In this research, Cu2O and NiO nanoparticles supported on natural nanozeolite clinoptilolite (CP) was found to be a recoverable catalyst system for synthesis of pyrano-[3,2-c]pyridone and pyrano[3,2-b]pyran derivatives in aqueous media. The nanocatalysts were characterized by various techniques such as XRD, BET, SEM, TEM, TEM-EDS, and XPS analyses. TEM study reveals that the Cu2O and NiO nanoparticles
