Assorted common contaminants namely organic dyes and nitro compounds are generated by various industries and have caused alarming problems for the environment and humans. The development of efective and newer methods to eliminate these contaminants is imperative. One efective way to eliminate these pollutants is to deploy sustainable heterogeneous catalyst systems. Accordingly, a novel and efcient magnetic nanocomposite catalyst comprising graphitic carbon nitride (g-C3N4), gold (Au), and hematite (α-Fe2O3) nanoparticles (C3N4/Fe2O3/Au) is prepared through a cost-efective and green method. The individual components, g-C3N4 and Au nanoparticles (NPs), are prepared via thermal decomposition of urea and laser ablation in liquid, respectively. The behavior of C3N4/Fe2O3/Au nanocomposite as a catalyst for the borohydride reduction of methyl orange (MO) dye and 4-nitrophenol (4-NP) in aqueous solution, is illustrated
