In this paper, we report the synthesis of ZnFe2O4@SiO2@n-pr@PYD-Ni 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, SEM, FT-IR, X-ray elemental mapping, TGA, and VSM analyses. The prepared magnetic nanoparticles exhibit excellent catalytic activity in synthesizing polyhydroquinoline derivatives under green conditions
