“…The as-prepared LPD TiO 2 films exhibit high photoelectrochemical activity and can be applied to the degradation of organic pollutants [29,30]. Meanwhile, LPD technique also provides a ready process for forming TiO 2 -based hybrid thin films by simply doping organic or biological materials into the deposition solution [31][32][33][34][35]. Recently, we prepared SDS/TiO 2 hybrid film and observed that SDS could improve the electrocatalysis of Hb towards H 2 O 2 after Hb was adsorbed on the hybrid film [36], although we did not observe the direct electrochemistry of adsorbed protein.…”

“…LPD-prepared thin film nanostructures can be used to improve the performance of photo-electrochemical cells. Mesoporous TiO 2 thin films can also be treated with organic dopant such as DNA and methylene blue to TiO 2 film [11,12]. LPD was augmented with the addition surfactant into solution as described in several reports [13][14][15].…”

TiO 2 nanostructures have been treated using different kind of surfactant to modify its optical absorption and morphology. TiO 2 nanostructures were prepared via simple method on indium tin oxide (ITO) surface, namely, liquidphase deposition technique (LPD) at 50°C. The TiO 2 nanostructures film with a thickness of about 236 nm was annealed at 400°C for 1 h in the air to enhance the interconnectivity of the particles. The dense and compact TiO 2 nanoparticle with different shape, particle size and surface morphology was used as a photovoltaic material in a photoelectrochemical cell of ITO/TiO 2 /electrolyte/platinum. TiO 2 nanostructure films were treated with three different kinds of surfactants: cetyltrimethylammonium bromide (CTAB), hexamethylenetetramine (HMT) and polyvinylpyrrolidone (PVP). It was found that the film treated with HMT performed best, with a J sc of 57.5 μA/cm 2 . In conclusion, optical absorption, band gap and grain size of TiO 2 nanostructure influenced the performance of the cell.

“…The behavior of amines as adsorbates on TiO 2 nanosystems has recently attracted considerable interest, since they are widely used as nitrogen source in the synthesis of N-doped TiO 2 nanocrystals, acting either as precursors or as post-synthetic modifying agents [17][18][19][20], and also because polymers containing amino groups are often employed together with TiO 2 nanoparticles in nanocomposite materials [21][22][23][24]. Moreover, new promising solid-state sensitized solar cells rely on hybrid organic/ inorganic perovskite materials that are composed of methylammonium, lead cations and halide anions [25][26][27].…”

Titanium dioxide (TiO2) nanorods are widely employed in many energy-related applications thanks to their peculiar electronic and physicochemical properties. Here we report a periodic DFT and DFT-D study of the three most exposed surfaces of stoichiometric anatase TiO2 nanorods, i.e., (100), (001) and (101). On these surfaces, we investigated the adsorption of a tertiary amine (trimethylamine, TMA): Energetic, structural and electronic features have been characterized, paying particular attention on the effects of dispersion forces on the adsorption process. We found evidence of the formation of a coordinative bond between the molecules and the titanium site of adsorption. As expected, the inclusion of dispersion correction strongly enhances the adsorption process. Moreover, in some cases TMA adsorption introduces new electronic states at the edge of the valence band. Overall, our results provide new insights on the interactions between TiO2 nanorods and nitrogen compounds, which have many scientific and technological implications
