Summary: Single crystalline anatase TiO2 microspheres with {001}/{101} facets were synthesized via a facile one-pot hydrothermal method using NaF as a morphology controlling agent. The effects of NaF amount on morphology and photocatalytic activity were systematically investigated. Results showed that microspheres with improved morphology were obtained at a NaF concentration of 0.1 mol/L. Furthermore, the crystal structure and morphology were found to play significant roles in the photocatalytic activity, with TiO2 microspheres achieving a degradation efficiency of 76.4% for Tetracycline hydrochloride within 2 hours. A growth mechanism involving F ion modified Ostwald ripening and oriented attachment was proposed based on the investigation of the growth process.

Summary: In this study, a multi-layer core-shell structure of SiO2@Ag@SiO2@TiO2 was synthesized as a photocatalyst for the degradation of dye pollutants. The optimal coating effect was achieved by using a mass ratio of AgNO3, TEOS, and TBOT to SiO2 at 5:2.4:6:1, and the core-shell structure showed the best photocatalytic activity. The degradation efficiency of the SiO2@Ag@SiO2@TiO2 photocatalyst was close to 93% after 45 minutes of simulated visible light irradiation, and it maintained a degradation efficiency of 90% after 4 cycles of recycling tests. This research has significant importance for water pollution control.

Summary: The wollastonite-nanoTiO(2) composite, WOT-PC, exhibits promising photocatalytic performance and recycling ability due to the stable chemical binding of Ca-O-Ti and Si-O-Ti, as well as the promotion of electron-hole separation efficiency by Ca-O-Ti. UPS analysis suggests that electron movement to the surface of TiO2 is facilitated after wollastonite supports nanoTiO(2), leading to enhanced photocatalytic performance. The superhydrophilicity and self-cleaning ability of WOT-PC make it a potential candidate for outdoor wall coatings.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
