A novel preparation of highly active iron-doped titania photocatalysts with a p–n junction semiconductor structure

Structural Aspects of Anatase to Rutile Phase Transition in Titanium Dioxide Powders Elucidated by the Rietveld Method

“…Innovative semiconductor arrangements like p-n junction, titanium dioxide glass-ceramic, ion-sodium battery based on anatase titanium dioxide ceramic matrix are also investigated in order to provide new applications concerning novel structures and morphologies degrees, making the titanium dioxide much more investigated [10][11][12].…”

“…In addition, the reported enhancement in photocatalytic performance for homovalent doping cannot be related exclusively to the decrease in oxygen vacancies [28]. The effect in crystal surface can play an important role in order to reduce the recombination of electron-hole pair, and the anatase phase surface presenting oxygen and cations outer of the plane seems to be crucial to avoid that auto-neutralizing phenomenon [10,31].…”

Development of photocatalytic coupled zinc–iron oxide nanoparticles via solution combustion for bisphenol-A removal

“…Photocatalysts such as titanium dioxide (TiO 2 ) and zinc oxide (ZnO) are semiconductors that able to absorb the energy from light and subsequently excite their electrons from the valence band to conduction band (Liu et al, 2010;Karunakaran et al, 2011;Meshram et al, 2011;Bai et al, 2012). These generated holes and electrons are capable to create radicals to initiate a series of redox reaction.…”

“…However, in such condition, high energy light source, such as ultraviolet ray, is required for the photo-excitation and initiation of the photocatalytic reaction. Therefore, another approach that involves the creation of pen junction between two different types of photocatalyst has been established to minimize the recombination effect Shifu et al, 2009;Liu et al, 2010). The pen junction formed through the coupling process act as pathway for the continuous diffusion of electronehole pair to generate a distinct charge of p-type and n-type photocatalyst.…”

Iron doped thin TiO2 films synthesized with the RF PECVD method

“…Due to its simplicity, iron doped TiO 2 coatings are usually manufactured with the sol-gel technique [16,17]. In the present work, a radio frequency plasma enhanced chemical vapor deposition (RF PECVD) method has been applied for the same purpose.…”
