摘要：
In this study, hierarchically macro/mesoporous silica sphere (HMMS) with structural macropores and skeleton mesopores was fabricated and adopted as an ideal carrier for immobilization of catalase (CAT). Compared with a commercial mesoporous silica (CMS) carrier, HMMS can immobilize much more CAT (270-300 mg/g carrier) than the CMS (90-120 mg/g carrier). Moreover, the immobilized CAT on HMMS exhibits comparable catalytic efficiency to the Carrier-free CAT, and possesses appreciable reusability. These superiorities make HMMS a promising carrier for enzyme immobilization. (C) 2017 Elsevier B.V. All rights reserved.
