摘要

纳米二氧化钛（n-TiO2）由于其独特的光催化和疏水性能，可用于制备自洁水泥基智能建筑材料。n-TiO2
通过其光催化作用降解有机和无机污染物，并将其转化为无毒的副产品，即改善空气质量。本文综述了n-TiO2的合
成方法、n-TiO2在水泥基材料上的负载方法、光催化性能、自清洁机理以及n-TiO2在水泥基材料中的应用等方面。
此外，n-TiO2可用作路面砌块、斑马线处的砂浆/混凝土、道路分隔物和衬砌以及高层建筑中的涂料或外加剂。此
外，在水泥基材料中使用n-TiO2的影响和经济方面表明，与传统建筑材料相比，n-TiO2将材料成本增加了约27%
（101至128.1美元）。此外，已经建议使用低成本的碳化材料如生物炭作为n-TiO2的载体，以降低成本并提高光催化
混凝土的修复效率。
