Clean energy future: New cheap and efficient electrode for splitting water

Scientists have developed a highly efficient oxygen-producing electrode for splitting water that has the potential to be scaled up for industrial production of the clean energy fuel, hydrogen. The new technology is based on an inexpensive, specially coated foam material that lets the bubbles of oxygen escape quickly. Unlike other water electrolyzers that use precious metals as catalysts, the electrode is made entirely from two non-precious and abundant metals -- nickel and iron.
