Evaluation of Ruthenium Oxide Nanoparticles as Photocatalysts: Efficiency in Organic Dye Degradation and Environmental Impact Studies

Abstract

One of the most promising nanoscale materials for photodegradation is ruthenium oxide nanoparticles, which are abbreviated as RuO2 nanoparticles. Ruthenium oxide nanoparticles (RuO2 NPs) are promising nanomaterials for photodegradation. Several research methods have examined their size, phase study, and shape. We also examined RuO2 nanoparticle photocatalysis in rhodamine‐B (RhB) and acridine orange (AO) dyes degradation. We discovered that these nanoparticles were highly photocatalytic when exposed to UV light. This non‐toxic method uses no solvents. Analyzing synthesized RuO2 nanoparticles required FESEM, XRD, XPS (x‐ray photoelectron spectroscopy), FTIR (Fourier transform infrared), and UV‐visible spectroscopy. The newly synthesized nanoparticles were evaluated for catalytic activity by degrading RhB and AO dyes. After the first‐order reaction, kinetics determined the photocatalytic efficiency against RhB and AO dyes, which degraded at 84% and 82%, respectively. A tamarind plant study found no phytotoxicity in treated effluents. RuO2 catalysts degrade organic dyes in industrial wastewater efficiently and inexpensively. The study shows RuO2 nanoparticles as very effective photocatalysts for degrading organic dyes, exhibiting better performance than conventional materials. In addition, it assesses the phytotoxicity of RuO2 nanoparticles, offering valuable information about their environmental consequences and safety for prospective widespread application.
