Abstract：Started from the preparation of titania microspheres, the method principle, raw materials of various methods and the structural performance and appearance characteristic of the obtained microspheres were reviewed. The advantages and the drawbacks of such methods were summarized. This review detailed the latest advances in application of this material in environmental pollution, dye-sensitized solar cells and electronic ink with varying, structure and performance of titania microspheres and extensively discusses the influence of titania microspheres structure on its properties and applications.Furthermore, based on the disadvantage existing in preparations and applications, the three main directions in future research of TiO₂ microspheres were pointed out: to design specific structure, to dopant to expand the reactivity wavelength range, and to explore the simple and economic preparation.
