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 drinking water and carbon-free energy. And scientists already have the technical ability to both desalinate seawater and split it to produce hydrogen, which is in demand as a source of clean energy.
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.D. Anderson Professor of physics at UH.
To tackle both stability and cost, the team developed a process to make use of nickel-iron-(oxy) hydroxide on nickel foam that is doped with a small amount of sulfur to generate an effective catalyst at room temperature in just 5 minutes. Since the catalyst works at room temperature, both the cost is reduced and the mechanical stability is enhanced, not

Shuo Chen), we looked at foreign direct investments (FDI) inflows into 224 Chinese cities at the prefecture level, from 2003 to 2010. We showed that the political term, as a core feature of career advancement in state bureaucracy, influences newly appointed government officials’ efforts to attract FDI.
In Chinese bureaucracy, large-scale leadership turnover happens every five years, right on the heels of the Party’s National Congress. Think of it as a window of opportunity for promotions, but with a few constraints. First, the law often mandates how many terms an official can serve in one specific position. Second, promotions are based on tournaments rewarding quantified economic objectives. Third, depending on their rank, officials must retire by age 55, 60 or 65. Under these rigid career progression rules, the optimal strategy is to keep moving before reaching retirement age.
