“…On the other hand, Yb has an unfilled 4f orbital and an empty 5d orbital, which can receive and transmit photogenerated electrons, making its conduction band and valence band become traps for capturing the photogenerated electrons and holes, respectively, thus promoting the effective separation of photogenerated carriers. 38 Therefore, the Yb-Bi 2 S 3 /ITO electrode was chosen as the photoanode to construct a NIR PEC sensor for ATP detection.…”

Novel dahlia-like TiO 2 structures were successfully synthesized by an ethylenediamine (EDA)-assisted hydrothermal method. The EDA served as ligand and facilitated the growth of dahlia-like TiO 2 structures. Particularly, the dahlia-like TiO 2 structures were built by twodimensional (2D) thin nanosheets, which interconnected with each other. In addition, the dahlia-like TiO 2 structures own relatively large specific surface areas of 158.85 m 2 /g. Furthermore, the dahlia-like TiO 2 structures exhibit higher photocatalytic activity than that of commercial P25 for degradation of Rhodamine under UV light irradiation. The enhanced photocatalytic activity is due to the synergetic effect of the architecture and high BET surface area of the photocatalyst.

a This study differs from previous studies of TiO 2 /SiO 2 in that 0.5-10 mm microsized TiO 2 -rutile based catalysts (TR catalysts) with varying proportions of titanium and silicon were synthesized using a onestep modified hydrothermal method. At Ti/Si ¼ 1/9, a two-dimensional channel-structured catalyst with a morphology resembling that of SBA-15 was obtained. In contrast, at Ti/Si ¼ 3/7 or 5/5, a threedimensional porous structure was formed, and Ti-O-Si-C bonds appeared. The structure of the TR catalyst transformed due to the decrease in C-Si bond content and the increase in C-C bond content with increasing Ti/Si ratio. The results indicated that the rutile phase was the main crystal phase of the TR catalyst. The small crystal size and large rutile phase content of the mesoporous TR catalyst contributed to the low band gap energy below 3.0 eV. Under 2 Â 10 W lamp irradiation with either UVA or visible light, the three TR catalysts showed better formaldehyde (HCHO) removal efficiency than P25. Overall, the Pt/TR catalyst is a potential material for pollutant removal and can be easily separated from the pollutant removal system since the catalysts are microsized.
