Abstract

Nowadays

efficient removal of antibiotic (

e.g.

tetracycline

TC) from water bodies has been of great global concern. Hereby

a novel Zn

SnO

/SnO

@ZIF-8 photo-catalyst was first synthesized by a facile self-assembly

in-situ

growth method. Zn

SnO

/SnO

@ZIF-8 exhibits a remarkable photocatalytic activity towards TC under visible-light driven with a rapid rate constant of 1.5×10

-2

min

-1

and a removal efficiency of 81.2%

which is superior to some catalysts in the literature. Importantly

the photocatalytic activity of Zn

SnO

/SnO

@ZIF-8 could still remain ~77% after the fifth cycle

indicating its good stability and reusability. The remarkable performances of adsorption and photocatalytic were attributed to associative effects of catalytic activity of Zn

SnO

/SnO

and the unique porous nanostructure and stability of ZIF-8. This work could aid the future design and preparation of novel MOFs composite catalysts for efficient elimination of antibiotics from water.
