Maybe. A mineral made from the oxide family has been found to cut diesel-engine pollution by as much as 45 percent and may be able to replace the use of platinum as a pollution-reducing agent, the website Environmental Protection reported, citing the periodical Science.
A man-made version of mullite – the oxide – is not only more effective at cutting diesel pollution but will likely be cheaper to produce than platinum, which is considered a precious metal. The discovery was made by a company led by Dr. Kyeongjae Cho, a professor at the University of Texas, Dallas, and may lead to commercialization of the product.
The issue of diesel pollution, especially from trucks, has gained importance as more people become aware of climate change and greenhouse-gas emissions. Diesel pollution hit the headlines in June when the World Health Organization officially linked diesel exhaust to lung and bladder cancers after studying reports by the International Agency for Research on Cancer (IARC).
