In ecological and environmental protection, photocatalytic degradation of toxic organic dyes is a challenging task. Oxide-semiconductor is a special category of materials with a nanostructure that has obtained more attention in recent times owing to their fascinating properties and an extensive choice of applications in photocatalysis. This chapter includes a critical review of oxide-semiconductor nanomaterials towards photocatalytic wastewater purification. The structural aspects, nanostructure formation process and the various parameters affecting catalytic activity, photocatalytic applications of ZnO, TiO2, Fe3O4, and CeO2 based catalysts for efficient photocatalytic degradation of organic dyes are reviewed. It also includes a brief discussion on the mechanism of photocatalysis. In this regard, various oxide-semiconductor and their composite nanostructures for degradation of various organic dyes are sketched.
