Metal (Co, Mn)-amine-functionalized mesoporous silica SBA-15: synthesis, characterization and catalytic properties in hydroxylation of benzene

Mesoporous silica SBA-15 was synthesized using H 3 PO 4 and functionalized with ethylendiaminopropyltrimethoxysilane (H 2 N–(CH 2 ) 2 –NH–(CH 2 ) 3 –) by grafting method. A variety of transition metals such as Co and Mn have been coordinated with amine-functionalized silica SBA-15. The materials hav...

Description
Summary:Mesoporous silica SBA-15 was synthesized using H 3 PO 4 and functionalized with ethylendiaminopropyltrimethoxysilane (H 2 N–(CH 2 ) 2 –NH–(CH 2 ) 3 –) by grafting method. A variety of transition metals such as Co and Mn have been coordinated with amine-functionalized silica SBA-15. The materials have been characterized by XRD, FT-IR, BET, TGA, 13 C-NMR, DR UV–Vis, atomic absorption spectroscopy (AAS) and back titration using NaOH (0.1 N). The catalytic performance of obtained catalyst was determined for hydroxylation of benzene using H 2 O 2 as oxidant in the presence of O 2 atmosphere. At optimized conditions, the Mn-amine-functionlized mesoporous silica SBA-15 exhibited high catalytic activity at room temperature in the absence of solvent.
