Highly efficient photocatalytic activity of visible-light-driven Mn2O3/WO3 nanocomposite

In this work, Mn2O3/WO3 photocatalysts were fabricated via a co-precipitation method for enhanced photocatalytic activity. PXRD, FTIR, UV–visible spectroscopy, PL, FE-SEM and BET analysis have been used to characterize crystallinity, metal bonding, absorption, defect states, surface morphology and p...

Description
Summary:In this work, Mn2O3/WO3 photocatalysts were fabricated via a co-precipitation method for enhanced photocatalytic activity. PXRD, FTIR, UV–visible spectroscopy, PL, FE-SEM and BET analysis have been used to characterize crystallinity, metal bonding, absorption, defect states, surface morphology and porosity properties of the materials. The as synthesized photocatalysts was evaluated by degradation of Methylene blue (MB) and Rose Bengal (RB) dyes under simulated visible-light irradiation. The Mn2O3/WO3 heterostructure's enhanced surface area, better light absorption, and efficient photogenerated carrier separation resulted in improved catalytic performance. Almost 80% photocatalytic degradation of MB and RB has been observed within 120 min.
