Visible light driven instantaneous photocatalytic degradation of aniline blue (AB) and methyl violet (MV) by strontium ferrite nanoparticles

Abstract

Toxic organic dyes released into aquatic sources as a result of industrial activities pose a significant threat to the environment. The removal of such dyes from water sources is a challenging task in the context of environmental emergencies. In this present effort, the strontium ferrite nanoparticles were synthesized by coprecipitation followed by a calcination method and is applied for photocatalytic degradation of such organic dyes.The ferrite nanoparticles were characterized by FTIR, XRD, VSM, SEM-EDX, TEM, and HR-TEM studies. In the existence of H 2 O 2 under visible light, the catalyst performs efficient degradation of aniline blue (AB) and methyl violet (MV) dyes in a remarkably short interval of time. The superparamagnetic performance of the catalyst was confirmed by VSM, and thus it can be easily recovered from the degraded dye by applying an external magnet. The Fenton mechanism justifies the elevated rate of photo degradation, which generates hydroxyl and perhydroxyl radicals in the progress of the reaction.

Green synthesis and characterization of Ni0.25Zn0.75Fe2O4magnetic nanoparticles and study of their photocatalytic activity in the degradation of aniline

“…[19][20][21] Numerous researchers have lately begun employing magnetically separable ferrites as photocatalysts for the photodegradation of hazardous contaminants. [22][23][24] The greatest difficulty in separating the photocatalyst from the reaction medium may be overcome by using a recoverable magnetic ferrite as a catalyst. Using an external magnet, the catalyst may be successfully extracted.…”
