From this method, the existence of a metallic Ag coating on the ZnO surface was confirmed by transmission electron microscope and XPS.  The photocatalytic activity of the Ag/ZnO powders was investigated by analyzing the degrdn. of an aq. methylene blue soln. under a blacklight irradn.  Furthermore, the parameters, including Ag content, catalyst loading, initial dye concn. and pH, were also studied.  After the methylene blue soln. was irradiated for 30min under a blacklight illumination, total mineralization was not obsd. as the presence of some carbon compd. species was indicated in a mass spectrum.  Furthermore, the toxicity of the treated methylene blue soln. produced by the Ag/ZnO powders was also investigated by a test for the inhibition of the growth of Chlorella vulgaris.

Hydrolysis of each phosphate salt gave a specific pH that affected the purity and morphol. of the prepd. Ag3PO4.  The Ag3PO4 prepd. from Na2HPO4 showed the best photocatalytic activity induced by visible light to degrade methylene blue dye.  During the photocatalytic process, Ag3PO4 decompd. and produced metallic Ag, and this evidence was confirmed by the X-ray diffraction technique and XPS.  The photocatalytic efficiency decreased with the no. of recycles used.  This Ag3PO4 photocatalyst also degraded another cationic dye, rhodamine B, but did not degrade reactive orange, an anionic dye.  The degraded products produced by the photocatalysis had lower toxicities than the untreated dyes using Chlorella vulgaris as a bioindicator.

Their photocatalytic activities were investigated through the degrdn. of a methylene blue soln. under blacklight illumination.

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.
