二氧化钛纳米材料在二氧化碳转化、水处理、空气质量控制等光催化环境领域具有广阔的应用前景和优异的性能。在这些应用中，颗粒大小、晶体结构和相、孔隙率和表面积会极大地影响tio2的活性。纳米球、纳米线、纳米管、纳米棒和纳米花等具有特殊结构和形态的tio2纳米材料由于其所需的特性而被合成。重点介绍了tio2的不同形态及其合成的影响因素，综述了溶胶-凝胶法、溶剂热法、反胶束法等14种制备tio2的方法。介绍了tio2的形成机理、制备方法的优缺点以及光催化环境应用实例。
TiO2nanomaterial is promising with its high potential and outstanding performance in photocatalytic environmental applications, such as CO2conversion, water treatment, and air quality control. For many of these applications, the particle size, crystal structure and phase, porosity, and surface area influence the activity of TiO2dramatically. TiO2nanomaterials with special structures and morphologies, such as nanospheres, nanowires, nanotubes, nanorods, and nanoflowers are thus synthesized due to their desired characteristics. With an emphasis on the different morphologies of TiO2and the influence factors in the synthesis, this review summarizes fourteen TiO2preparation methods, such as the sol–gel method, solvothermal method, and reverse micelle method. The TiO2formation mechanisms, the advantages and disadvantages of the preparation methods, and the photocatalytic environmental application examples are proposed as well.
