“…The orientation factor f = 1 means the complete orientation growth of the (hkl) direction; on the other end, complete random state is shown by f = 0. 22) The values of f (004) for as-deposited TiO 2 film and the top TiO 2 layer on the double-layer film are calculated to be 0.07 and 0.92, respectively. That is, the TiO 2 film shows nearly random growth, while TiO 2 layer of the double-layer film shows nearly complete (004) c-axis orientation growth.…”

Nanocrystalline double-layer film of TiO 2 /ZnO was prepared by pulsed laser deposition on quartz substrate and their microstructure, optical property and photocatalysis were investigated. The first/bottom ZnO layer grew on its [001] direction of the wurtzite structure, while the second/top TiO 2 layer consisted of nanorods grown on the [001] direction of its anatase structure. The TiO 2 /ZnO film showed improved photoabsorption in visible light in the UVvisible absorption spectrum; and showed weaken UV emission and enhanced deep level emission in the photoluminescence spectrum. By the degradation of methyl orange and methylene blue, the TiO 2 /ZnO film exhibited evident enhanced photodegradation efficiency in a wide wavelength range. That can be explained by the enhanced wavelength response in visible range, more effective use of irradiation light and the retarded recombination of electronhole pairs in the double layer films.

“…Many methods have been reported for the production of nanoparticles of TiO 2 , such as chemical decomposition in solution (CSD) [43], chemical vapor decomposition [72], sol-gel method [109,148], ultrasonic irradiation [109], thermal and hydrothermal ethanol [35,143], hydrothermal and solvothermal methods [7,82,137], and direct oxidation methods [149], among others. Various polar and nonpolar solvents have been used in these processes, which generally require high calcination temperatures (above 450°C) to form a regular crystalline structure (anatase).…”

Nanoparticles of titanium dioxide (TiO 2 ) have unique properties in creating an appropriate microenvironment for immobilizing biomolecules without loss of biological activity, and facilitating electron transference between the enzyme and surface of the electrode. TiO 2 properties have led to its intensive use in building electrochemical biosensors. Another aspect is, the chemical process of sol-gel which offers new and interesting advantages in the encapsulation of biomolecules sensitive to heat and environmental conditions (enzymes, proteins, antibodies, and cells from plants, animals and micro-organisms), mainly due to a synthesized process at low temperatures. The nanomaterials produced by sol-gel have many advantages, including chemical inertia, physical rigidity, insignificant swelling in an aqueous medium, and porosity. For this reason, electrochemical biosensors consisting of nanomaterials have been extensively investigated and used in important industrial sectors, such as, those of pharmaceuticals, health, food, agriculture, and environment. They provide real-time data, which allows the control and traceability of each of the processes involved. Biosensors are devices that consist of one element of molecular recognition (biomolecules) and one transduction element. The objective of this work is to conduct a review of electrochemical biosensors using nanoparticles obtained from the sol-gel process and their potential application to measure phenol compounds.

“…Numerous techniques have been used in the formation/fabrication of films on substrates of various materials with physical vapor deposition (PVD) [10] or chemical vapor deposition (CVD) [11]. However, large and complicated equipment is required; also these techniques can be only operated in a high vacuum condition.…”
