In the planar perovskite solar cells (PSCs), the electron transport layer (ETL) plays a critical role in electron extraction and transport. Widely utilized TiO2 ETLs suffer from the low conductivity and high surface defect density. To address these problems, for the first time, two types of ETLs based on TiO2 phase junction are designed and fabricated distributed in the opposite space, namely a...

The use of chlorine bleaching in study and pulp industry has resulted in chlorinated phenol contaminated wastewater from that industry. A new wastewater treatment process, sonophotodegradation of 2,4,6-trichlorophenol (TCP) in a heterogeneous aqueous system was investigated and reported in this study. TCP was degraded with ultrasonic or ultraviolet irradiation or a combination of both, in the p...

catalytic and photocatalytic reactions of (2-chloroethyl) phenyl sulfide (2-ceps), a mimic of bis (2-chloroethyl)  sulfide (i.e. sulfur mustard) were studied on the surfaces of titanium oxide. tio2 nanoparticles (anatase, rutile and mixture of 80% anatase/20% rutile) along with bulk tio2 were tested as reactive sorbents for reaction of 2-ceps at room temperature (25±0.5°c). reactions were monit...

Without any...

To magnify anatase/rutile phase junction effects through appropriate Au decorations, a facile solution-based approach was developed to synthesize Au/TiO2 nanoforests with controlled Au locations. The nanoforests cons®isted of anatase nanowires surrounded by radially grown rutile branches, on which Au nanoparticles were deposited with preferred locations controlled by simply altering the order o...

The nuclear quadrupole interaction of the first excited I=1 state of Sc in the anatase and rutile modifications of bulk TiO2 was determined by time-differential perturbed-angular correlation of rays. New LaBr3 Ce scintillators with excellent energy resolution allowed us to separate the 68 and 78 keV lines of the cascade. For anatase, an almost axially symmetric electric field gradient EFG with ...

Titanium dioxide nanoparticles (TiO2NPs) induce lung inflammation in experimental animals. In this study, we conducted a comprehensive toxicogenomic analysis of lung responses in mice exposed to six individual TiO2NPs exhibiting different sizes (8, 20 and 300nm), crystalline structure (anatase, rutile or anatase/rutile) and surface modifications (hydrophobic or hydrophilic) to investigate wheth...

Textural evolution (porosity reduction, pore and crystallite growth) in titania-alumina composite membranes has been studied using thermal analysis, X-ray diffraction, field emission scanning electron microscopy and N, physisorption techniques. The presence of alumina in the membranes improved the thermal stability of the porous texture by retarding the anatase-to-rutile phase transformation a...

Anatase, one of the polymorphs titanium dioxide (TiO2), has become most widely used semiconductor for photocatalytic materials due to its chemical and physical properties. However, researchers have been studying use alternative (e.g., ZnO, N-doped, C-doped TiO2) improve activity cementitious materials. In this paper, we propose a modification lightweight concrete by introducing mixed phases dio...
