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.

通过水热法合成了具有石墨烯量子点GQD / ZnO的新型ZnO栅栏纳米复合材料。通过XRD，FT-IR，拉曼，FESEM，TEM，DRS和PL技术表征了结晶度，结构和形态特性。有趣的是，制备的GQD / ZnO纳米复合材料可作为光催化剂，在紫外光照射下降解苯酚溶液，最大降解率为79％。还已经详细研究了pH对催化剂光降解的影响。此外，已经研究了GQD / ZnO对铜绿假单胞菌的抗菌活性，结果表明即使在低浓度下其活性也增强。
