Abstract A new nanocomposite of the type ZnO fence with graphene quantum dots GQD/ZnO has been synthesized by the hydrothermal method. The crystallinity, structural and morphological properties are characterized by XRD, FT-IR, Raman, FESEM, TEM, DRS and PL techniques. Interestingly, the prepared GQD/ZnO nanocomposites act as photocatalyst for the degradation of the phenol solution with a maximum of 79% under UV light irradiation. The effect of pH for photodegradation of the catalyst has also been investigated in detail. Further, the antibacterial activity of GQD/ZnO has been investigated against P. aeruginosa and the results show enhanced activity, even at low concentration.
