A nitrogen-doped TiO2@SiO2 core/shell nano-photocatalyst (N-TiO2@SiO2) was used as an additive in photocatalytic paint and applied for the degradation of gaseous acetaldehyde under light-emitting diode (LED) visible light irradiation. N-TiO2 synthesised via solvothermal method then encapsulated by SiO2 sol-gel method. The incorporation N atom into TiO2 structure observed X-ray photoelectron spe...

This is the first time we report that simply air plasma treatment can also enhances the optical absorbance and absorption region of titanium oxide (TiO2) films, while keeping them transparent. TiO2 thin films having moderate doping of Fe and Co exhibit significant enhancement in the aforementioned optical properties upon air plasma treatment. The moderate doping could facilitate the formation o...

Doping of titania nanotubes is one of the efficient way to obtain improved physical and chemical properties. Through electrochemical anodization and annealing treatment, Ni-doped TiO2 nanotube arrays were fabricated and their hydrogen sensing performance was investigated. The nanotube sensor demonstrated a good sensitivity for wide-range detection of both dilute and high-concentration hydrogen ...

This study explores a facile method to prepare an efficient and durable support for Pt catalyst of polymer electrolyte membrane fuel cell (PEMFC). As a candidate, Nb-doped TiO2 (Nb-TiO2) nanofibers are simply fabricated using an electrospinning technique, followed by a heat treatment. Doping Nb into the TiO2 nanofibers leads to a drastic increase in electrical conductivity with doping level of ...

Objective(s): Adsorption of IMMUCILLIN-A (BCX4430) molecule on the pristine and N-doped TiO2 anatase nanoparticles were studied using the density functional theory (DFT) calculations. The adsorption energy analysis indicated that TiO2+IMMUCILLIN-A complexes including OC-substituted TiO2 have higher adsorption energy than the complexes with OT substituted TiO2, thus providing mo...

The over expression of thioredoxin domain-containing protein 5 (TXNDC5) can promote the growth of castration-resistant prostate cancer (CRPC). A novel highly sensitive photoelectrochemical (PEC) aptsensor was developed for the detection of TXNDC5 by using the nanohybrids (TiO2 NRs/NCQDs) of nitrogen-doped carbon quantum dots (NCQDs) and TiO2 nanorods as the photo-to-electron conversion medium. ...

in the current study, pure tio2 and cr-doped tio2 (cr@tio2) nanoparticles were synthesized via sol-gel method and the resulting materials were applied to prepare the porous tio2 electrodes for dye-sensitized solar cells (dsscs). it is hypothesized that the advantages of the doping of the metal ions into tio2 lattice are the temporary rapping of the photogenerated electron-hole (charge carriers)...

It is attractive to manipulate the volatile and non-volatile resistive switching behaviors of memristors create genuine neuromorphic systems such as artificial neural networks (ANNs) spiking (SNNs). To investigate above behaviors, nitrogen has been introduced into TiO2 nanorod arrays (TiO2 NRAs) by hydrothermal processing. X-ray photoelectron spectroscopy (XPS) analysis shows that both lattice ...
