“…About 1 h later, almost 90% Cd(II) ions were removed by the adsorbents, and after 3 h, almost all the Cd(II) were removed. The results of the adsorption of Cd(II) are higher than some previously reported [13]. This should not only be ascribed to the ion-exchange ability of the material.…”

“…Sodium titanate is one of the ion exchangers that have been found to have potential application in the treatment of environmental pollutants. In the past decades, many kinds of sodium titanate nanostructures have been fabricated with using various physicochemical methods, including nanotubes, nanowires, nanobelts, and so forth [10][11][12][13][14][15]. However, as far as we know, many of the fabricated nanostructures have the problem of the cost of the method used.…”

Fluffy sodium titanate nanostructures have been fabricated by a simple hydrothermal method with metatitanic acid as precursor. The obtained nanostructures exhibit as the aggregation of nanosheets, and the surface area of the nanostructure is about 110.59 m2/g. Such nanoarchitecture indicates high adsorption capacity to some metal ions, such as Cd2+, and the maximum adsorption capacity has been estimated to be 255.18 mg/g. The possible reasons that are responsible after its high adsorption ability, have been ascribed to the tiny structure, the ion-exchange ability and the large surface area of the sodium titanate nanostructures. And this may greatly enlarge its application potential as an adsorbent.

“…Therefore, in order to enhance the photoelectric property of HTNT materials, numerous efforts have been dedicated on extending their absorption edge of the solar spectrum into visible light region (43% sunlight spectrum) . It is widely accepted that HTNTs are of layered structure with open end morphology , thus they exhibit outstanding structural stability and ion‐exchange properties at room temperature , HTNTs thus can be suitable as a host for intercalation with other ions even oxide particles and small molecules . As demonstrated above, doping by ion‐exchange method is considered to be an effective way to improve the physical and chemical properties of HTNTs, which has been studied widely.…”

Origin of the visible light absorption of Co²⁺ and NH₄⁺ co‐doped hydrogen titanate nanotube thin films

Hydrogen titanate nanotube (HTNT) thin films were synthesized by hydrothermal method and then Co 2þ and NH þ 4 codoped hydrogen titanate nanotube (Co, N-HTNT) thin films were prepared by ion-exchange method. The Co, N-HTNT thin films exhibit strong absorption in the visible light range compared with the HTNT and NH þ 4 doped hydrogen titanate nanotube (N-HTNT) thin films. The first-principles calculations reveal that NH þ 4 doping has no effect on the visible light absorption of HTNTs. The red shift of Co, N-HTNTs is only due to the mixture of the Co 3d and O 2p states in the top of the valence band, which results in the band gap narrowing. Relative to HTNTs and N-HTNTs, both the valence band maximum (VBM) and conduction band minimum (CBM) of Co, N-HTNTs shift to lower potential based on the valence band XPS spectra. Furthermore, the up-shift of the VBM is much larger than that of the conduction band, which can result in band gap reduction explaining the origin of the visible light absorption of Co, N-HTNTs.

Palladium Nanoparticles Supported on Titanate Nanobelts for Solvent‐Free Aerobic Oxidation of Alcohols

The solvent‐free selective oxidation of alcohols by O2 without any additives has been studied using palladium nanoparticles supported on a titanate nanobelt. The catalysts were prepared by polyol reduction and impregnation with different kinds of supports. They were evaluated in oxidation reactions of benzyl alcohol. The calcined titanate nanobelt was found to be the best support for the solvent‐free Pd‐catalyzed oxidation of alcohols and excellent catalytic activity as well as high selectivity to the corresponding benzaldehyde could be obtained. Moreover, palladium nanoparticles immobilized on the calcined titanate nanobelt could completely suppress the formation of toluene and benzoic acid, an effect that might be caused by the enhanced basic nature and morphology of the support. The catalyst was not only active and selective towards carbonyl compounds, but also recyclable under the oxidation conditions. This catalyst was also applicable for the oxidation of other alcohols.
