Abstract

Pollutants from textile industries into water-bodies have caused huge environmental hazards. The semiconductor mediated photocatalytic purification of polluted water is a promising environmental remediation technology. In the present study MnWO₄-TiO₂ composite nanoflowers endowed with efficient photocatalytic activity have been successfully synthesized by facile hydrothermal approach. XRD, SEM, TEM, EDX spectroscopy and UV-DRS were used to characterize the as-synthesized samples. The average size of composite nanoflower is ∼2 μm while the nanorods constructing the nanoflowers had the average diameters of 90 nm. The photocatalytic activity of the MnWO₄-TiO₂ nanoflowers for the degradation of methyl orange (MO) in visible light was much higher than of pristine TiO₂ nanorods and MnWO₄ nanoflowers respectively. The superior photocatalytic activity could be attributed to the formation of a MnWO₄-TiO₂ heterojunction in the MnWO₄-TiO₂ nanoflowers.
