MIT researchers have found a new family of materials that provides the best-ever performance in a reaction called oxygen evolution, a key requirement for energy storage and delivery systems such as advanced fuel cells and lithium-air batteries.

The materials, called double perovskites, are a variant of a mineral that exists in abundance in the Earth's crust. Their remarkable ability to promote oxygen evolution in a water-splitting reaction — which breaks water molecules into oxygen and hydrogen — is detailed in a paper appearing in the journal Nature Communications.

This video shows the strong activity of the new catalyst material (dark circle at center) in promoting the oxygen evolution reaction when submerged in water, as revealed by the bubbles of oxygen forming on its surface.
