“…Notably, the exact mechanism for the one-pot reductive acetylation reaction of nitroarenes in the presence of CuFe 2 O 4 as a simple and efficient promoter is not known. But, based on our observations and literature survey [71,74,75], a plausible reaction mechanism for this reaction is presented in Scheme 2. Firstly, nitroarene and hydrogen which is obtained from the reaction of NaBH 4 and water absorbed on the surface of CuFe 2 O 4 NPs.…”

Two simple, efficient, and environmentally benign protocols for the synthesis of various N-arylacetamides via N-acetylation of arylamines and straightforward one-pot reductive acetylation of aromatic nitro compounds promoted by CuFe2O4 nanoparticles in water at reflux have been developed. The prepared CuFe2O4 MNPs are well known and fully characterized by various techniques. Furthermore, the CuFe2O4 NPs easily separated from the reaction environment using an external magnetic field and can be reused for several times without significant loss of its activity for both mentioned reactions.

“…The CuFe 2 O 4 nanoparticles showed tremendous catalytic performance with high recyclability using NaBH 4 as a reducing agent. 26 , 27 The catalytic activity of CuFe 2 O 4 was enhanced using graphene as a support which was attributed to the synergistic effect of copper ferrite and graphene. The magnetically separable NiFe 2 O 4 @Cu displayed excellent activity as a catalyst for reduction of nitroarenes to their corresponding amines.…”

As industrialization progresses, there is a large release of hazardous pollutants into the environment. These pollutants, which contain nitro compounds and organic dyes, are extremely dangerous due to their toxic and carcinogenic nature. An efficient, environmentally benign, and economical catalyst to degrade environmental pollutants or convert them into useful products has been of sustained interest in recent years. In this context, we report a simple and inexpensive combustion fabrication of NiCrFeO 4 using different fuels such as glycine, polyvinyl alcohol (PVA), and urea, showing tremendous catalytic and photocatalytic functionalities. Rietveld refinement and X-ray diffraction studies confirmed the formation of single-phase ferrites, with crystallite sizes ranging from 3.9 to 43.31 nm. The values of optical band gap, obtained from the diffused reflectance spectroscopy technique, lie in the visible region range (1.50–1.60 eV), and hence, all the synthesized ferrites can act as good photocatalysts in the presence of visible light. All the NCF nanocatalysts were utilized for the reduction of nitroarenes and photocatalytic degradation of various cationic (RhB and MB) and anionic (MO) dyes and their mixture. NCFP displayed excellent activity for the reduction and oxidation reactions owing to its large surface area and low optical band gap. Furthermore, the photo-oxidative degradation by NCFP was also enhanced due to its low recombination of charge carriers as confirmed by the photoluminescence (PL) spectroscopy. NCFP efficiently reduces nitrobenzene to aminobenzene with 95% yield using sodium borohydride as the reducing agent in methanol medium at RT in 10 min. The results of photocatalytic activity have shown that the degradation efficiency of NCFP follows the order RhB > MB > MO in their unitary solution. Furthermore, in the case of the mixture of dyes, NCFP showed enhanced photocatalytic degradation for cationic dyes (RhB and MB) compared to that of anionic dye (MO). From the performance point of view, this catalyst can be useful in industrial application because of its high stability, greater catalytic efficiency, and cost-effectiveness.
