Researchers at KTH have successfully tested a new material that can be used for cheap and large-scale production of hydrogen – a promising alternative to fossil fuel.
Precious metals are the standard catalyst material used for extracting hydrogen from water. The problem is these materials - such as platinum, ruthenium and iridium - are too costly to make the process viable. A team from KTH Royal Institute of Technology recently announced a breakthrough that could change the economics of a hydrogen economy.
Led by Licheng Sun, professor of molecular electronics at KTH Royal Institute of Technology, the researchers concluded that precious metals can be replaced by a much cheaper combination of nickel, iron and copper (NiFeCu).
"The new alloy can be used to split water into hydrogen,” says researcher Peili Zhang. “This catalyst becomes more efficient than the technologies available today, and significantly cheaper.
