In the blast furnace, it is so hot that carbon monoxide can be used, in place of carbon, to reduce the iron(III) oxide: iron(III) oxide + carbon monoxide → iron + carbon dioxide The blast ...

Fran visits a blast furnace where iron oxide is reduced to iron by carbon monoxide. The iron that is produced is called pig iron but this is brittle and must be processed into more useful types of ...

and discovered that these materials were remarkably active catalysts for the oxidation of carbon monoxide. He subsequently found that they comprised nanoparticles of gold supported on the oxide.
