AI Summary

Researchers tested a new electrocatalyst made from small amounts of iron and nickel oxides anchored on carbon nanofibers grown by chemical vapor deposition. The catalyst was designed to replace scarce and expensive platinum, ruthenium, and iridium used in current green hydrogen production. The study, published in ACS Applied Nano Materials, shows the iron‑nickel nanomaterial can drive both the oxygen evolution reaction at the anode and the hydrogen evolution reaction at the cathode. This could enable more affordable, scalable water‑splitting for green hydrogen, which currently supplies only a small fraction of the 96 % of hydrogen produced from fossil fuels.
