An effective approach to improve photocatalytic dye degradation and electrochemical properties of MoO₃ nanoparticles

This research introduces a pioneering, straightforward, and cost-efficient technique for producing molybdenum oxide nanoparticles. These nanoparticles underwent thorough characterization processes. To evaluate their effectiveness as photocatalysts, a series of experiments were carried out utilizing methylene blue as a representative pollutant and subjecting them to visible light irradiation. The findings showcased the favorable efficacy of the photocatalyst in breaking down methylene blue. Through UV–visible analysis, a bandgap value of 2.46 eV was determined. A comprehensive exploration was undertaken to gauge the impact of various factors such as dye concentration, catalyst quantity, and pH variation on the photocatalytic performance. The nanoparticles’ capacity to decompose methylene blue under visible light served as a metric for their photocatalytic prowess, resulting in a remarkable removal efficiency of 97%. These outcomes underscore the promising potential of the synthesized MoO₃ nanoparticles in serving as effective photocatalysts.
