Synthesis and characterization of ordered mesoporous materials and their application as supports in lipase immobilization

Abstract

Ordered mesoporous materials are widely used both as catalyst or support. In the present work, the role of various structural and chemical parameters in the immobilization capacity of Candida antartica B (CaLB) enzyme on OMM (Ordered Mesoporous Materials) was studied. Two types of porous structures were prepared: cylinder (SBA-15, KIT-6) and cage (SBA-16, FDU-12) type. Additionally, each material was synthesized in pure silica and methyl functionalized forms. Finally, the resulting catalysts were evaluated for the tributyrin hydrolysis reaction, and the leaching of enzyme in aqueous media was tested.
