- •
A hybrid structure of TiO2
ZnO/LECA was applied for photocatalytic removal of ammonia.- •
Hybrid photocatalyst had a significant effect on photoluminescence and UV–vis absorption.
- •
Coupled Ti:Zn photocatalyst (molar ratio = 1:2) exhibited max. photocatalytic degradation.
- •
Optimal conditions: pH ≈ 11, catalyst loading = 25 g/L, and initial concentration = 400 mg/L.
- •
In optimal conditions 95.2% ammonia removal was achieved during 3 h of UV irradiation.
