Preparation and Characterization of Amorphous Silica Organofunctionalised with 2-Mercaptobenzimidazole
Organofunctionalised silica materials are of great interest once they combine a high surface area and a narrow pore size distribution with the advantage of owing organic ligand properties. This paper describes the organofunctionalisation of an amorphous silica with 2-mercaptobenzimidazole. The characterization of such material was performed by elemental analysis (EA), IR spectroscopy, thermogravimetry (TG), differential scanning calorimetry (DSC) and solid state 13C and 29Si NMR spectroscopy.
