Investigations under the transmission electron microscope of the Ba8Ni6Ge40 after 24 h as an OER catalyst show that the material has changed into a spongy Nickel network with a high surface area. The elemental analysis reveals that nearly all Germanium and Barium atoms have been washed out during this transformation.
