Researchers at the University of Houston (UH), with colleagues from Central China Normal University and the Chinese University of Hong Kong, Hong Kong SAR, have developed a two-electrode catalyst that relies on one compound to produce hydrogen and oxygen efficiently from both seawater and freshwater. A paper on their work...
In recent years, hydrogen has gained a lot of attention as a potential clean energy source since it combusts without generating climate-damaging emissions.

New Catalyst Moves Seawater Desalination, Hydrogen Production Closer to Commercialization Fast, One-Step Assembly at Room Temperature Yields High Efficiency at Low Cost January 28, 2021 A team of researchers led by Zhifeng Ren, director of the Texas Center for Superconductivity at UH, has reported an oxygen evolving catalyst that takes just minutes to grow at room temperature and is capable of efficiently producing both clean drinking water and hydrogen from seawater. Seawater makes up about 96% of all water on earth, making it a tempting resource to meet the world’s growing need for clean ...
He added that quick, inexpensive production is highly significant for commercialization. Ren’s team of researchers and others have earlier reported a nickel-iron-(oxy)hydroxide compound as a catalyst to disintegrate seawater. However, generating the material demanded a long process at temperatures ranging between 300 °C and 600 °C, or as high as 1,100 °F. Due to the high energy cost, it was not viable for commercial use, and the high temperatures deteriorated the mechanical and structural integrity of the nickel foam, which made long-term stability a concern, stated Ren, who is also an M...
