Catalysts accelerate chemical reactions, but the widely used metal platinum is scarce and expensive. Researchers at Eindhoven University of Technology (TU/e), together with Chinese, Singaporean and Japanese researchers, have now developed an alternative with a 20 times higher activity: a catalyst with hollow nanocages of an alloy of nickel and platinum. TU/e researcher Emiel Hensen wants to use this new catalyst to develop a refrigerator-size electrolyzer of about 10 megawatts in the future. The results will be published on November 15th in the journal Science.
