ZIF-67-modified hollow vanadium dioxide core-shell structure micro-nano composite as well as preparation method and application of ZIF-67-modified hollow vanadium dioxide core-shell structure micro-nano composite

The invention discloses a metal-organic ligand framework ZIF-67 modified hollow vanadium dioxide core-shell structure micro-nano composite as well as a preparation method and application of the metal-organic ligand framework ZIF-67 modified hollow vanadium dioxide core-shell structure micro-nano composite. The metal-organic ligand framework ZIF-67 modified hollow vanadium dioxide core-shell structure multifunctional micro-nano composite has the advantages of being good in biocompatibility, low in toxicity, free of any adverse reaction on organs, antibacterial and capable of promoting angiogenesis. Compared with single nano VO2, the micro-nano composite provided by the invention has more excellent antibacterial property, catalytic activity and lower cytotoxicity, also has the function of promoting angiogenesis and accelerating healing of infected wounds, and can be applied to repair and regeneration of infected tissues. 本发明公开了一种金属-有机配体框架ZIF-67修饰的中空二氧化钒壳核结构微纳米复合物及其制备方法和应用。本发明的金属-有机配体框架ZIF-67修饰的中空二氧化钒壳核结构多功能微纳米复
