英文摘要 | A step-by-step self-assembly and concurrent self-etching strategy that differs from previous methods used to prepare sio2@uio-66-nh2 hollow composite has been reported. the magnetic core was selectively etched to generate a hollow metal-organic framework superstructure. the physical and chemical properties were characterized by tem and sem techniques, composition by sem-edx. benefit from the efficient mass transfer and enhanced active sites accessibility, the hollow sio2@uio-66-nh2 composite showed higher or comparable catalytic activity than the nano-sized uio-66-nh2 in the knoevenagel condensation as a solid basic catalyst. furthermore, it could be recovered and stable in terms of activity and structure when recycled for at least four times.
