Schottky junction catalysts boost hydrogen production with non-precious metals in water electrolysis

Electricity-driven water electrolysis has garnered notable attention as an environmentally friendly method for hydrogen production, with high-purity hydrogen being crucial for addressing the energy crisis. Nonetheless, water electrolysis hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) typically require precious metals as electrocatalysts. This limitation has prompted researchers to focus on developing effective non-precious metal catalysts to enhance both the efficiency and cost-effectiveness of water electrolysis.
