Abstract Over the past decades, the accumulation of organic pollutants in surface water, groundwater, and even drinking water have raised as a serious issue. A photocatalytic process using a semiconductor like TiO2 is one solution for the degradation of organic pollutants in water, however, the low efficiency of the photocatalytic reaction is still a problem. In recent years, increasing the efficiency of semiconductors by controlling the structure and morphology has been in the spotlight, and hollow structures have gathered specific attention thanks to their unique structure. In this study, hollow TiO2 particles with different shell thicknesses are synthesized and the effect of particle size and shell thickness on photocatalytic activity of TiO2 has been investigated.

不同壳厚TiO2中空纳米粒子的合成及结构对光催化活性的影响

摘要 在过去的几十年中，地表水、地下水甚至饮用水中有机污染物的积累已成为一个严重的问题。使用二氧化钛等半导体的光催化过程是降解水中有机污染物的一种解决方案，但光催化反应效率低仍然是一个问题。近年来，通过控制结构和形貌来提高半导体效率一直是人们关注的焦点，而空心结构由于其独特的结构而受到特别关注。在这项研究中，合成了具有不同壳厚度的中空 TiO2 颗粒，并研究了粒径和壳厚度对 TiO2 光催化活性的影响。
