A material that splits water into oxygen and hydrogen at room temperature using relatively little electricity could be an important step toward affordable chemical storage of solar power. (newscientist.com)
Specifically, the researchers used graphene oxide, a form of the material made up of carbon, oxygen and hydrogen atoms. (newatlas.com)
A chemical reaction between oxygen and hydrogen produces the electric power, and when the transportation fuel is pure hydrogen, the only resulting emission is water vapor. (transportation.gov)
