Researchers Discover Efficient New Way To Split Hydrogen From Water for Energy

Washington University in St. Louis researchers led by Gang Wu developed a platinum-free heterostructure catalyst for alkaline water electrolysis.

The catalyst combines rhenium phosphide and molybdenum phosphide and outperformed benchmark materials in hydrogen production.

It stayed stable for more than 1,000 hours at high current densities, showing strong durability for practical use.

The advance could cut reliance on costly platinum-group metals and make clean hydrogen cheaper and easier to scale.
