Abstract

Copper oxide nanoparticles have been immobilized on the surface of clinoptilolite using Rheum palmatum L. root extract as a reducing and stabilizing agent in this work. FT–IR spectroscopy, UV–Visible spectroscopy, X-ray diffraction pattern, scanning electron microscopy, energy dispersive X-ray spectroscopy, and transmission electron microscopy have been used to characterize clinoptilolite, copper oxide nanoparticles, and copper oxide nanoparticles/clinoptilolite. Catalytic activity of the prepared catalysts was studied in the reduction of 4-nitrophenol, methylene blue, and rhodamine B in the presence of sodium borohydride in water at ambient temperature. Copper oxide nanoparticles/clinoptilolite was found to be a highly active catalyst in the corresponding reactions. In addition, copper oxide nanoparticles/clinoptilolite can be recovered and recycled several times with no appreciable loss of catalytic activity.
