An oxygen evolution reaction catalyst is a ternary metal oxide that includes Mn and is represented by MnSbOin the rutile crystal phase and MMnOwhere M is selected from the group consisting of Ca, Ni, Sr, Zn, Mg, Ni, Ba, Co and where u/(u+v) is greater than 33%.

Oxygen evolution reaction catalysis

An Oxygen Evolution Reaction (OER) catalyst includes a metal oxide that includes oxygen, cerium, and one or more second metals. In some instances, the cerium is 10 to 80 molar % of the metals in the metal oxide and/or the catalyst includes two or more second metals. The OER catalyst can be included in or on an electrode. The electrode can be arranged in an oxygen evolution system such that the Oxygen Evolution Reaction occurs at the electrode.

Described herein are systems and methods method for forming semiconductor films. In some embodiment, the methods comprising depositing the source solution containing a solvent and plurality of types of metal ionic species and a second type on a substrate heated to a temperature at or above the boiling point of the solvent. In some embodiments, methods and apparatus for exposing a substrate to a gas are also provided.
