The nanoporous framework of a cyclodextrin nanosponge was used as catalyst for accelerating the one-pot, three-component reaction of dimedone, aldehyde, and phenols for synthesis of xanthene derivatives. Moreover, the nanocavities of cyclodextrin nanosponges were exploited for immobilization of heteropolyacids through the wet impregnation method. This catalyst exhibited superior catalytic performance
heterogeneous catalysts there is a noticeable range of reactions that are catalyzedefficiently by TiO2 NPs. Moreover, carbon nanotubes (CNTs) as a support can be used to obtain nanoparticles with modified morphology, structural, chemical, electrical, and optical properties. The catalytic activity of titaniumdioxidesupported on carbon nanotubes has been greatly improved. MATERIALS AND METHODS The
