Copper Nanoparticles Decorated Alginate/Cobalt-Doped Cerium Oxide Composite Beads for Catalytic Reduction and Photodegradation of Organic Dyes

Cobalt-doped cerium oxide (Co–CeO(2)) was synthesized and wrapped inside alginate (Alg) hydrogel beads (Alg/Co–CeO(2)). Further, copper nanoparticles (Cu) were grown on Alg/Co–CeO(2) beads. Cu decorated Alg/Co–CeO(2) composite beads (Cu@Alg/Co–CeO(2)) were tested as a catalyst for the solar-assisted...

description Cobalt-doped cerium oxide (Co–CeO(2)) was synthesized and wrapped inside alginate (Alg) hydrogel beads (Alg/Co–CeO(2)). Further, copper nanoparticles (Cu) were grown on Alg/Co–CeO(2) beads. Cu decorated Alg/Co–CeO(2) composite beads (Cu@Alg/Co–CeO(2)) were tested as a catalyst for the solar-assisted photodegradation and NaBH(4)-assisted reduction of organic pollutants. Among different dyes, Cu@Alg/Co–CeO(2) was found to be the best catalyst for the photodegradation of acridine orange (ArO) under solar light and efficient in reducing methyl orange (MO) with the aid of NaBH(4). Cu@Alg/Co–CeO(2) decolorized ArO up to 75% in 5 h under solar light, while 97% of MO was reduced in 11 min. The decolorization efficiency of Cu@Alg/Co–CeO(2) was further optimized by varying different parameters. Thus, the designed catalyst provides a promising way for efficient oxidation and reduction of pollutants from industrial effluents.
