Smog-Eating Buildings?

摘要

For decades, scientists have recognized that, when exposed to sunlight, titanium dioxide acts as a catalyst to break down organic matter, while also creating a superhydrophilic (water-loving) surface. Now, Alcoa Architectural Products has developed a proprietary process that leverages HYDROTECT™ technology from TOTO® to apply a titanium dioxide coating, called EcoClean, to the pre-painted aluminum surface of Reynobond. The result is the world's first coil-coated aluminum architectural panel that cleans itself - and the air around it.
