"Transforming Metal Waste into Hydrogen Catalyst: A Sustainable Solution"

Researchers at the University of Nottingham have discovered a way to repurpose metal waste, specifically swarf from the metal machining industry, into a highly efficient catalyst for producing hydrogen from water. By utilizing the nanoscale textures on the surface of swarf, the team was able to anchor platinum or cobalt atoms, creating an effective electrocatalyst for water splitting. This breakthrough could lead to more sustainable hydrogen production, addressing the challenge of limited and expensive precious metals typically used in the process.
