A comparative study of green and chemical approaches for photocatalytic activity of novel hybrid bismuth magnesium ferrites (BiMgFe2O4) nanoparticles for Acid Red-88 dye degradation

Abstract

Uncontrolled release of several dangerous pollutants had negatively impacted the environment causing water pollution and retarded plant growth. Recently, nanoferrites utilized as photocatalyst to eliminate water pollutants. The benefits of hybrid photocatalyst have significantly improved separating and charge transfer capabilities. In the present investigation novel bismuth magnesium ferrites (BMF - BiMgFe2O4) are synthesized via conventional solution combustion method using green and chemical approach. The particles are confirmed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM),Energy disperse X-ray diffraction analysis (EDX), UV-DRS (UV diffuse reflectance spectroscopy). The observed crystalline size for the nanoparticles synthesized by green and chemical approach is 25.15 nm and 18.55 nm respectively. Analyzed band gap observed is 2.89 eV and 1.98 eV for green and chemical approach that are confirmed by employing UV-DRS technique. The outcomes obtained from studies are verified with capable applications in photocatalytic degradation. The application of BiMgFe2O4 as catalyst for decolourisation of acid red 88 (AR-88) dyes under visible irradiation at room temperature exhibits superior photocatalytic activity for BiMgFe2O4 is 74.22% and 85.27% using green and chemical approach for 120 minutes respectively. It's significant that the environmental impact of the whole procedure has been assessed with regard to the development of green gram plants utilizing the treated wastewater exhibiting effective plant growth. The overall feasibility of the research presented here provides the opportunity to apply chemically synthesized BMF acts as superior photocatalyst for pollutants from particles in practical applications related to wastewater treatment and other applications in daily life. Using degraded water yields productive plant growth.
