Scientists have found a way to transform metal waste into a highly efficient catalyst to make hydrogen from water, a discovery that could make hydrogen production more sustainable.
A team of researchers from the University of Nottingham's School of Chemistry and Faculty of Engineering have found that the surface of swarf, a byproduct of the metal machining industry, is textured with tiny steps and grooves on a nanoscale level. These textures can anchor atoms of platinum or cobalt, leading to an efficient electrocatalyst that can split water into hydrogen and oxygen.
The researchers used magnetron sputtering to create a platinum atom"rain" on the swarf's surface. These platinum atoms then come together into nanoparticles that fit snugly into the nanoscale grooves. The Zero Carbon Cluster has been set in the East Midlands to accelerate the development and deployment of innovation in green industries and advanced manufacturing.
