In recent years, there has been observed a growing need for novel, multifunctional materials that would not only replace, but also heal the damaged tissues. In this paper, the titanium dioxide films manufactured by anodic oxidation method are investigated. The study of their structurization and antimicrobial properties of the coatings is presented. Samples anodized in water solutions of ethylene glycol exhibited various character -from structurized to porous ones. As the study revealed, all samples acted anti-adhesive in terms of bacterial (Escherichia coli) and fungal (Candida albicans) surface colonisation.

Nanotube structured TiO2 on Ti surface were prepared in ethylene glycol (Ti/TiO2NTEG) medium by anodic oxidation method with different times and then the plates were calcinated at different temperatures. Non-nanotube structured Ti/TiO2, prepared by thermal oxidation method, and nanotube structured TiO2 on Ti plate in hydrogen fluoride solution were also prepared for comparison. Pt loaded Ti/TiO2NTEG photoanodes were also prepared by cyclic voltammetry method with different cycles and the optimum loaded Pt amount was determined. Photoanodes were characterized by using X-ray Diffraction (XRD), Scanning Electron Microscopy-Energy-Dispersive X-ray Analysis (SEM-EDX), and photocurrent methods. XRD analyses proved that almost all TiO2 is in anatase phase. SEM analyses show that nanotubes and Pt nanoparticles on nanotube surface are dispersed quite homogeneously. The longest nanotubes were obtained in the ethylene glycol medium and the nanotube length increased by increasing applied anodic oxidation time. In addition, a linear correlation between nanotube length and XRD peak intensity was found. Moreover, SEM-EDX and XRD analyses evidence that Pt nanoparticles on nanotube surface are metallic and in cubic structure. Photoelectrocatalytic degradation of paraquat was performed using the prepared photoanodes. Moreover, electrocatalytic and photocatalytic degradations of paraquat were also investigated for comparison, however lower activities were observed. These results evidence that the photoanodes show a significant synergy for photoelectrocatalytic activity.

Nano-titanium dioxide photocatalyst were prepared under anodizing in the ionic liquid [Bmim ]BF4, with the Sulfuric acid and water as solvent, groped for the amount of ionic liquid doping in electrolyte. With the help of XRD and SEM technology we characterized the light catalyst that we have prepared. By oxidation degrading LuoDanMing B, we tested its light catalytic activity. The results show that: the best current up time using anodic oxidation method for the preparation of TiO2/Ti catalyst is 10 min, while the light catalytic activity of the catalyst is the best; the best doping quantity of ionic liquid in electrolyte is 0.5 mL, while the light catalytic activity of the catalyst is the best; in the membrane of the titanium dioxide crystals both Rutile and Anatase are more; the mixed effect of Rutile and Anatase is better. Besides, the membrane surface is rough and porous. Therefore, the catalytic activity is higher.
