Researchers have successfully split seawater without pre-treatment to produce green hydrogen.
The international team was led by the University of Adelaide’s Professor Shizhang Qiao and Associate Professor Yao Zheng from the School of Chemical Engineering.
Professor Qiao said, “We have split natural seawater into oxygen and hydrogen with nearly 100% efficiency, to produce green hydrogen by electrolysis, using a non-precious and cheap catalyst in a commercial electrolyser,” he said.
A typical non-precious catalyst is cobalt oxide with chromium oxide on its surface.
