Removal of Erioglaucine Dye from Aqueous Medium Using Ecofriendly Synthesized ZnMnO₃Photocatalyst

Abstract

The hexagonal nanocrystalline ZnMnO3 powder was prepared from activated mixture by an ecofriendly solid state reaction using mechanochemical method. The synthesized catalyst was characterized by various investigative analytical techniques like Fourier Transform Infrared Spectroscopy (FT-IR), Ultraviolet-diffused reflectance Spectroscopy (UV-DRS), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) with EDAX, Transmission Electron Microscopy (TEM) and Brunauer-Emmett-Teller (BET) surface area. The average particle size of ZnMnO3 was found to be 82 nm. The photocatalytic activity of the prepared ZnMnO3 nanoparticles have been investigated by the degradation of Erioglaucine dye. It is revealed that the product exhibits a pronounced photocatalytic activity under the influence of UV-visible light irradiation. The degradation mechanism of Erioglaucine in presence of ZnMnO3 was established by using LC-MS technique.

Hybrid Composite of Sn(IV)-Porphyrin and Mesoporous Structure for Enhanced Visible Light Photocatalytic Degradation of Organic Dyes

“…The reaction mixture was analyzed by electrospray ionization–mass spectrometry (ESI-MS) after 45 min for each photodegradation experiment ( Figure S21 ). New peaks in the mass spectra confirmed the degradation of the EG dye to new small molecules [ 46 ]. Based on the mass spectra in Figure S16 , possible intermediates for the degradation of the EG dye are shown in Figure 10 .…”
