Fabricated Antibacterial and Bioactive Titania Nanotube Arrays Coating on the Surface of Titanium
By photic-assisted deposition, Ag nanoparticles were assembled on bioactive TiO2 nanotube arrays, which were fabricated by anodic oxidation in 0.5 wt% NH4F solution containing 0.5 wt% Na2HPO4. The samples were characterized by scanning electron mincroscope (SEM), X-ray diffraction (XRD). Germiculture experimentation was employed to testing samples’ antibacterial capability. An obvious antibacte...
متن کاملRutile phase n- and p-type anodic titania nanotube arrays with square-shaped pore morphologies.
Rutile-phase TiO2 nanotube arrays without broken walls were formed by annealing of anodically formed nanotubes in a propane flame at 650 °C and in air at 750 °C. An unusual morphological transformation was observed from the ellipsoidal pore-shapes of titania nanotubes grown in aqueous electrolyte to a square-shaped pore structure subsequent to the anneals. 750 °C annealed nanotubes were found t...
متن کاملSelf-Ordered Titanium Dioxide Nanotube Arrays: Anodic Synthesis and Their Photo/Electro-Catalytic Applications
Metal oxide nanotubes have become a widely investigated material, more specifically, self-organized titania nanotube arrays synthesized by electrochemical anodization. As a highly investigated material with a wide gamut of applications, the majority of published literature focuses on the solar-based applications of this material. The scope of this review summarizes some of the recent advances m...
متن کاملTransition from anodic titania nanotubes to nanowires: arising from nanotube growth to application in dye-sensitized solar cells.
Anodic formation of titania nanowires has been interpreted using a bamboo-splitting model; however, a number of phenomena are difficult to explain with this model. Herein, transition from nanotubes to nanowires is investigated by varying the anodizing conditions. The results indicate that the transition requires a large number of hydrogen ions to reduce the passivated area of tube walls, and th...
متن کاملTiO2 nanotube arrays fabricated by anodization in different electrolytes for biosensing
Titania nanotube arrays were fabricated by anodic oxidation of titanium foil in different electrolytes. The morphology, crystallinity and composition of the as-prepared nanotube arrays were studied by XRD, SEM and EDX. Electrochemical impedance spectroscopy (EIS) was employed to investigate their electrical conductivity and capacitance. Titania nanotube arrays co-adsorbed with horseradish perox...
