In this research, we reported Fe3O4@SiO2@NCs@Al2O3 [FSNCA] nanoparticles as an efficient catalyst for the synthesis of Tetrahydrobenzopyrans (THBPS) in water solvent at room temperature with short reaction time. The catalyst exhibits excellent catalytic activity, selectivity, and recyclability. The nanocatalyst structure was characterized by FT-IR, SEM, XRD, TGA, VSM, and EDS. There are significant advantages of […]
