“…The enhancement is the result of a synergistic effect between g‐C 3 N 4 and TiO 2 , which improves light absorption and the effective separation of photogenerated electron–hole pairs, as previously discussed. Other examples involve the use of GR nanosheet–TiO 2 composites, TiO 2 −Bi 2 WO 6 and TiO 2 −Al 2 O 3 films, or CdSe quantum dot/GR/TiO 2 nanosheet composites …”

The conversion of sunlight into chemical energy by using photosynthetic machinery is at the heart of nature and life. Scientists have also learned to use light energy to promote a great variety of chemical reactions, most of which are based on redox processes involving electron‐transfer steps. Indeed, the area of photoredox catalysis has recently emerged as one of the hottest fields in synthetic chemistry. Many of the photoredox reactions discovered so far take place in homogeneous phases, and rely on the use of soluble photoresponsive catalysts. However, in recent years, there have been many advances in the area of heterogeneous photocatalysis, most of which are based on the use of semiconductor materials, such as TiO2, as a key photocatalytic system. These technologies have found different applications, especially in the field of sustainable chemistry and therapy. Herein, some of these applications, and the potential of TiO2‐based photocatalysts in biology and biomedicine, are reviewed.

“…Modification TiO 2 to enhance the photocatalytic activity is of interest and doping TiO 2 with nonmetal or transition metal ion or with noble metal is widely adopted to shift the absorption edge to visible region and to improve the separation of photogenerated electron-hole pair. Barajas-Ledesma et al, have reported decrease of band gap energy on doping anatase and rutile TiO 2 films with Al 2 O 3 by electrophoretic deposition [5] and the prepared films inactivate bacteria under visible light [6]. Adsorption plays an important role in the photocatalytic process and Al 2 O 3 /TiO 2 nanocomposites have been synthesized to improve the photocatalytic mineralization by TiO 2 [7,8] or to fabricate pilot plant for adoption of photocatalysis technology for effluent treatment by industries [9,10].…”

“…The doping of titanium is performed typically by inserting impurities like N, Nb, Zr, Ta, Al, Cr and V, into the titanium crystal structure. (Archana et al, 2010;Barajas-Ledesma et al, 2010;Cantau et al, 2010;Choi et al, 2010;Czoska et al, 2011;Darriba et al, 2009;Huang et al, 2010;Khaleel et al, 2010;Martin et al, 2006;Shaama, 2005) Substantial progress has been made in understanding adhesion process on surfaces after or while immersed in liquids. In these research a number of developed techniques such as, X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), ellipsometry, fourier transform infrared attenuated total reflectance (FTIR/ATR), quartz crystal microbalance (QCM), surface plasmon resonance (SPR), dual polarization interferometry, total internal reflectance fluorescence (TIRF), voltammetry and electrochemical impedance spectroscopy (EIS) have been deployed.…”
