Platinum-free catalyst splits hydrogen from water for energy, running 1,000 hours at industry standards

Phys · · 447 words · By Beth Miller

Researchers at Washington University in St. Louis developed a novel, platinum-free phosphide heterostructure catalyst for use in anion-exchange membrane water electrolyzers. This new catalyst was shown to efficiently split water into hydrogen and oxygen using renewable electricity. The study indicates the catalyst is highly durable, operating for over 1,000 hours under industry standards, making it a promising alternative to expensive platinum group metals.
