Study on the capacity of dye degradation and bacteria inhibiting property of (6Co/4Zn)ZIF composite

Abstract

In this work, the zinc/cobalt-based zeolite imidazolate framework-67 was synthesized using solvothermal method. Their application in the RhB dye degradation and inhibition of bacteria growth were investigated. The obtained materials were characterized utilizing scanning electron microscope (SEM), X-ray diffraction (XRD), and nitrogen adsorption-desorption isotherms. Our study reported the use of (6Co/4Zn)ZIF composite for the simultaneous treatment of both Rhodamine B dye and bacteria. The result showed that the prepared composite could remove RhB dye up to 95% by both adsorption and photodegradation, and exhibited good antibacterial activity against both Gram-negative E. coli (67,7% inhibition rate) and Gram-positive S. aureus (57,6% inhibition rate) under visible-light condition. Our study indicated that 6Co/4Zn)ZIF composite could be a potential material for the waste-water treatment ain textile industry.
