Chemical processes on solid surfaces. What is so important about rusty iron?
I am browsing several available reports that I googled right away but do not find an answer I really understand - so let's just accept the fact:
"Ertl's research laid the foundation of modern surface chemistry, which has helped explain how fuel cells work, how catalytic converters clean up car exhaust (...) Surface chemistry can even explain the destruction of the ozone layer as vital steps in the reaction actually take place on the surfaces of small crystals of ice in the stratosphere," the award citation said.
