“…Nakano et al [23] reported visible light photocatalytic activity of of oxygen deficient TiO 2 films obtained by Ar/H 2 plasma surface treatment; Dong et al [24] anodization for visible light photocatalysis; Lee et al [26] grew N-doped TiO x films using reactive sputtering reporting a red-shift band gap; and Leichweiss et al [20] grewn highly nonstoichiometric TiO x thin films, that shown high efficiency for water splitting reaction, using pulsed laser deposition at room temperature. Related to the activation of TiO 2 by infrared radiation, we only found the work of Gannoruwa et al [28], they reported that the nanocomposite Ag 2 O/TiO 2 was infrared active in the range from 800 nm to 1200 nm. To the best of our knowledge, there is not any report to date about infrared radiation photocatalytic activity of TiO x thin films, which is the subject of the present paper.…”

“…Sulfides such as MoS 2 or In 2 S 3 have been used in this context [ 106 , 107 ]. Regarding oxides, we can highlight the cases of Ag 2 O [ 108 ], and WO x [ 109 , 110 ]. These systems and particularly the latter are real, full-spectrum catalysts, with utilization of the UV-visible-nearIR electromagnetic range.…”

Photo-catalysis is a research field with broad applications in terms of potential technological applications related to energy production and managing, environmental protection, and chemical synthesis fields. A global goal, common to all of these fields, is to generate photo-catalytic materials able to use a renewable energy source such as the sun. As most active photocatalysts such as titanium oxides are essentially UV absorbers, they need to be upgraded in order to achieve the fruitful use of the whole solar spectrum, from UV to infrared wavelengths. A lot of different strategies have been pursued to reach this goal. Here, we selected representative examples of the most successful ones. We mainly highlighted doping and composite systems as those with higher potential in this quest. For each of these two approaches, we highlight the different possibilities explored in the literature. For doping of the main photocatalysts, we consider the use of metal and non-metals oriented to modify the band gap energy as well as to create specific localized electronic states. We also described selected cases of using up-conversion doping cations. For composite systems, we described the use of binary and ternary systems. In addition to a main photo-catalyst, these systems contain low band gap, up-conversion or plasmonic semiconductors, plasmonic and non-plasmonic metals and polymers.

“…Semiconductor photocatalysis is an active area of research owing to the increasing concern over environmental cleaning and hydrogen production . Among the semiconductors, anatase titanium dioxide (TiO 2 ) has been widely used because of its wide applications in dye‐sensitized solar cells, photocatalysis, smart surface coatings, lithium‐ion batteries, photo/electrochromics, and sensors .…”

Porous TiO 2 films decorated with Bi 2 O 3 nanoparticles are fabricated via alkalihydrothermal of titanium (Ti) plate by varying the reaction time. The amorphous TiO 2 is transformed into anatase after annealing the films at 500°C in air. The p-type Bi 2 O 3 nanoparticles are successfully assembled on the surface of porous n-type TiO 2 films through the ultrasonic-assisted successive ionic layer adsorption and reaction (SILAR) technique to form Bi 2 O 3 /TiO 2 nanostructure by the two cycles. The obtained Bi 2 O 3 /TiO 2 films are consisted of a well-ordered and uniform porous structure with an average pore diameter of about 100-200 nm containing homogeneously dispersed Bi 2 O 3 nanoparticles of~5 nm diameter. Moreover, the resultant composites present excellent photocatalytic performance toward methyl blue (MB) degradation under UV and visible light irradiation, which could be mainly ascribed to the enhanced light adsorption capacity of unique composite structure and the formation of p-n heterojunctions in the porous Bi 2 O 3 /TiO 2 films. This research is helpful to design and construct the highly efficient heterogeneous semiconductor photocatalysts.
