Abstract As a result of their unique and novel properties, nanocomposites have found applications in wide variety fields. The purpose this study is to demonstrate the ability synthesize nanoparticles consisting zinc oxide (ZnO) graphene (GO) via sol–gel techniques. An x‐ray diffractometer (XRD) as well UV–visible spectrometer were used determine crystalline optical characteristics prepared samples. A hexagonal wurtzite crystal structure was observed both pure ZnO those that contain GO based on XRD results. It estimated average crystallite size broadening lines. In comparison with ZnO, antimicrobial properties enhanced when incorporated ZnO. addition, experiments absorption edge indicated presence red shift incorporation GO. When quantitative amounts, bandgap value decreased. FTIR spectra exhibit band at 486 cm −1 , which confirms Zn‐O stretching SEM images reveal random pattern structural features surface According EDX spectrum, doped 61%–64% 32%–34% oxygen, respectively. annealed higher temperature, NPs produced more H 2 narrower than before annealing. methyl blue (MB) an example organic compound order investigate potential photocatalytic addition DPPH assays, tested for scavenge free radicals.
