Maximizing Hydrogen Peroxide Formation during Water Electrolysis

Killing two birds with one stone

23-Jul-2024 - When water is split electrolytically, the result is typically hydrogen – and useless oxygen. Instead of oxygen, you can also produce a useful product. If you know how. Due to its high availability, water is considered the most useful starting material for hydrogen production. Ideally, the ...
