Description
Abu Talha Aqueel Ahmed and co-authors craft a cheap catalyst that splits water into hydrogen, in a 2024 study. Hydrogen fuel from water could store clean power at scale. The best catalysts lean on pricey platinum, which blocks wide use. Copper compounds are cheap but sluggish. The team grew a core-shell particle, copper oxide inside and copper sulfide outside, and laced it with nitrogen.
The new catalyst needed far less extra voltage to drive the reaction than plain copper sulfide. Its response slope was lower too, a sign of faster work. It ran for fifty hours at two current levels with no real fade. Tests traced the gains to quicker electron flow and more open active sites, both boosted by the nitrogen. The authors present the design as a path to platinum-free hydrogen gear.
