Herein, we report the synthesis of ZnFeO@SiO@L-lysine@SOH as a green, novel magnetic nanocatalyst, containing the sulfuric acid catalytic sites on the surface of zinc ferrite as the catalytic support. The physical and chemical properties of raw and modified samples (ZnFeO@SiO@L-lysine@SOH) were characterized by TGA, EDX, PXRD, Map, and FTIR analyses. The prepared nanocatalyst has excellent catalytic activity in synthesizing the oxidation of sulfides to the sulfoxides and Synthesis of pyrazolyl (Bis(pyrazolyl)methane) derivatives under green conditions.

Herein, we reported an efficient and novel metal-organic framework (MOF) that was designed and fabricated via hydrothermal reaction of chromium(III) nitrate nonahydrate salt with EDTA as an organic ligand. The prepared MOF was investigated by PXRD, BET, SEM, EDS, FT-IR, and X-ray mapping techniques. N adsorption-desorption isotherms indicated excellent BET surface area for Cr-EDTA-MOF, which is 234.

In this paper, we report the synthesis of ZnFeO@SiO@APTES@DHBS-Cu as a novel magnetic nanocatalyst, in a mild and green environment. The structure of the described magnetic compound was characterized by different physicochemical techniques including XRD, EDS, AAS, SEM, FT-IR, X-ray elemental mapping, TGA, and VSM analyses. The prepared magnetic nanoparticles exhibit excellent catalytic activity in synthesizing bis (pyrazolyl)methanes and oxidation of sulfide derivatives under green conditions.
