Catalytic Coating Makes Pollution-Eating Billboards

I write in praise of air. I was six or five
when a conjurer opened my knotted fist
and I held in my palm the whole of the sky.
I’ve carried it with me ever since.

That is the opening stanza from “In Praise of Air” by British poet, playwright and novelist Simon Armitage.

There’s beauty to this poem that goes beyond the ideas it conveys and the careful craftsmanship of the writer. The work doesn’t just praise the air, it clears it.

Or, more accurately, the 65-foot-high banner upon which the poem is printed clears it. That’s because the material is coated with nanotechnology that chews up airborne pollutants.

In Praise of Air, a collaboration between Armitage and physical chemistry professor Tony Ryan, has been unfurled on a building at the University of Sheffield in the UK to bring attention to Ryan’s innovation.
