Abstract
La/Ce mixed oxide nanoparticles dispersed on multiwalled carbon nanotubes have been synthesized by an easy route. This robust and efficient heterogeneous catalytic system was thoroughly characterized by IR, XRD, Raman, SEM, EDX, TEM, TGA and TPD-NH3 techniques. The synthesized material was screened for its catalytic activity by synthesizing various chromeno pyran derivatives employing eco-friendly parameters. The catalyst showed insignificant loss in catalytic activity on recyclability. Furthermore, the “greenness” of the methodology was supported within the realms of the well-defined green metrics like the atom economy, carbon efficiency; E-factor, reaction mass efficiency, overall efficiency, process mass intensity and the method exhibited a fine score.
