In　this　present　study,　Ag-hybridized　ZnO　was　prepared　through　a　powder-sol　method　first,　then　Ag/ZnO-AC　(activated　carbon)　composite　was　synthesized　by　a　adsorption　method　using　Ag/ZnO　and　AC　as　precursors.　The　structure　and　morphology　of　as-prepared　samples　were　characterized　by　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　Fourier　transform　infrared　spectrum　(FT-IR),　Raman　spectra,　and　diffuse　reflectance　absorption　spectra,　respectively.　The　photocatalytic　performances　of　the　prepared　catalysts　were　investigated　by　photocatalystic　degradation　of　methyl　orange.　The　influences　of　initial　pH　value,　initial　dye　concentration　and　the　calcination　temperature　on　the　photocatalytic　activity　of　the　catalysts　were　investigated　and　the　results　were　discussed.　Comparing　with　pure　ZnO　and　ZnO-AC,　Ag/ZnO-AC　composite　showed　greatly　enhanced　photocatalytic　activity.　The　results　demonstrate　that　the　hybridization　of　silver,　activated　carbon　and　ZnO　can　significantly　improve　the　photocatalytic　activity　of　ZnO.　This　work　could　provide　new　insights　into　the　fabrication　of　noble　metal/ZnO-carbon　based　composites　and　facilitate　their　application　in　environmental　protection　issues.
