The creation of hierarchical metal-organic frameworks (MOFs), which have promising high surface area, tunable pore environment, and functionalities, has always been of great interests for researchers. However, the control of the morphology of as-prepared MOFs and the creation of pores beyond the range of mesopore are still very challenging. Here we demonstrate a facile method utilizing a robust biological template, flagella, as the template to guide the synthesis of MOFs. We successfully obtained a uniformly tubular-shape MOF material with core-shell structure. The size of the template and the hybrid tube can both be tuned easily by adjusting synthetic conditions. This provides a useful tool to manipulate the morphology of MOFs and may have potential applications in drug delivery, sensing, and catalysis.
