Hydrogen economy a step closer with water-splitting breakthrough
SYDNEY chemists may have removed one of the main hurdles to the “hydrogen economy” after developing what is believed to be the world’s most efficient water-splitting electrode.
The conductor, outlined overnight in an article in the journal Nature Communications, is made entirely of nickel and iron. Its inventors say it outperforms state-of-the-art electrodes based on iridium and ruthenium — metals so rare that only a few dozen tonnes are produced globally each year.
