“…Then, Ag metal play an important role in capturing electron that act as electron trap. This phenomenon also agreed with previous study [48]. The Schottky barrier that develop between TiO 2 and Ag metal enhance the electron lifetime and provide more time for electron and hole to react with the targeted contaminants [49].…”

Mixed anatase/rutile Ag doped titanium dioxide (TiO 2 ) film successfully fabricated with two simple step. Firstly, Ag doped rutile phase TiO 2 was fabricated by hydrothermal method at low temperature of 150°C for 10 hours and followed by various duration of immersion in tayca 320 solution for anatase phase. The various duration of immersion was studied to investigate the optimum time immersion to decorate anatase phase on Ag doped rutile phased TiO 2 film in assisting photocatalytic activity. The prepared samples were analyzed for their crystalline structure, morphology, composition, and photocatalytic activity using various analytical techniques such as X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDX) and methylene blue (MB) degradation. It was observed that mixed phased of Ag doped TiO 2 film shows an excellent photocatalytic activity compared with the single phase. The optimum immersion time is 1 hour. The photodegradation of 1 hour immersion film was reached 100 percent degradation only for 90 minutes and increased up to 19% compared with no anatase phase film. It was proved that mixed phases has better degradation compared with single phase. The anatase phase helps to avoid recombination between electron and holes pair by capturing the electron and enhanced the photocatalytic activity since the anatase decorated on smooth surface of the rod which is no active area for photocatalytic activity.

“…: 21-1272). The diffraction peak of Ag is seen at 38.2 0 , 44.4 0 and 64.6 0 at crystal plane (111), (220) and (220), matched with JCPDS card of Ag (No.04-0783) [20], in line with Akgun & Duruchan, who reported that the addition of small amounts of Ag into TiO2 thin films resulted in the presence of anatase and rutile phases along with two extra peaks of Ag at 38.2˚ and 44.4˚ [21]. It can also be seen that additional GIXRD peaks that correspond to the Ag area are clearly defined in the pattern.…”

Ag/TiO2 thin films were prepared using the sol-gel spin coating method. The microstructural growth behaviors of the prepared Ag/TiO2 thin films were elucidated using real-time synchrotron radiation imaging, its structure determined using grazing incidence X-ray diffraction (GIXRD), its morphology imaged using the field emission scanning electron microscopy (FESEM), and its surface topography examined using the atomic force microscope (AFM) in contact mode. Cubical white spots were detected, identified as Ag, while the TiO2 thin film resembles a porous ring-like structure with each ring coalescing and forming channels. Junction growth is directly proportional with time under continuous heating conditions (annealing), and its growth orientations and patterns were seemingly random.

Functionalized Mesoporous Thin Films for Biotechnology

Mesoporous materials bear great potential for biotechnological applications due to their biocompatibility and versatility. Their high surface area and pore interconnection allow the immobilization of molecules and their subsequent controlled delivery. Modifications of the mesoporous material with the addition of different chemical species, make them particularly suitable for the production of bioactive coatings. Functionalized thin films of mesoporous silica and titania can be used as scaffolds with properties as diverse as promotion of cell growth, inhibition of biofilms formation, or development of sensors based on immobilized enzymes. The possibility to pattern them increase their appeal as they can be incorporated into devices and can be tailored both with respect to architecture and functionalization. In fact, selective surface manipulation is the ground for the fabrication of advanced micro devices that combine standard micro/nanofluids with functional materials. In this review, we will present the advantages of the functionalization of silica and titania mesoporous materials deposited in thin film. Different functional groups used to modify their properties will be summarized, as well as functionalization methods and some examples of applications of modified materials, thus giving an overview of the essential role of functionalization to improve the performance of such innovative materials.
