Templated synthesis of ordered porous TiO2 films and their application in dye-sensitized solar cell

Structure–activity relationship of nanosized porous PEG-modified TiO2 powders in degradation of organic pollutants

“…Much effort has been exerted to achieve highly crystallized materials with retained surface area and porosity. One of the attractive method to retain the catalyst porous structure after calcination is to use organic templates during catalyst synthesis, such as polyethylene glycol (PEG) [21][22][23][24][25], Pluronics triblock copolymer P123 [26,27], polystyrene [28] or biocomposite gel [29]. Decomposition of polymers during thermal treatment can lead to generation of porous structure, thus improving the textural properties of the catalysts.…”

Hybrid Synergic Methodology to Prepare ALD Honey‐Comb Anatase Films

“…The possibility of obtaining ordered and long‐ranged periodic metal oxide surfaces of micrometric and sub‐micrometric dimensions is interesting for the exploitation of their high aspect ratio in the field of catalysis, photovoltaic or sensors . Although structuring micro and nanomaterials is possible with conventional templating and lithographic techniques, alternative approaches exploiting the self‐assembly of a wide range of polymeric materials as templates may also be considered, such as the breath figures (BFs) method or colloidal particle arrays . They are simple, fast and do not require any relevant machinery.…”

“…The choice to deposit titania (TiO 2 ) is stimulated by its unique features, such as a large direct band gap (3.2 eV), excellent chemical and thermal stability, electrical and optical properties. Moreover, ordered TiO 2 films have received much attention due to their potential application in various areas such as photoelectrochemical solar cells, electrocatalysts, sensors, high‐performance photocatalysts and so on . Furthermore, the ALD methodology proposed here can be potentially applied to other metal oxides, such as ZnO, Al 2 O 3 , SiO 2 , etc …”

Surface Texturing of TiO2 Film by Mist Deposition of TiO2 Nanoparticles

“…The main applications of TiO 2 films are in solar cells [1], gas sensors [2], optical coatings [3], photo-catalytic systems [4], and other devices. For many applications, porous TiO 2 films have attracted considerable attention because of large surface areas [5], highly ordered porous structures [6], and well-defined pore sizes and porosity [7]. There are various preparation methods of porous TiO 2 films such as sol-gel method [8], templating assembly method [9], reverse micelle [10], spray-pyrolysis method [11], aerosol deposition [12] and cathodic electrodeposition [13].…”
