Abstract

In this research work Z-scheme based photocatalyst BiVO₄/Ag/NiFe₂O₄ was prepared through the facile hydrothermal method. The morphology, structural and optical properties of the synthesized photocatalysts were investigated by SEM, XRD, PL emission and UV–Vis absorption spectroscopy. The experimental results showed that the ternary BiVO₄/Ag/NiFe₂O₄ composites have a monoclinic structure, average crystallite size 40 nm, rod shape nanostructures, lowest recombination rate and absorption region is in the range of 700 nm. The effectiveness of the photocatalyst was further analyzed by the effective and rapid removal of azo dye, phenol and hydrogen evolution. The BiVO₄/Ag/NiFe₂O₄ nanocomposite degraded 100% azo dye and phenol in only 30 min and 35 min respectively. The prepared composite BiVO₄/Ag/NiFe₂O₄ yield hydrogen energy 452 μmolh⁻¹ g⁻¹. This composite exhibited excellent stability over the third cycle and degraded azo dye 98% in 30 min. The excellent efficiency of BiVO₄/Ag/NiFe₂O₄ was due to the high crystallinity, small recombination rate and large absorption region. This study offers a potential route for the exploration of the photocatalytic performance of BiVO₄/Ag/NiFe₂O₄ nanoparticles under visible light irradiation.
