Ruhr-Universitaet-Bochum researchers have boosted the efficiency of water electrolysis. They applied a layer of copper atoms to 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 […]

Stanford University scientists have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. Unlike other water splitters that use precious-metal catalysts, the electrodes in this device are made of inexpensive and abundant nickel and iron. Professor Hongjie Dai and colleagues have developed a cheap, emissions-free device that […]
