Abstract

newlineABSTRACT newline newlineThe thesis was embodied with the Synthesis, characterization, catalytic and newlinebiological activity studies of some metal incorporated and acid functionalized newlineMCM-41 mesoporous materials . Accordingly, the entire research work and the newlinerelated literature review were presented in seven consecutive chapters. newlineChapter 1: Introduction newline newlineThe introduction of the work was discussed in chapter 1. In this chapter, the newlinebackground of mesoporous materials, and in particular the properties and catalytic newlineapplications of MCM-41 was presented.Among the broad range of applications newlineexhibited by these materials, mainly their role as photocatalysts, adsorbents, newlineheterogeneous catalysts and antimicrobial agents were given more importance. These newlineaspects have driven to template the scope and objectives of the present research work. newlineChapter 2: Materials and Methods newline newlineThe materials used for the research work and the methods incorporated in the newlinesynthesis of the mesoporous materials, organic derivatives were given in chapter 2. newlinePure MCM-41, metal incorporated mesoporous materials like Mn and Al-MCM-41, newlineacid functionalized mesoporous materials like sulphonic acid (-SO3H) and newlinephosphotungstic acid (H3PW12O40) functionalized MCM-41 materials were newlinesynthesized using co-precipitation method. These materials were characterized using newlineXRD, FTIR, SEM-EDS, N2 adsorption-desorption, and UV-Vis DRS instrumental newlinetechniques. The photocatalytic activity studies were conducted using photocatalytic newlinechamber and the absorbance was studied using UV-Vis Spectrophotometer. Atomic newlineabsorption spectrophotometerwas used to record the concentration of the metal ion in newlineits aqueous solution, before and after contact with the mesoporous materials. newlineSimilarly, the chalcone derivatives (3a-e) synthesized with the catalytic role of newlinethesemesoporous materials were characterized using newline1 newline13 newlineHNMR, newlineCNMR and Mass newlinespectral techniques. newlineChapter 3: Photocatalytic activity studies of metal incorporated mesoporous newlinesilica materials towards degradation of some organic dyes newline newlineT
