Abstract

Hydrogen is the cleanest fuel source, and its production via water electrolysis is crucial. To improve the sustainability and practicality of water splitting, developing effective electrolysis catalysts is essential. Current commercial Pt/C catalysts face challenges with limited durability and high production costs, making them unsuitable for long-term use. Therefore, creating high-performance, low-cost, and stable catalysts with high catalytic activity is vital for advancing the hydrogen production industry. Multi-metallic oxide catalysts, which leverage the synergistic effects of multiple metals, can significantly enhance stability. Moreover, the flexibility of multi-metallic systems to modify electronic and crystal structures offers substantial potential for catalyst optimization, making them a key focus for developing stable water electrolysis catalysts. This report will explore recent applications of multi-metallic oxides in water electrolysis, emphasizing their role in improving catalyst stability.
