The two adjacent iridium atoms (dimer) are shown in green. The elements oxygen (O, red), barium (Ba, grey) and cerium (Ce, turquoise) are also involved in the crystal structure. Disclaimer ...

Iridium oxide catalysts are effective for water oxidation making them very attractive for green technologies. A team including researchers from SANKEN (The Institute of Scientific and Industrial ...

They achieved this by spreading individual iridium atoms on a piece of manganese oxide, preventing them from clumping together. With the new catalyst, hydrogen production was possible continuously ...
