Efficiency of water electrolysis doubled

Researchers have boosted the efficiency of water electrolysis. They applied a layer of copper atoms in a conventional platinum electrode. Thus, reaction intermediates could desorb a bit more easily from the catalyst surface. The modified system generated twice the amount of hydrogen than a platinum electrode without a copper layer. The team from the Ruhr-Universität Bochum, Technical University in Munich and Universiteit Leiden published these results in the journal Nature Communications.
