Abstract :

Zeolites have the chemical formula Mx/n[(AlO2)x(SiO2)y].wH2O, where the charge-balancing nonframework cation M has valence n, x is 2.0 or more, and y is the moles of water in the voids. The Al and Si tetrahedral atoms, or T-atoms, form a threedimensional (3D) framework of AlO4 and SiO4 tetrahedra linked together by shared oxygen ions. Although SiO4 tetrahedra are charge balanced, AlO4 tetrahedra has a negative charge balanced by a positive charge on M while water molecules lie within the pores of zeolites. The water can be expelled upon by heating and evacuation and may be replaced by a number of small inorganic and organic guests. We are developing novel nanoporous zeolite materials for the treatment of waste including radioactive, toxic gas/chemicals separation, pesticide/herbicide management, sewage treatment etc. Zeolite acts as auxiliary as well as functional support in gas sensing. Zeolites has been modified dually i.e. both surface modified and ion exchanged present inside in the pore cavity. Also several polymer based composites has been synthesized for gas sensing purposes. This modification in zeolite structure increases its sorption capacity, sensitivity and recyclability. The parent sodium form was also modified to proton form to increase their catalytic activity and further applying for organic drug synthesis. Recent publications 1.
