Deskripsi
In current work, a magnesium oxide nanocatalyst was synthesized via greener route using aloe-vera plant leaf extracts as a reducing and stabilizing agent to construct MgO nanoparticle. The synthesized nanocatalyst has been characterized by UV–visible spectroscopy, FT-IR spectroscopy, TEM, and SAED. Further, magnesium oxide nanoparticles used as a catalyst for the efficient and facile green synthesis of various benzopyran derivatives (4a-i) in good to outstanding yields (89–94%) under microwave irradiation. This catalyst has showed good characteristics in terms of amount, recoverability, activity and reusability without noticeably degrading performance.
