Organic pollutants are the largest kind of pollutants released into waters and wastewater from the some industry and industrial processes. Photocatalytic degradation is one of the significant and effective methods to remove the dyes and other organic pollutant from water and wastewater. This mini-review presents the application of zinc ferrites and ZnFe2O4-based composites in the photocatalytic degradation of organic dye. The zinc ferrite nanomaterials are obtained mainly by thermal methods, sol-gel, co-precipitation, and solid-state or hydrothermal route. Zinc Ferrites have good photocatalytic activity, but when exploited as composite photocatalysts, their photocatalytic efficiency were increased. AS a critical magnetic material, the ZnFe2O4 spinel structure has been proven to be useful in removal dye, ZnFe2O4 have photocatalytic activity under visible light irradiation. However, it is possible to improve the efficiency of photocatalysis activity of ZnFe2O4 by coupling it with another semiconductor or coupling it with carbon nanotubes and graphene, resulting in enhanced photocatalytic performance.

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.

In this work, biosynthesized Fe3O4@Ni nanoparticles using Euphorbia maculata aqueous have been used as effective catalysts in the synthesis of 2,3‐disubstituted benzo[b]furan derivatives using three component coupling of aldehydes, secondary amines and alkynes (A3 coupling reaction). Using novel nanoscale materials, the current green, practical and economical method leads to short reaction times and high yields. The biosynthesized catalyst was also successfully employed in the Sonogashira cross‐coupling reactions of various aryl halides with phenylacetylene. The best performance was observed using just 20 mg of the catalyst and ethanol as a green solvent. The developed protocol provides easy workup, short reaction times and good to excellent product yields. Furthermore, since the composite is highly stable, an external permanent magnet can be easily used for separating the catalyst. Thus, the catalyst can be recycled several times without considerable loss of catalytic activity.
