Synthesis and characterization of anatase tio2 microspheres self-assembled by ultrathin nanosheets
10.3390/ma14112870
The research presents a novel method for synthesizing anatase TiO2 microspheres with a high percentage of (001) facets using potassium fluorotitanate as the sole reagent through a hydrothermal process. The study explores two synthesis methods: the on-site precipitation hydrothermal method and the drop-casting deposition method. The results indicate that the microspheres synthesized at 180–200 °C for 2 hours using the on-site precipitation hydrothermal method exhibit the best crystallinity, shape, and dimensions, with nearly 100% exposed (001) facets. The research highlights the significant effects of temperature and synthesis time on the morphology of the microspheres and anatase nanosheets. The findings suggest that these microspheres have great potential for applications in pollution prevention, environmental protection, and energy fields due to their excellent photocatalytic and photoelectric properties.
