Toyota’s Breakthrough M2LFh Technology Will Remove 95% of Ozone from the Air
Ozone is a ground-level air pollutant that plagues cities, especially those overrun by cars. But now Toyota’s Central Research and Development labs have announced the development of a material that removes 95% of unreacted ozone from the air when used in an ozone filter. The material is called mesoporous two-line ferrihydrite or M2LFh (say that ten times fast) and is porous, which gives it a large inner surface area with numerous iron sites near the surface for absorbing ozone. What does all this mean? The car you drive around could actually clean the air instead of adding to air pollution.
According to the researchers’ report on their research into M2LFh, “…Among a wide range of materials tested at room temperature, we found M2LFh to be the most efficient candidate for O3 removal; it showed about 95 percent O3 removal with high reproducibility.” The graph above was produced by Toyota, so while it is impressive, we can’t be sure it doesn’t exclude some other emerging technology with similar promise. We will keep an ear to the ground for other related research out there.
