Innovations in Water Splitting

Hydrogen is considered a clean and renewable energy carrier, seen as a promising alternative to fossil fuels. One efficient and cost-effective method to produce hydrogen is through water splitting using light or electricity. This process involves the Hydrogen Evolution Reaction (HER), which requires a catalyst to lower the large overpotential. This review focuses on the mechanisms of hydrogen production using different catalysts, highlighting their efficiency and stability, and discussing future challenges and prospects.
