Sol–gel auto combustion synthesis, characterization, and application of Tb₂FeMnO₆ nanostructures as an effective photocatalyst for the discoloration of organic dye contaminants in wastewater

Abstract

In this study, new double perovskite Tb2FeMnO6 nanoparticles were successfully synthesized by a sol–gel auto combustion method for the first time. The photocatalytic properties of the nanoparticles were also evaluated for the first time.

Sodium Alginate–CdS Nanostructures: Reinforcing Chemoselectivity in Nitro-Organic Reduction and Dye Degradation through Photoinduced Electron Transfer

“…Furthermore, exploiting photocatalytic reactions to degrade organic dye effluents is an alternative to several water remediation processes because it is economically feasible and can be carried out in mild conditions, resulting in carbon dioxide and water as the major side products. − Therefore, there is significant interest in developing photocatalysts that can utilize visible light to catalyze these reactions. As a result, a variety of oxides, sulfides, and chalcogenides, in the form of nanostructures and thin films, are extensively investigated as photocatalysts. − Nevertheless, the majority of reported photocatalyst nanostructures are synthesized by high-temperature approaches, namely, sol-combustion, hydro/solvothermal, coprecipitation, and pyrolysis. − Additionally, a preferred photocatalyst should be innocuous, reusable, and chemically inert. Thus, it is imperative to synthesize photocatalysts that can efficiently use visible light in mild reaction conditions .…”

Visible-Light-Driven AO7 Photocatalytic Degradation and Toxicity Removal at Bi-Doped SrTiO3

“…Perovskite-type compounds, such as halide perovskites, have been studied as promising photocatalysts for some applications such as CO 2 reduction under UV–visible radiation [ 9 ] and PET–RAFT polymerization under visible and near-infrared radiation [ 10 ], due to their superior properties. Other types, such as perovskite oxides, have shown to be more suitable than their halide counterparts for application as catalysts in the photocatalytic degradation of aqueous solutions of several compounds, including organic dyes, due to their higher water stability [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. These ceramic materials, with the general formula ABO 3 , are well known for their stable and flexible structure that allows the accommodation of several cationic combinations and consequent variety of properties.…”
