X-ray diffraction patterns of all prepd. powders showed a mixed phase of Ag and ZnO.  The existence of metallic Ag on the surface of all prepd. ZnO powders was confirmed by XPS.  Their photocatalytic activities were investigated through the degrdn. of a methylene blue soln. under blacklight illumination.  The Ag/ZnO prepd. from the Zn2+ soln. contg. 7 mol% of Ag+ had the highest photocatalytic activity and this also showed better photocatalytic activity than a com. ZnO powder.

Ag-doped ZnO powders were prepd. directly from an aq. soln. of zinc acetate dihydrate and AgNO3 in the presence of poly(ethylene oxide)-b-poly(propylene oxide), (PEO)19-b-(PPO)3, and NaOH at 70°.  The ZnO powders had an urchin-like shape without any dopant and this turned to an agglomerated rod-like structure when the Ag loading was ≤0.5 mol%.  If the Ag content was further increased, the urchin-like shape reappeared.  This may occur because the Ag aggregates at the grain boundary.  The finding that the diam. of the urchin-like shape decreases as the Ag concns. increase, can be explained by the pinning effect of the Ag particles as obstacles that inhibit the grain migration and grain growth.  An increase of the photocatalytic efficiency for degrading methylene blue increases with the Ag loading up to 1.0 mol% while the best of the antibacterial activity against Staphylococcus aureus was found at 0.5-0.8 mol% of Ag.  However, the different Ag loadings in the ZnO powders had no effect on the antibacterial effect on Escherichia coli.
