A hybrid nanostructure comprising NiFe2O4 nanorods and 2-naphthalenesulfonic acid (2-NSA) doped polyaniline nanotubes (NiFe2O4@PANI/NSA) has been explored as an efficient catalyst for the reduction of nitroaroms. in the aqueous medium. The obtained NiFe2O4@PANI/NSA nanocomposites (NCs) were characterized using XRD, FE-SEM, HR-TEM, TGA, FT-IR, BET, and XPS, and their catalytic efficiencies were investigated for the reduction of nitroarenes with 4-nitrophenol (4-NP) being used as a model nitroarene. NiFe2O4@PANI/NSA exhibited excellent catalytic activity with a rate constant of 0.00557 s-1 and excellent recyclability, with the identical activity being retained after 15 successive runs. The mechanism of the reaction was proposed based on the kinetics results using the Langmuir-Hinshelwood model. The activation energy (Ea) was calculated to be 30 kJ/mol-1 for 4-NP reduction In the experiment, the researchers used many compounds, for example, 3-Hydroxy-6-methyl-2-nitropyridine (cas: 15128-90-2Name: 3-Hydroxy-6-methyl-2-nitropyridine).
3-Hydroxy-6-methyl-2-nitropyridine (cas: 15128-90-2) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Name: 3-Hydroxy-6-methyl-2-nitropyridine
