Synthesis of Oval-Shaped Bi₂Al₄O₉ Nanoparticles and Their Applications for the Degradation of Acid Green 25 and as Fuel Additives

Abstract

The present study was designed to synthesize an oval-shaped bimetallic bismuth aluminate (Bi2Al4O9) nanoparticles through a solvothermal approach. The resulting structure and morphology of synthesized materials were characterized through X-ray diffraction and scanning electron microscopy. The catalytic performance of Bi2Al4O9 was investigated using acid green 25 (AG-25) as the model dye. The effect of various parameters like catalyst dose, H2O2 concentration, and temperature on dye degradation was studied. The Bi2Al4O9 nanocomposite exhibited the maximum removal of 95% within 50 min at 0.3 M H2O2 concentration, 0.05 mg/mL catalyst dose, and 315 K temperature. The photocatalytic removal of AG-25 followed pseudo-first-order kinetics. The thermodynamics study exposed that thermal catalytic degradation is a spontaneous, endothermic, as well as entropy-driven reaction that moves in the forward direction at the higher temperatures. The Bi2Al4O9 composite was further applied as fuel additives in order to study combustion and physical characteristics of the modified fuel. The efficacy of modified fuel was studied by investigating the fuel parameters at different Bi2Al4O9 dosages. Results revealed that synthesized NPs are excellent photocatalysts and could possibly be used for the removal of toxic pollutants.

“…A substantial proportion of textile dyes exhibit nonbiodegradable properties, and in some cases, they have been linked to potential carcinogenic effects. Consequently, it is imperative that, before discharging these charged effluents into natural water bodies, effective treatment measures are implemented to purify the wastewater. , …”
