This study reports a novel approach to fabricate bacterial cellulose (BC) based multi-compartmentalized beads, which have significant potential for macroreactor for organic reaction. For this, we prepared cellulose-catalytic/magnetic nanoparticle composites such as palladium, gold and iron oxide through in situ reduction and impregnation method. The cellulose beads were made using the dissolution medium containing NaOH/urea mixture and acidic coagulation medium. We designed the tunable macroreactor to be driven under centrifugal force with a combination of micronozzles, which enables formation of compartment and mass production of cellulose beads within a few minutes. Through model organic reactions, we show that the BC bead catalysts play an essential role in enhancing the reaction kinetics and product yields. Moreover, iron oxide BC incorporated bead catalysts showed magnetic responsiveness, thus leading to effective recycling catalysts. |
