文摘
Monodisperse core-shell magnetic organosilica nanoflowers were prepared. CALB was immobilized on the nanoflowers via covalent bonding method. CALB@nanoflowers showed improved stabilities than CALB@MMPS. CALB@nanoflowers showed improved catalytic performance in the synthesis of alkyl levulinates.
