摘 要：Tungsten bronze （TB） type potassium strontium niobate KSr2Nb5O15 was prepared by solid-state reaction method, and was characterized by X-ray diffraction （XRD）,scanning electron microscopy （SEM） and UV-vis diffuse spectrum. The photocatalyst shows high photocatalytic activity of photodegrading acid red G. The effects of photocatalyst dosage and initial concentration of acid red G on the photodegradation process were studied. The kinetics of photocatalytic degradation of acid red G by KSr2Nb5O15 catalyst follows the first order reaction.
