“…Other major advantages of the synthetic protocol are good yields, easy catalyst handling, shorter reaction times, and high stability of the catalyst along with simple work-up processes, making it a sustainable and economical method. 87 A green and economical method from the industrial aspect has been developed where magnetic Fe-C-O-Mo nano-rods have been synthesized from waste metal precursor (a cheap screw) by a new and efficient top-down protocol (Fig. 6).…”

“…One efficient way to overcome the problem of separation and isolation is the heterogenization of active catalytic molecules, creating a heterogeneous catalytic system. [ 3–5 ] This can be achieved by nanocatalysis. Organocatalysts are normally found to be homogeneous, but although changed into nanocatalysts, they may own heterogeneous catalytic behavior.…”

Mesoporous, highly temperature resistant, magnetically separable, bimetallic, and organic‐based photoluminescent nanocatalyst has been prepared. Chitosan can act efficiently as a support material for preparing nanocatalysts. Hybrid ceria, that is, iron‐doped‐cerium oxide (Fe@CeO2), was prepared via coprecipitation method. Chitosan–iron‐doped‐ceria nanocomposite was prepared and kept in a solution of NiCl2 to adsorb Ni2+ ions, which were then reduced with NaBH4 to accumulate nickel nanoparticles. The characterization of nanocatalyst was performed using different techniques such as X‐ray diffraction (XRD), field emission scanning electron microscopy (FE‐SEM), high‐resolution transmission electron microscope (HR‐TEM), energy dispersive X‐ray spectra (EDX), Brunauer–Emmett–Teller (BET), X‐ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA) analysis. The catalyst was found to have a very small size about 2–3 nm and having a large surface area of about 121 m2 g−1, which was stable up to 800°C. It was also found to be photoluminescent. The catalyst thus prepared is useful for the reduction of nitroarenes, which is a toxic compound that is often found as a pollutant in the environment, to anilines, key intermediates for the fine chemical, agrochemical, and pharmaceutical industries. Also, nanocatalyst was used for the synthesis of various substituted tetrahydrobenzo[b]pyrans, which is an essential structural component in various natural products, in good to excellent yields.

Molecules that contain polyhydroquinoline structural scaffolds are N‐containing heterocycles which are of great interest to organic chemists and biologists. Polyhydroquinoline structural scaffolds which are known as calcium channel blockers have emerged as one of the most important class of drugs used for the treatment of cardiovascular and Alzheimer's diseases. Besides, recovery and reusability of catalysts are important issues to be discussed in modern catalysis research especially in organic synthesis. The concept of magnetically recoverable catalysts has been rapidly developed in recent times. Magnetic separation is an efficient strategy for the rapid separation of catalysts from the reaction medium. Also, an alternative to time‐, solvent‐, and energy‐consuming separation techniques. In this review, we focused on the fabrication, surface‐modification and characterization of nanomagnetic materials and their application, as magnetically recoverable catalysts, in the synthesis of polyhydroquinoline structural scaffolds.
