Magnetic mesoporous materials have attracted great interest due to their combined property of magnetic nanomaterials and mesoporous materials as well as their potential applications in catalysis, bioenrichment, drug delivery, nanoreactors, etc. In this study, one-dimensional (1D) podlike magnetic mesoporous silica nanochains with tunable hollow space (Fe3O4@nSiO2@void@mSiO2 nanochain named as podlike 1D magnetic mesoporous silica (PL-MMS) nanochain) are rationally synthesized for the first time through a controlled magnetic-induced interface coassembly approach. The obtained PL-MMS possesses a tunable diameter (300-500 nm), large and perpendicular mesopores (8.2 nm) in the outer shell, a silica-protected magnetic-responsive core, and a high surface area (325 m2/g). Benefiting from the large voids and unique mesopores, these mesoporous nanochains exhibit superior performance in enzyme (lipase with a size of 4.0 nm) immobilization with a high loading capacity of 223 ?g/mg, and the immobilized lipase demonstrates enhanced catalytic activity in different pH values and temperatures as well as excellent tolerance of organic solvent.
