Large-Scale Synthesis of TiO2 Nanospindle by Liquid Phase Method for Photocatalytic Sewage Treatment

This paper reports a liquid-phase method for the large-scale synthesis of TiO2 nanospindles and evaluates their application in photocatalytic wastewater treatment. By optimizing the synthesis parameters, TiO2 nanospindles with high crystallinity, mesoporous structure, and large specific surface area have been successfully prepared. The synthesized nanospindles are thoroughly characterized. Photocatalytic experiments show that TiO2 nanospindles effectively degrade methylene blue under UV light, achieving near-complete degradation in 15 minutes. Photoluminescence spectroscopy revealed a high recombination rate of photogenerated carriers, indicating the need for further nanostructure optimization to enhance photocatalytic efficiency. This research offers novel perspectives for creating effective materials in wastewater treatment. This study explores the synthesis of TiO2 nanospindles via a liquid-phase method and their application in photocatalysis for wastewater treatment.
