In response to the challenge of the high cost of hydrogen production from electrolyzed water, Hainan University, in conjunction with the Ningbo Institute of Materials Technology and Engineering of the Chinese Academy of Sciences, broke through direct electrolysis of natural seawater to produce magnesium and achieve co-production of hydrogen and magnesium hydroxide, drastically reducing hydrogen production costs. On December 12, Beijing time, the relevant research results were published in the international academic journal “Nature Communications”. Researchers have developed a novel electrode like a “non-stick pan”. By adding iodine ions to the surface of the platinum electrode, electrostatic repulsive force is used to keep the magnesium hydroxide generated in the hydrogen analysis reaction of electrolyzed seawater away from the electrode surface and precipitate into the solution, effectively preventing the electrode surface from fouling. Currently, the seawater hydrogen and magnesium extraction engineering prototype developed by the research team can run stably in natural seawater for more than 5,000 hours.
