In this work, a fast, environment-friendly and economic route was used to prepare ZnO their nanocomposites containing reduced graphene oxide (RGO) carbon nanotubes (CNTs) for the fabrication of dye-sensitized solar cells (DSSCs). The prepared nanostructures were well-characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission (TEM), Raman measurem...

Lithium-ion batteries have made significant commercial and academic progress in recent decades. Zinc oxide (ZnO) has been widely studied as a lithium-ion battery anode due to its high theoretical capacity of 987 mAh g-1, natural abundance, low cost, environmental friendliness. However, ZnO suffers from poor electronic conductivity large volume variation during the discharge/charge process, lead...

A novel CuZnO multicomponent catalyst, involving reduced graphene oxide (rGO) as a support, was synthesized to be applied in the catalytic hydrogenation of CO 2 methanol. The CuZnO@rGO composite prepared 3D aerogel by two-step process supercritical for macrostructuration and H treatment reduction. Electron microscopy visualize meso/macroporous morphology formed drying. elemental mapping depicte...

Although several studies have explored the rGO-ZnO nanocomposites gas sensing properties towards many gases, only a few are devoted to ozone detection. This paper explores novel synthesis procedure of based upon two-step physical process. Namely, reduction process GO carried out using UV laser radiation followed by deposition ZnO nanoparticles on rGO surface RF-magnetron Sputtering. Our results...

The application of heterogeneous photocatalysis in industrial scale has been hindered by a lack of simple mathematical models that can be easily applied to reactor design and scale-up. This work intends to use a simple mathematical model for predicting methylene blue (MB) degradation in a slurry-annular photocatalytic reactor using zinc oxide (ZnO) hybridized with reduced graphene oxide (rGO)-Z...

Abstract Production of a ZnO–rGO composite, using novel one-pot method consisting in continuously flowing argon into GO aqueous suspension heated at 80 °C, the presence galvanized iron steel scrap is presented. FTIR shows complete disappearance functional groups and only C=C band remained, indicating extensive reduction. Raman spectra indicated sp 2 character increase after reaction E 2h mode Z...

Nanomaterial-based catalytic conversion of hazardous organic pollutants into benign substances is one the green methods employed for wastewater treatment. This study demonstrates fabrication (rGO-ZnO)/CuO nanocomposites (NCs) via a microwave (MW)-assisted method (photo)catalytic application. The crystal structure, optical, morphological, and electrochemical characteristics were examined using X...

A novel sensitive and selective ZnO/Co 3 O 4 /rGO nanocomposite was fabricated using a hydrothermal method used as non-enzymatic electrochemical sensor for the detection of glucose.

Correction for ‘Solar-assisted all-solid supercapacitors using composite nanostructures of ZnO nanowires with GO and rGO’ by Cigdem Tuc Altaf et al. , J. Mater. Chem. C 2022, 10 10748–10758, https://doi.org/10.1039/D2TC02114E.

Spurred by controversial literature findings, we enwrapped reduced graphene oxide (rGO) in ZnO hierarchical microstructures (rGO loadings spanning from 0.01 to 2 wt%) using an situ synthetic procedure. The obtained hybrid composites were carefully characterized, aiming at shining light on the possible role of rGO claimed increased performance as photocatalysts. Several characterization tools ex...
