Researchers from RMIT and the University of Melbourne have discovered high-frequency vibrations can release 14 times more hydrogen compared with standard electrolysis techniques.
The discovery also has ramifications for the expensive, rare materials currently used in electrolysers. “With sound waves making it much easier to extract hydrogen from water, it eliminates the need to use corrosive electrolytes and expensive electrodes such as platinum or iridium,” research lead Amgad Rezk said. December 13, 2022 Bella PeacockMelbourne researchers have discovered sound waves can be used to “divide and conquer” water molecules during electrolysis, a process where electricity runs between two electrodes to split H2O molecules into oxygen and hydrogen gases which appear as bubbles.“The electrical output of the electrolysis with sound waves was about 14 times greater than electrolysis…
