When most people think of rust, a naturally occurring byproduct of iron or steel interacting with water, they don’t see it as good thing. West Virginia University’s Nick Wu isn’t most people.
“While most people see rust as an everyday nuisance, scientists have shown that by re-engineering its structure, it can become a very powerful material for splitting water to generate hydrogen gas,” said Wu, an associate professor of mechanical and aerospace engineering in the Statler College of Engineering and Mineral Resources. “Solar-to-hydrogen conversion is very similar to a solar panel creating electricity, only now the final product is hydrogen gas, which can be easily stored and transported for long-term use.”
