Hierarchically Bimodal Porous Metallosilicate Catalysts for Acetolysis of Epichlorohydrin

Abstract:

The aim of this work was to prepare macrospherical catalysts which are easy to handle, recover and reuse. The metallosilicate macrospheres were obtained by incorporation of Ce(IV), Cr(III) and Zr within the silica framework using tetraethyl orthosilicate as silicon source. The yeast cells and chitosan were used as templates to generate the hierarchical multimodal porosity of the inorganic materials. The synthesized materials were characterized by water sorption technique, FTIR spectroscopy, DRX and SEM/EDAX analyses. Catalytic activity of the obtained metallosilicate macrospheres was analyzed in the acetolysis reaction of epichlorohydrin.

Keywords:
metallosilicate macrospheres; yeast cells; chitosan; heterogeneous catalysis;bimodal porous materials
