【摘要】 在介绍纳米TiO₂的结构和性能的基础上,阐述了气相法和液相法2种制备纳米TiO₂的重要方法,叙述了纳米TiO₂材料在化妆品、环境保护、医疗卫生、建筑材料和新能源等光催化技术领域的应用研究进展。纳米级TiO₂因光化学稳定性较高、比表面积较大,较强的氧化还原性及成本低、无毒等优势而成为半导体光催化剂中最受瞩目的光催化材料之一,但基于技术、成本、性能和产品安全性等方面的实际开发和应用还需要进一步发展和完善。更多还原

【Abstract】 As a new type of nano-functional powder material, nano-TiO₂ has important applications in high-tech fields such as environment and energy due to its low cost, good stability, safety, non-toxicity, and high photocatalytic activity. On the basis of introducing the structure and properties of nano-TiO₂, the important methods for preparing nano-TiO₂, such as the gas phase method and the liquid phase method, are described. The application and research progress of nano-TiO₂ in the fields of cosmetics, environmental protection,medical and health, building materials and new energy were reviewed.更多还原
