Abstract:
1. A process for the preparation of ordered mesoporous titanosilicate (Ti—SBA-16) wherein the composition of mesoporous titanosilicate has a three dimensional cubic interconnected pore structure and is represented by the formula wherein x ranges from 0.001-0.05, with Ti is in a tetrahedral geometry and exclusively substituted for Si in the silica framework, wherein said process comprising the steps of: a. reacting F127 tri-block co-polymer (EO b. stirring the reaction mixture as obtained in step (a) for 20-24 hours to form a gel; c. crystallising the gel as obtained in step (b) at 353-373 K for 40-50 h to obtain titanosilicate (Ti—SBA-16); d. washing titanosilicate as obtained in step (c) with water and drying at 373-423 K followed by calcining in air at 823 K for 6-12 h to obtain titanosilicate (Ti—SBA-16).
