Improvement of semiconductor oxide nanomaterials play a vital role in the photocatalytic activity of the photodegradation process. In this article, we compare the characterization property of photocatalytic activity of Bentonite clay supported ZnWO4 with heterostructured compound of BiVO4 – ZnO, and DyVO4 − ZnO. The active nanomaterials exhibit high reusability without any loss of photocatalytic property up to four successive stages. Our results give a new impact on the performance of photocatalysts on environmental remediation.
