不久前,化学工程师发现了用二氧化钛来保持建筑物外立面不褪色的方法——当这种材料暴露在阳光和水中时,能分解尘埃和污染物当中的有机物分子,并将分解产物释放到空气中。位于意大利罗马的Misericordia天主教堂、日本东京的Marunouchi大厦等著名建筑已经采用了这种以二氧化钛为主的新型材料,预计 Not long ago, chemical engineers discovered ways to use TiO2 to keep the façade of the building intact - when exposed to sunlight and water, this material can break down organic molecules in the dust and pollutants and release the decomposition products. in the air. Famous materials such as the Misericordia Catholic Church in Rome, Italy and the Marunouchi Building in Tokyo, Japan have already adopted this new type of material based on titanium dioxide.
