Macroporous Ceramics Coated with Mesoporous Layer for Enzyme Encapsulation

Abstract:

Article Preview

Mesoporous silica with 5~10 nm pore size was coated over recycled ceramic, prepared from lake sludge, with pore size 100-200μm. The mesoporous silica coated ceramic was characterized by XRD, N2 sorption, SEM and TEM. The results clearly showed the formation of mesoporous coating on the macroporous ceramics. These ceramics with the mesoporous coating are specially suitable for stabilization of enzymes. The mesopore stabilized enzymes are recyclable catalysts and showed comparable performance with the free enzyme.
