Liquid phase deposition of hemoglobin/SDS/TiO2 hybrid film preserving photoelectrochemical activity

Morphology, structure, optical property and photoelectrochemical property of TiO 2 nanoflower films synthesised via liquid phase deposition technique

“…4 shows the UV-vis absorption spectrum of the sample deposited for 4 h. The curve indicates the appearance of the absorption spectrum in the wavelength ranges from visible light to near infrared. It is observed from the Figure that the sample shows strong absorption at the wavelength less than 370 nm, similar to the TiO 2 sample that absorbed UV light at the wavelength less than 350 nm reported by Wang et al [17]. The spectrum of the sample deposited for 4 h displays a prominent absorption near the blue region (350-400 nm).…”

Ionic Equilibria for Synthesis of TiO2 Thin Films by the Liquid-Phase Deposition

“…Hence, a detailed understanding of the equilibria of the various chemical species in the LPD reaction solution is indispensable to achieving high yields and optimizing the physical properties of the thin films. The LPD method has been widely applied for the fabrication of different kinds of films, such as titanium oxide, ,− vanadium oxide, , iron oxy-hydroxide, ,, layered double hydroxide, − and complex three-dimensional structured metal oxide films. − Furthermore, thin films synthesized by the LPD reaction can be applied in catalysts, − solar cells, − secondary batteries, − ,, and anticorrosion coatings. , In the present study, to elucidate the deposition mechanism, the LPD reaction was investigated by various spectrophotometric techniques including ultraviolet–visible, IR, and Raman spectroscopy. , However, there is much room for further intrinsic investigation with respect to the solution equilibria in the LPD reaction solution, and control of the LPD reaction conditions is still limited. ,− …”

High-efficiency solid-phase microextraction performance of polypyrrole enhanced titania nanoparticles for sensitive determination of polar chlorophenols and triclosan in environmental water samples

“…It had been reported in the literature that the introduction of a large counter anion such as anionic surfactants during the preparation of the PPy, leads to improved properties of the polymers. 40,41 …”

“…Thereaer the prepared ber was washed with acetone and ultrapure water to remove pyrrole monomers in the PPy@TiO 2 NPs coating, and dried in vacuum for 3 h at 90 C. It had been reported in the literature that the introduction of a large counter anion such as anionic surfactants during the preparation of the PPy, leads to improved properties of the polymers. 40,41 The added SDS will link with TiO 2 via sulfonate-like ester bonds, improving the lipophilicity of the surface of TiO 2 NPs, and making pyrrole easy to polymerize on its surface. The generated PPy strengthens the bond to inorganic materials, making the polymer difficult to remove.…”
