Water into fuel: The new nanomaterial that could upgrade green hydrogen

The Quick Take

Generating hydrogen without releasing carbon dioxide sounds simple: pass electricity through water, split water molecules and generate green hydrogen. The hard part is the electrocatalyst. The best ones rely on platinum, ruthenium and iridium, which are scarce and expensive. We wanted to know whether a small amount of iron and nickel oxides, anchored on carbon nanofibers grown by chemical vapor de
