Titanium dioxide (TiO) has been widely used to solve energy and environmental pollution problems due to its excellent properties. In this study, the precursor (HTiOF) with a spherical structure composed of hexagonal prisms was prepared via a simple solvothermal method using tetrabutyl titanate, hydrofluoric acid, glacial acetic acid and isopropanol as raw materials. Then, the calcination time and temperature of the precursor were controlled to prepare anatase TiO with different morphologies, and the photocatalytic performance of the prepared catalysts was studied. When the precursor was calcined at 600 °C for 7 h, the prepared TiO had a unique hexagonal framework structure and exhibited excellent photocatalytic performance. The degradation rate of the RhB solution was 98.58% at 40 min and the rate of hydrogen evolution was 2508.12 μmol g h.
二氧化钛（TiO₂）因其优异的性能而被广泛用于解决能源和环境污染问题。在本研究中，以钛酸四丁酯、氢氟酸、冰醋酸和异丙醇为原料，通过简单的溶剂热法制备了由六棱柱组成的具有球形结构的前驱体（HTiOF₄）。然后，控制前驱体的煅烧时间和温度，制备了不同形貌的锐钛矿型TiO₂，并研究了所制备催化剂的光催化性能。当前驱体在600℃下煅烧7小时时，所制备的TiO₂具有独特的六方框架结构，并表现出优异的光催化性能。在40分钟时，RhB溶液的降解率为98.58%，析氢速率为2508.12μmol g⁻¹ h⁻¹。
