Summary: TiO2 nanomaterials were synthesized through a sol-gel method using titanium butoxide as a precursor, Pluronic F127 as a template, toluene as a swelling agent, and acidic water or ethanol as reaction solvents. The synthesis medium influenced the phase composition of the solids, with ethanol promoting dispersed anatase particles and water leading to a rutile phase. The photocatalytic activity of the samples was tested by the photodegradation of Rhodamine B.

Summary: In this study, silver nanoparticles of two different sizes were prepared and compounded with semiconductor materials, demonstrating the photocatalytic enhancement of the system. It was found that the hydrogen yield was almost unaffected by the silver core diameter and the hydrogen production rate was essentially the same. Additionally, the rate of hydrogen precipitation in air for 9 months was significantly higher than previous studies, providing a new idea for the study of oxidation resistance and stability of photocatalysts.

Summary: Hierarchical aggregates of anatase TiO2 nanoribbons/nanosheets (TiO2-NR) and anatase TiO2 nanoparticles (TiO2-NP) were synthesized using a solvothermal reaction. TiO2-NR exhibited a three-dimensional hierarchical structure, while TiO2-NP had a nanoparticulate structure. Compared to commercial TiO2 (P25), both TiO2-NR and TiO2-NP showed higher photocatalytic and photocurrent performance. The solvothermal synthesis method used in this study offers potential for various energy harvesting applications.

Summary: In this study, TiO2/CdS nanocomposites with different exposed facets were synthesized and characterized. Among them, FMA-TiO2/CdS exhibited the highest photocatalytic activity with a degradation efficiency of 88.4%, attributed to its largest surface energy, co-exposed {101}/{010} facets, lowest photoluminescence intensity, lower charge-transfer resistance, and higher charge-transfer efficiency.

Summary: This study aims to synthesize various TiO2 nanocrystals, including nanosheets, nanorods, and nanoparticles, using a rapid hydrothermal method. The synthesized TiO2 nanocrystals exhibit high purity and exposed high-energy facets, resulting in high reactivity and large surface area. The {001} facets dominate in the nanosheets and nanorods, accounting for approximately 80% and 85% of the outer surface area, respectively.

Summary: In this study, a 3D hierarchical flower-like rutile TiO2 microsphere with well-aligned 1D nanorods was successfully synthesized using the solvothermal method. The synthesized TiO2 microspheres showed a average crystallite size of 6.9-8.4 nm and were composed of radially grown nanorods. Analysis confirmed the presence of titanium and oxygen peaks without impurity peaks. The volume ratio of water and toluene significantly affected the chemical properties of the synthesized TiO2 materials. The Ti(1:1) hierarchical 3D TiO2 microspheres exhibited a small crystallite size, a lower bandgap, a large BET surface area, and a high pore volume, indicating enhanced photocatalytic activity.

Summary: In this study, Ti3C2-TiO2 composite materials with good control of size and morphology were successfully prepared via a simple method, leading to significantly enhanced photocatalytic hydrogen evolution activity. The improved H-2 production rate of the Ti3C2-TiO2 composites can be attributed to the facet control and extended light absorption effect of TiO2 nanoparticles.
