Summary: A hydrogenated black m-TiO2/CeO2 nanocomposite aerogel was prepared and showed enhanced photocatalytic activity in degrading Rhodamine B and water splitting under visible-light irradiation. The photocatalytic enhancement mechanisms included large specific surface area, enhanced conductivity, and the generation of self doped defects in the Z-scheme heterojunction, providing more active sites, extending the absorption range of solar light, and suppressing carrier recombination.

Summary: TiO2 nanostructures are commonly used photocatalysts, but their wide band gap limits their efficiency in utilizing solar energy. Through the synthesis of TiO2/Nb2O5 composites, a unique heterostructure with reduced band gap and improved charge transfer is obtained, resulting in enhanced photocatalytic performance.

Summary: The photocatalytic degradation of carbamazepine, ibuprofen, acetaminophen, and phenol was investigated using different facets of anatase photocatalyst. The {1 0 1} facet of octahedral anatase particles exhibited the highest degradation and mineralization efficiency for all pollutants. A correlation model was developed to predict the degradation rate of pollutants based on the exposed TiO2 crystal facet and the chemical hardness of the pollutant. The study also showed that compounds with higher chemical hardness or a higher HOMO-LUMO energy gap reacted faster with the photocatalyst.

Summary: In this study, mesoporous BiVO4/TiO2 nanocomposites were fabricated to enhance the photocatalytic ability under visible illumination and degrade the antibiotic pollutant model CIP in water. The introduction of BiVO4 effectively improved the separation efficiency of photoinduced carriers and optical absorption. The 3%BiVO4/TiO2 nanocomposite showed the best degradation efficiency and the fastest degradation rate. This study highlights the potential of mesoporous heterojunction BiVO4/TiO2 nanocomposites for photocatalytic performances.

Summary: Due to polluted water remediation, semiconductor nano photocatalysis has been considered as a promising approach to address the issue. However, the slow reaction rates and high electron-hole recombination have hindered their large-scale applications. In this study, heterogeneous nano photocatalysts, such as sol-gel-based mesoporous titania nanoparticles (TNPs) and silica-titania nanocomposite (STNC) supported with CdTe (CdTe/STNC), were synthesized for photocatalytic applications. The CdTe/STNC catalyst exhibited a large surface area and pore size distribution, and demonstrated high photocatalytic activity with methylene blue degradation of 95% after 180 min of ultraviolet radiation.

Summary: Novel phosphorus and sulfur co-doped graphitic carbon nitride incorporated in 2D TiO2 structure were successfully fabricated and applied for solar-driven degradation of pharmaceutical pollutants. The hybrid photocatalysts were characterized and showed improved photocatalytic activity towards the degradation of carbamazepine and acetaminophen. The results suggested that the (P, S)-doped g-C3N4/2D TiO2 heterostructure is a Z-scheme heterojunction, effectively separating photogenerated charge carriers.

Summary: The one-step aerosol-assisted self-assembly (AASA) process was used to synthesize CuTMS materials, which played a crucial role in catalytic CO oxidation reaction. The dispersion of copper was significantly enhanced, leading to the formation of Cu-O-Ti bonds in the lattice, altering the electron densities of Ti and O.
