Novel Zr(IV) and Hf(IV) – Schiff base complexes as white light photocatalysts for the degradation of methylene blue

Abstract

Untreated dyes found in industrial effluent damage aquatic habitats and diminish biodiversity. Therefore, dye-containing hazardous substances must be treated before being disposed of. Nowadays, TiO2 , ZnO, metal niobates and titanates, as well as other semiconductors with a large band gap, serve as the foundation for extensively used UV photocatalytic materials with high performance.
