites And Cobaltites For The Alkylation And Oxidation Of Organic Compounds quot presents the preparation ,characterization ,and activity studies of the prepared spinels were modified by incorporating other ions and by changing the stoichiometry.The prepared spinels exhibiting better catalytic activity towards the studied reactions with good product selectivity.Acid base properties and cation distribution of the spinels were found to control the catalytic activity.
