Title : Novel synthesis of mesoporous alumina by hydrothermal technique & their role as catalyst support for valuable chemicals


In recent years, inorganic materials with different shapes and microstructures have received considerable attention owing to the obvious dependence of their properties on their shape and texture. The materials with hierarchically macro-mesoporous structures are of great interest as potential catalyst supports, catalysts and adsorbents, which is due to their large specific surface area and, more important, their texture mesopores and intrinsic interconnected macropore network being able to efficiently transport guest species to framework catalytic sites. In addition, inorganic materials with hollow spherical structure show several advantages such as high mobility, good surface permeability, large specific area and low density. So, synthesis of such mesoporous assemblies and inorganic hollow spheres with hierarchically macro-mesoporous structures which are good candidates as catalyst supports can be discussed during the presentation. The synthesis and utility of γ-Al2O3, as well as other transition aluminas, can be traced to a favourable combination of textural properties (i.e., surface area, pore volume, and pore size) and acid base characteristics. Conventional forms of γ-Al2O3 typically exhibit a BET surface area below 250 m2/g and a pore volume less than 0.50 cm3/g. various methods have been reported on the synthesis of AlOOH and γ-Al2O3 used as adsorbents, filters, catalysts, and catalyst supports. Meso-structured aluminium oxides have been prepared using different surfactants as structural directing reagent. The use of mesoprous alumina as support with loading of different transition metal catalyst will lead to form a new platform in fine chemical industries to get high yield of product.
