“…These transition metal oxide nanoparticles can show unique chemical and physical properties due to their limited particle size (0-100 nm) and larger edge surface sites. [22] Various researcher has synthesized a larger number of transition metal oxides via using different techniques such as zinc oxide (ZnO), [23] nickel oxide (NiO), [24] ferric oxide (Fe 2 O 3 ), [25] tin oxide (SnO 2 ), [26] titanium dioxide (TiO 2 ), [27] and cobalt oxide (Co 3 O 4 ). [28] To date, TiO 2 is now regarded as the most promising photocatalyst for organic pollutant degradation because of its outstanding electrical and optical characteristics, nontoxicity, high chemical stability, friendliness to the environment, and low cost.…”

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 μm. 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.
