Formation and bioactivity of porous titania containing nanostructured Ag

In this work, porous titania were prepared on bulk Ti via chemical oxidation, and then nanostructured Ag was deposited on the surface of titania by ion beam sputtering. After annealing treatment, the nanostructured Ag titania were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), electron probe micro-analyzer (EPMA), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). The influence of nanostructured Ag on the morphology, grain growth, phase transformation, and bioactivity of titania was investigated.
