Preparation of Ag-AgVO/g-CN composite photo-catalyst and degradation characteristics of antibiotics.

The degradation of tetracycline by silver vanadate (AgVO), graphite-like carbon nitride (g-CN) and their composites was studied by visible light photocatalysis. Their structures and morphologies were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Their degradation intermediates were analyzed by GC-MS.
