Heterojunction photocatalytic materials show excellent performance in degrading toxic pollutants. This study investigates the influence of calcination temperature on performances floral Bi2O3/TiO2 composite photocatalyst crystal, which was prepared with glycerol, bismuth nitrate, and titanium tetrachloride as major raw via solvothermal method. XRD, SEM/TEM, BET, Uv-vis, XPS were employed to ana...

We have developed a simulation tool to model self-limited processes such as atomic layer deposition (ALD) and etching inside reactors of arbitrary geometry well the output in situ quartz crystal microbalance mass spectrometry. applied this two standard types cross-flow reactors: cylindrical tube reactor 300 mm wafer reactor, explored both ideal nonideal kinetics. The results are agreement with ...

A new non-precious metal oxygen reduction catalyst was developed via heat treatment of in situ polymerized polyaniline onto TiO(2) particles in the presence of Fe species. The TiO(2) provides for improved performance relative to a carbon black-based catalyst and, at a high catalyst loading, allows for reducing the performance gap between non-precious-metal catalyst and Pt/C to ca. 20 mV in RDE ...

A novel intramolecular Prins type cyclisation of cyclopropylvinylic aldehydes promoted by TiCl(4) under mild reaction conditions to form cis-cyclic products in high yields has been accomplished.

In this work, thermal based gas-phase etching of titanium nitride (TiN) is demonstrated using thionyl chloride (SOCl2) as a novel etchant. A single etchant utilised in pulsed fashion to etch TiN. This type technique may also be considered chemical or dry etching. The removed TiN amount was measured by various techniques like spectroscopic ellipsometry (SE), weighing balance and some cases X-ray...

The replacement of oxide semiconducting TiO₂ nano particles with one dimensional TiO₂ nanotubes (TNTs) has been used for improving the electron transport in the dye-sensitized solar cells (DSSCs). Although use of one dimensional structure provides the enhanced photoelectrical performance, it tends to reduce the adsorption of dye on the TiO₂ surface due to decrease of surface area. To overcome t...
