Abstract
Abstract In this study, Fe 3 O 4 nanoparticles were deposited on graphitic carbon nitride (g‐C 3 N 4 ), which was subsequently functionalized with sulfonic acid groups, resulting in a magnetically separable solid acid catalyst. The synthesized catalyst was comprehensively characterized using FT‐IR, EDX, XRD, TEM, VSM, elemental analysis, and acid–base titration to assess its structural properties, surface morphology, and acidity. Its catalytic performance was evaluated in the ring‐opening reaction of epoxides with alcohols, demonstrating excellent substrate versatility and efficiency for the alcoholysis of various epoxides. The inclusion of Fe 3 O 4 nanoparticles enabled facile recovery of the catalyst using an external magnet. Furthermore, the catalyst exhibited remarkable reusability, maintaining consistent activity over four successive reaction cycles with negligible performance decline.
