The simple reason is that to generate hydrogen from water, the process requires a stable catalyst. The most reliable are expensive precious metals like platinum. However, a team of scientists from the University of Nottingham’s School of Chemistry and Faculty of Engineering may have found a solution – repurposed metal waste.

To their surprise, they found that the surfaces were not smooth at all but had “grooves and ridges that were only tens of nanometers wide.” They then realized that this “nanotextured surface could present a unique opportunity for the fabrication of electrocatalysts,” Frenandes stated.
