Special Issue Information

Dear Colleagues,

Nanocomposites have shown outstanding performance in different areas and have therefore received remarkable attention due to their exceptional assets, characteristic behavior, and broad range of applications in different areas, particularly in medical, food, cosmetics, packaging, and the environment. These widespread applications of nanocomposites have motivated scientists all over the world to advance materials with innovative properties that cannot be met by conventional materials. Advancement of nanocomposites is a growing area and has seen markedly increased interest in recent years due to the great potential associated with this new generation of extraordinary materials. Nanocomposites possess customized assets and incomparable behaviors appropriate for a large variety of applications. These substances have extraordinary properties and are capable of different applications in a variety of areas and a generous range of useful applications. These properties are accountable for the grand progress in the many assets of polymers. In the field of composites research, different materials have been used in hopes of exploiting the unique properties of their conventional constituents, which are not obtained in one component by itself.

It is our pleasure to announce the launch of a new Special Issue on the topic of “Smart Nanocomposites for Multiple Applications” in numerous fields of high importance. We welcome papers from multiple research fields, including novel composite synthetic routes and their applications in medical, environmental, catalytic, sensors and energy storage devices, etc.

Abstract
Cobalt-doped cerium oxide (Co–CeO2) was synthesized and wrapped inside alginate (Alg) hydrogel beads (Alg/Co–CeO2). Further, copper nanoparticles (Cu) were grown on Alg/Co–CeO2 beads. Cu decorated Alg/Co–CeO2 composite beads (Cu@Alg/Co–CeO2) were tested as a catalyst for [...] Read more.
Cobalt-doped cerium oxide (Co–CeO2) was synthesized and wrapped inside alginate (Alg) hydrogel beads (Alg/Co–CeO2). Further, copper nanoparticles (Cu) were grown on Alg/Co–CeO2 beads. Cu decorated Alg/Co–CeO2 composite beads (Cu@Alg/Co–CeO2) were tested as a catalyst for the solar-assisted photodegradation and NaBH4-assisted reduction of organic pollutants. Among different dyes, Cu@Alg/Co–CeO2 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 NaBH4. Cu@Alg/Co–CeO2 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–CeO2 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. Full article

Copper oxide-antimony oxide (Cu2O-Sb2O3) was prepared and entrapped inside Na-alginate hydrogel (Alg@Cu2O-Sb2O3). The developed Alg@Cu2O-Sb2O3 was used as catalytic reactor for the reduction of 4-nitrophenol (4-NP), 2-nitrophenol (2-NP), 2,6-dinitrophenol (2,6-DNP), methyl orange (MO), congo red (CR), acridine orange (AO), methylene blue (MB) and potassium ferricyanide (K3[Fe(CN)6]). Alg@Cu2O-Sb2O3 was found to be selective and more efficient for the reduction of 2-NP among all the pollutants. Therefore, 2-NP was selected for a detailed study to optimize various parameters, e.g., the catalyst amount, reducing agent concentration, 2-NP concentration and recyclability. Alg@Cu2O-Sb2O3 was found to be very stable and easily recyclable for the reduction of 2-NP. The Alg@Cu2O-Sb2O3 nanocatalyst reduced 2-NP in 1.0 min, having a rate constant of 3.8187 min−1.
