Scholarcy highlights

  • The present study investigates the photocatalytic degradation of 2,4-Dichlorophenoxyacetic acid, a hazardous herbicide using TiO2/Graphene oxide nanocomposite photocatalysts
  • The nanocomposite photocatalysts were synthesized via solvothermal method by varying the weight percentage of graphene oxide
  • The nanocomposite photocatalysts were examined by X-ray diffraction, scanning electron microscopy, Brunauer Emmet Teller adsorption isotherm, Fourier-transform infrared and UV–visible-diffuse reflectance spectroscopy analysis
  • The XRD pattern of nanocomposite was found unaltered, whereas a significant change around 33–91% was observed in the surface area of nanocomposites as compared to the pristine TiO2
  • This study offers a better platform for the synthesis of new composite photocatalytic materials for environment abatement by the degradation of organic pollutants
