Project Description

Heterogeneous catalysis plays an important role in Industry whether it is used for the production of fine chemicals or in the removal of hazardous contaminants. Various heterogeneous catalytic supports such as clays, microporous, mesoporous and macroporous materials have been used by industries for oxidation catalysis. Oxidation of pharmaceutically important oxidation catalysis involved diffusion of such bulkier reagents through the porous supports and forming a suitable transitional complex for shape selective products. However diffusional restriction of bulkier molecules through the micro / mesopores and the poor surface area of macroporous materials have led to the development of high surface area materials containing pore sizes on three different length scales i.e. micropores ( 50nm) with hierarchical ordering. Sen et al have reported [1,2,3] the fabrication of large surface area hierarchically ordered porous silicate materials with pore-interconnectivity in three length scales in a controlled fashion. Recently the same group has reported the simultaneous incorporation of magnetic and catalytic centres for the application in heterogeneous catalysis [5-8] and decomposition [9] of organic pollutants.

The proposed project is to expand our activity in the area of heterogeneous catalysis using such novel nanocomposites especially for the selective oxidation of bulkier organic molecules for industrial importance and photo-catalytic decomposition of toxic organic compounds for removal of organic pollutants from water as a part of our on-going project under UKIERI project [Contract no: IND/Cont (E) 14-15/ 055] funded by British Council, UK and Department of Science and Technology, India (2014-2016)
