Rational design of the Z-scheme hollow-structure Co9S8/g-C3N4 as an efficient visible-light photocatalyst for tetracycline degradation

An efficient Z-scheme cage-structured Co₉S₈/g-C₃N₄ photocatalyst with hollow structure which accelerates the separation of photogenerated charge carriers was constructed for the degradation of tetracycline antibiotics under visible-light.
