چکیده انگلیسی
The Pd/Ag/HAp nanoparticles were uniformly electrodeposited onto the whole top surface and around the tube walls, including the inner side and outer side, of the ultra-fine TiO2 nanotubes. The ordered tubular structure was well-maintained without destruction during the electrochemical deposition process. With excessive activation up to a deposition time of 7200Â s, continuous granular Pd/Ag/HAp nanoparticles gradually formed with a rough surface around the top of the TiO2 nanotube layer. From the XPS and EDS analyses, Ti, Ca, P, Pd, and Ag were detected in the nanoparticles on the electrochemically deposited surfaces. The surface morphology after soaking in SBF exhibited hydroxyapatite-like precipitates, which consisted of the four elements Ti, O, Ca, and P, and having a Ca/P atomic ratio of 1.67.
