Herein, a novel copper-containing Fe₃O₄@Gelatin (Fe₃O₄@Gelatin-Cu) material is prepared, characterized and its catalytic activity is studied. Fe₃O₄@Gelatin-Cu was prepared through coating of natural gelatin polymer on magnetic Fe₃O₄ NPs followed by treatment with a copper salt. The characterization of Fe₃O₄@Gelatin-Cu was achieved using FT-IR, VSM, SEM, TGA, and EDX analyses. The Fe₃O₄@Gelatin-Cu was employed as a powerful nanocatalyst in the preparation of hexahydroquinolines under green conditions. The high yield of the desired products and good recoverability, reusability and stability of the Fe₃O₄@Gelatin-Cu nanocatalyst are the main advantages of this study. The combined properties of gelatin, magnetic nature and supported copper catalyst make Fe₃O₄@Gelatin-Cu a valuable material in the catalytic world.
