Abstract：

Ag/ZnO　nanocomposites　were　synthesized　and　applied　in　the　photocatalytic　ozonation　of　phenol.　Their　crystal,　textural,　morphological,　optical,　and　electrochemical　properties　were　investigated　by　XRD,　Raman,　SEM,　TEM,　UV–Vis　diffuse　reflectance　spectroscopy　(DRS),　X-ray　photoemission　spectroscopy　(XPS),　and　photoluminescence　(PL)　techniques　in　detail.　The　results　indicated　that　silver　nanoparticles　were　well　dispersed　on　the　surface　of　porous　ZnO　and　the　intimate　contacts　were　formed　at　the　Ag/ZnO　interfaces.　This　prominently　favored　the　separation　and　transfer　of　photoinduced　electrons　from　ZnO　to　Ag　nanoparticles　for　the　activation　of　ozone　to　produce　•OH　and　•O2　−.　As　a　result,　a　significant　enhancement　in　photocatalytic　ozonation　of　phenol　was　achieved　over　Ag/ZnO　catalysts.　It　also　showed　a　synergistic　effect　between　photocatalysis　and　ozonation.　©　2019　by　the　authors.　Licensee　MDPI,　Basel,　Switzerland.
