 Mixed metal oxide electrode

Mixed metal oxide electrodes (MMO electrodes) are types of electrodes that consist of a combination of different metal oxides, typically including noble metals and transition metals. These electrodes are widely used in various electrochemical applications such as electrocatalysis, water treatment, and energy conversion technologies (like fuel cells and electrolyzers). ### Key Features and Characteristics: 1. **Composition**: MMO electrodes often include metals like ruthenium, iridium, titanium, and tantalum, among others.
