Noble metal-free catalyst system as active as platinum

The industry has been traditionally deploying platinum alloys as catalysts for oxygen reduction, which is for example essential in fuel cells or metal-air batteries. Expensive and rare, that metal imposes strict restrictions on manufacture. Researchers have discovered an alloy made up of five elements that is noble metal-free and as active as platinum. https://www.sciencedaily.com/releases/2018/10/181023110531.htm
