In this work, a novel composition of cadmium sulfide (CdS), copper(II) hydroxide (Cu(OH)2), copper(II) oxide nanoparticles, and chlorophyll (Chl) is prepared based on polyvinyl alc. (PVA) matrix. The characterization of the CdS/Cu(OH)2/CuO@PVA-Chl nanocomposite has been carried out by the various anal. methods. Then, the prepared CdS/Cu(OH)2/CuO@PVA-Chl is then applied as a very efficient photocatalyst for degradation of the hazardous dyes such as methylene blue (MB), Congo red (CR), and 4-chlorophenol (4-CP) in the aqueous samples. For the preparation of the intended nanocomposite, the Chl has been extracted from fresh spinach via a convenient mech. adsorption/desorption method. In the obtained optimum conditions, a great degradation efficiency (ca. 97.6%) for the MB dye achieved by simultaneous application of the prepared CdS/Cu(OH)2/CuO@PVA-Chl photocatalyst and the visible-light (LED 70 W, λ = 425 nm), over a 60 min contact time. Moreover, the degradation efficiency of the CR and 4-CP dyes were ca. 92% and 88%, resp. The reusability investigations have revealed that no significant loss in the catalytic performance is occurred over seven times recycles. As well, degradation of the pathogens by the CdS/Cu(OH)2/CuO@PVA-Chl nanocomposite has been screened under the obtained optimal conditions. Briefly, the diameter of the inhibition zones by the prepared composite film has been evaluated to be ca. 11.0 (± 0.1) and 9.0 (± 0.1) mm for S. aureus and E. coli bacterial cells, resp. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Name: Cuprichydroxide).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Copper has continued to be one of the most utilized and important transition metal catalysts in synthetic organic chemistry. Due to these characteristics, copper nanoparticles have generated a great deal of interest especially in the field of catalysis. Name: Cuprichydroxide
