Fabrication and characterization of magnetic trimetallic mesoporous nanocomposite: as an effective nanocatalyst for synthesis of bisphenol derivatives

Year: 2026

Type: article

Abstract: Hollow materials have designed with shell structures and porous cavities, as a new generation of functional materials, have shown remarkable performance in various fields. In this study, a magnetic, porous, and reusable nanocatalyst was designed and prepared. The CoNiFe 2 O 4 @C nanocatalyst was prepared through a multistep process. Initially, the magnetic trimetallic CoNiFe 2 O 4 was prepared and followed by the deposition of a SiO 2 layer to form the CoNiFe 2 O 4 @SiO 2 yolk–shell structure. The subsequent removal of the silica layer is resulted in the formation of the CoNiFe 2 O 4 @C yolk–shell magnetic nanocomposite. In this protocol, bisphenol derivatives were synthesized through a three-component reaction of aldehyde and 2-4-dimethylphenol in a ratio of 1:2 by using this prepared catalyst. The applications of bisphenols are included antioxidant, anticancer, anti-arthrosis, anti-inflammatory and antimicrobial properties. The identification of the prepared catalyst was carried out and reported using FT-IR, XRD, BET, EDS, Mapping, FE-SEM, TEM and VSM techniques. Also, the bisphenol products were identified using melting point, FT-IR, 1 H NMR analyses. The proposed approach presents multiple benefits such as; mild reaction conditions, ease of operation, reliable safety, excellent yield, effective purification of synthetic organic compounds, and minimal catalyst usage.
