Trash to treasure – researchers turn metal waste into catalyst for hydrogen
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 ...
