Sonosynthesis of pyranochromenes and biscoumarins catalyzed by Co3O4/NiO@GQDs@SO3H nanocomposite
Co3O4/NiO@GQDs@SO3H nanocatalyst has been used as an effective catalyst for the preparation of dihydropyrano[3,2-c]chromenes and biscoumarins under ultrasonic irradiations in ethanol. The catalyst has been characterized by FT-IR, XRD, SEM, EDS, BET, TGA, XPS and VSM. Atom economy, reusable catalyst,...
