Here, we describe a simpler-sustainable approach for fabricating photo-active magnetite nanoparticles (Fe 3 O 4 -NPs) using an almost inert waste material known as red-colored iron oxide dust (IOD). The synthesized heterogeneous catalyst Fe 3 O 4 -NPs showed photoactivity in the presence of sunlight and was used for photodegradation of a higher concentration (∼1000 mg L −1 ) of noxious nitrophenols and their mixtures in an aqueous medium. Kinetic studies, including control tests, have been performed to compare the photocatalytic performance of Fe 3 O 4 -NPs vs IOD in sunlight and artificial bulb light. The half-life and percentage of photodegradation strongly suggest that sunlight influences the faster rate of photodegradation of nitrophenols and their mixtures. Radical trapping experiments were performed to identify the reactive active species responsible for the photodegradation, and the results support the significant involvement of hydroxyl radicals along with holes. Further, the real-life assessment of Fe 3 O 4 -NPs as a photocatalyst was explored by checking its photodegradation capability in industrial wastewater and soil samples via the external spiking of nitrophenols. Moreover, the results are compared with two commercially available samples of Fe 3 O 4 , which showed almost comparable results, and in the case of trinitrophenol (TNP) and the mixture, synthesized Fe 3 O 4 -NPs showed slightly better results. The quantitative studies of green chemistry metrics and DOZN software-based calculations supported the greener and more sustainable process of the present method for the synthesis of Fe 3 O 4 -NPs.
