In densely populated urban areas, such as Los Angeles, smog is a well-known problem.
Air pollution hangs over the city like a dirty cover, and the urban heat island effect is magnified by the impervious surfaces and hard shelters on the buildings.
However, with the emergence of a new discovery, these buildings can one day help clear the smoke from the air.
Smoke is unsightly, but more importantly, it can exacerbate lung and heart disease.
According to data from the World Health Organization, 3 million people worldwide die every year due to outdoor air pollution causing and exacerbating the disease.
In addition to reducing pollution sources that cause smog, eliminating existing air pollution is another useful measure.
A group of researchers found that combining graphene with titanium dioxide can degrade more than 70% of nitrogen oxides from the air compared to using titanium dioxide alone.
Titanium dioxide, also known as titanium dioxide , is a widely used natural ingredient that can be found in everything from paint to sunscreen.
It is also a nano-level photocatalyst, which can degrade nitrogen oxides and volatile organic compounds into harmless compounds in the sun.
Titanium dioxide researchers were able to create a graphene-titanium dioxide nanocomposite material that can be coated on a hard surface and can passively decompose air pollutants.
Then, the degraded components of air pollution may be washed away in rain or wind, and the process will not wear out the photocatalyst.
In addition to degrading nitrogen oxides, the researchers also found that this new compound can effectively degrade rhodamine B, which is similar to the molecular structure of vehicle air pollution.
Researchers say that before your factory becomes a smoky champion, a cheaper method is needed to produce graphene on a large scale, and further research is needed on how to make the coating be used for as long as possible in the actual built environment.
The research was published in the "Nanoscale" journal.
