“…The researchers have made extensive studies on the electrorheological performance of titanium dioxide. [ 5,17,18 ] However, in the actual test process, we found that the ER performance of titanium oxide is not ideal and its density is high comparing with silicone oil. Therefore, many researchers began to prepare titanium oxide with different morphologies to improve its ER performance.…”

“…In the previous research, we found that the leakage current density of the hollow TiO 2 template is too large to conduct a normal test, [ 18 ] so a calcination process was added before the test to remove the surface hydroxyl groups and water molecules adsorbed by titanium oxide. Silicon oxide is not only a good insulator but also a perfect coating material.…”

Although titanium oxide has a high dielectric constant, ordinary titanium oxides are not a good electrorheological (ER) fluid material. Herein, hollow peanut-like titanium oxide spheres are synthesized by hydrothermal method, and then coated with silicon oxide to form core-shell hollow TiO 2 @SiO 2 spheres. The structure is characterized by different methods, and the TiO 2 @SiO 2 composite particles are dispersed in silicone oil to prepare an ER suspension. The ER effect of 10% TiO 2 @SiO 2 -based ER fluid under different electric field strengths is tested, and its performance is analyzed. The results show that the coated particles significantly enhance the current meter performance. The shear stress value exceeds 200 Pa at an electric field strength of 3.0 kV mm À1 . The shear stress, shear viscosity, switching effect, and dielectric behavior of the base ER fluid are studied. And, the cause of this strong ER effect is studied. In the end, it is found that TiO 2 @SiO 2 peanut-shaped composite core-shell particles have a good ER effect and which is a kind of ER candidate material with simple preparation and development prospect.

The morphology of TiO2 nanoparticles has great influence on their physical/chemical properties. Controlled synthesis of TiO2 with adjustable morphologies is of utmost importance for their target applications. Herein, a series of TiO2 with continually adjustable shape, size and crystal structures were synthesized via the hydrolysis of titanium isopropoxide, followed by the self-assembly using P123 as structure-directing agent and ethylene glycol as co-surfactant under different solvothermal conditions. The effect of the diverse experimental conditions on the TiO2 nanostructures was systematically investigated. Particularly, an optimum TiO2 nanosheet was achieved and the formation of liquid crystal phase was observed. This work provides useful enlightenment for the fabrication of TiO2 nanostructures, which can be potentially employed in diverse fields, such as dielectric materials and photocatalysts.

“…Usually, semiconductor materials with photocatalytic properties, such as TiO 2 ,C e O 2 ,W O 3 , ZnO, Fe 2 O 3 , and so on can be used to treat wastewater. Among them, nano TiO 2 material is prominent for its high stability and activity, non-toxic, low cost and harmless nature [4][5][6][7][8][9]. Compared with ordinary powder materials, tubular TiO 2 is prominent due to its fast electron transfer and high catalytic activity [10,11].…”

Compared with common TiO 2 powder, TiO 2 nanotubes can exhibit better catalytic performance for their high specific surface area. By using hydrogen TiO 2 nanotubes synthesised via the hydrothermal process as carriers, carbon and platinum co-modified TiO 2 nanotubes (C-Pt/ TiO 2 NTs) were prepared via impregnation-photoreduction method in this study. X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, and infrared spectrum were used to characterise the structure and composition of the prepared samples. Their catalytic activities for degrading methyl orange under ultraviolet (UV) illumination and simulated sunlight were evaluated. The influences and mechanism of dopants and their contents on the catalysts' activity were investigated. Obtained results indicated that the modification can improve the photocatalytic activity of TiO 2 nanotubes under both UV light and simulated sunlight. Among them, C-Pt/ TiO 2 NTs with 0.5 wt% Pt exhibited the best performance.
