Green Synthesis and Enhanced Photocatalytic Performance of rGO/ZnO/FeO Nanocomposites: A Sustainable Approach to Environmental Remediation.

The fast industrialization and mounting pollution have necessitated the need for advanced materials in order to degrade pollutants efficiently. Metal oxide-based and graphene-derivative photocatalytic nanocomposites are excellent for harnessing light energy in environmental remediation. Among them, ZnO-based nanocomposites have drawn considerable attention because of their high photocatalytic activity and stability.

Enhanced catalytic and antibacterial efficiency of biosynthesized Convolvulus fruticosus extract capped gold nanoparticles (CFE@AuNPs).

Scientists are interested in biosynthesis of gold nanoparticles owing to their catalytic and biological features. In this research, the extract of Convolvulus fruticosus (C. fruticosus; CFE) extract was applied to synthesize spherical-like gold nanoparticles (CFE@AuNPs).

Flower-Like CuO/ZnO Hybrid Hierarchical Nanostructures Grown on Copper Substrate: Glycothermal Synthesis, Characterization, Hydrophobic and Anticorrosion Properties.

In this work we have demonstrated a facile formation of CuO nanostructures on copper substrates by the oxidation of copper foil in ethylene glycol (EG) at 80 °C. On immersing a prepared CuO film into a solution containing 0.1 g Zn(acac)₂ in 20 mL EG for 8 h, ZnO flower-like microstructures composed of hierarchical three-dimensional (3D) aggregated nanoparticles and spherical architectures were spontaneously formed at 100 °C.

Enhanced photocatalytic degradation of dyes over graphene/Pd/TiO nanocomposites: TiO nanowires versus TiO nanoparticles.

In this study, at first, TiO nanowire was prepared by an alkaline hydrothermal process. In the following, Gr/Pd/TiO-NPs and Gr/Pd/TiO-NWs were synthesized by a combination of hydrothermal and photodeposition methods. The properties of as prepared products were characterized using XRD, FT-IR, SEM, DRS, TEM, ICP-OES, EDS and TGA analysis.

Recyclable magnetic superhydrophobic straw soot sponge for highly efficient oil/water separation.

A simple and low-cost route to fabricate durable superhydrophobic magnetic polyurethane sponge was obtained by immersing a polyurethane sponge in a colloidal suspension of straw soot and magnetic nanoparticles. The as prepared sponge was used for separation of oil/water mixture. XRD, FT-IR, VSM, SEM and contact angle measurement analysis were used for characterization the materials.
