Content of review 1, reviewed on October 05, 2022

  1. The author strongly mentions the novelty of the paper in the comparison to other research based Ag doped ZnO like
    a. Biosynthesis of ZnO and Ag doped ZnO nanoparticles from Vitis vinifera leaf for antibacterial,b. photocatalytic application
    Photocatalytic properties of Ag@Ag-doped ZnO core-shell nanocomposite
    Fabrication of highly porous ZnO/Ag2O nanoparticles embedded in N-doped graphitic carbon for photocatalytic degradation of tetracycline.
  2. XPS analysis should to show the presence of Ag and oxidation state
  3. The bandgap should be calculated and Band diagram should represent to show the enhancement of Photocatalytic.
  4. The author should rewrite the mechanism based on the calculated bandgap.
  5. Author mentioned in XRD that the Ag nanoparticles aggregate on the surface, but HRTEM results did not show any nanoparticle aggregation.
    6.

Minor revision
1. The author should deconvolute the XPS of oxygen
2. Author should plot both pure and doped XPS plot and then explain why their is no shift as mentioned in the manuscript. Refer and cite the fellow journals
