As you know, the most widespread element in the universe is hydrogen, which opens up truly unlimited possibilities for its use as an absolute ecological fuel, after which only heat and water remain.
However, access to these unlimited reserves is still closed due to the lack of efficient technologies. A significant step forward in this direction was the research of Stanford University chemists led by Hongji Dai. They have developed a water splitter made of nickel and iron and powered by a 1.5 volt battery.
According to one of the leading project specialists, graduate student Haotian Wang, when creating the splitter, nickel-iron oxide was used as a catalyst for both electrodes. It can split water for more than two weeks at room temperature with an efficiency of 82%.
Previously created splitters for splitting water, as a rule, used two electrolytes and electrodes made of expensive metals - platinum and nickel. The splitter developed at Stanford is much cheaper, more efficient and easier to manufacture than its counterparts.
Scientists are confident that their research will help solve the problem of producing hydrogen on an industrial scale, as well as in the search for new catalysts for other types of fuel.
