Recent advances in morphologically controlled synthesis of graphene oxide-based nanocomposite as catalyst and fuel additive

Nanocomposites become very important because of their reduce size (1-100 nm), large surface area, excellent optical magnetic, and electrical and mechanical properties. In many applications, graphene oxide-based metallic nanocomposites emerged as an outstanding class of nanomaterials that are used for different applications. (GO-ZnO) nanocomposite has gained more importance in recent years. The present research study is designed to synthesize nanocomposites and aims to monitor its characteristics and applications. Graphene oxide is synthesized by Hummers' method. Metal salts are used as precursor source of respective metal oxides. Wet chemical synthesis method such as solvothermal/hydrothermal and copreciptation processes is used because of its low cost and easy applications as compared with other processes used in the past, which have been costly and difficult to handle. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques are used to discriminate GO-Zinc oxide metallic nanocomposites. XRD is used to investigate the crystal structure, and SEM images showed that the synthesized GO/ZnO nanocomposites is irregular in shape with merged surfaces and the size is 100 nm(-1) mu m. The dark and light color shows hollow morphology of the nanocomposites, and particles are merged with each other and irregular in shape. The obtained data are statistically analyzed by using regression analysis for the further interpretations. VESTA, MATCH, Origin pro is used for the interpretation of XRD results of synthesized nanocomposites. Applications of metallic (GO/Zn) nanocomposite as catalytic activity and colorimetry, flash point, fire point, cloud point, pour point, specific gravity, and viscosity and for the degradation of Drimarene Red K-4BL is performed.

Automated summary

Nanocomposites, including metallic nanocomposites such as GO-ZnO, have gained significant importance due to their small size, large surface area, and excellent properties in fields including optics, magnetism, electricity, and mechanics. This study focuses on the synthesis and analysis of nanocomposites, using wet chemical synthesis methods such as solvothermal/hydrothermal and coprecipitation. The characterization of GO-ZnO nanocomposites is done with SEM and XRD techniques. The irregular shape, merged surfaces, and size of 100 nm(-1) mu m are observed in the synthesized GO/ZnO nanocomposites. Additionally, the applications of metallic nanocomposites, such as catalytic activity and colorimetry, are explored.
