Abstract

Zn₂Ti1_-xFe_xO₄ (0 ≤x ≤0.7) photocatalysts were synthesized by polymerized complex (PC) method and investigated for its physico-chemical as well as optical properties. Zn₂Ti1_-xFe_xO₄ can absorb not only UV light but also visible light region due to doping of Fe in the Ti site of Zn₂TiO₄ lattice because of the band transition from Fe 3d to the Fe 3d + Ti3d hybrid orbital. The photocatalytic activity of Fe doped Zn₂TiO₄ samples for hydrogen production under UV light irradiation decreased with an increase in Fe concentration in Zn₂TiO₄. Consequently, there exists an optimized concentration of iron for improved photocatalytic activity under visible light (λ≥ 420 nm).
