UT El Paso-led team designs cactus-inspired low-cost, efficient water-splitting catalyst

Green Car Congress

Researchers led by engineers at The University of Texas at El Paso (UTEP) have proposed a low-cost, cactus-inspired nickel-based material to help split water more cheaply and efficiently. Nickel, however, is not as quick and effective at breaking down water into hydrogen. who led the study. Every day, I passed this same plant.

Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

A study by a team of researchers from Technische Universität Berlin (TUB) and Fritz-Haber-Institut der Max-Planck-Gesellschaft has found that direct seawater splitting for hydrogen production has substantial drawbacks compared to conventional water splitting and offers almost no advantage. Additionally, H 2 O is needed for water splitting.

Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Stanford researchers, with a colleague from King Fahd University of Petroleum and Minerals, have developed a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air. Water microdroplets are the hydrogen source for N 2 in contact with Fe 3 O 4. The conversion rate reaches 32.9 ± 1.38

New stable water-splitting catalyst doesn’t require expensive iridium

Green Car Congress

Researchers have developed a nickel-stabilized, ruthenium dioxide (Ni-RuO 2 ) anode catalyst for proton exchange membrane (PEM) water electrolysis. The Ni-RuO 2 catalyst shows high activity and durability in acidic OER for PEM water electrolysis. Illustration by Zhen-Yu Wu. 2 , suggesting potential for practical applications.

Tokyo Tech team develops high-performance bimetallic OER electrocatalyst for water splitting

Green Car Congress

A team led by researchers at Tokyo Institute of Technology (Tokyo Tech) have discovered a new bimetallic electrocatalyst for the oxygen evolution reaction (OER) in electrochemical water splitting: CaFe 2 O 4. In addition, the new OER boosting mechanism found in CaFe2O4 could lead to the engineering of other useful catalysts.

Novel inexpensive cobalt-nickel electrode for efficient water and urea electrolysis; yolk-shell nanoparticles

Green Car Congress

Both half reactions of water electrolysis—hydrogen and oxygen evolution—are unfortunately slow and require a lot of power. However, their large-scale use is impeded by high costs, limited abundance, and low stability. Sources of urea could include waste streams from industrial syntheses as well as sanitary sewage.

Ontario researchers develop new water plasmolysis method for production of hydrogen

Green Car Congress

Researchers at the University of Ontario Institute of Technology are developing a new method to dissociate water vapor into hydrogen gas by microwave-generated plasma (plasmolysis). In this study, a unique novel system is designed to decompose water vapor in a commercial modified 2.45 —Chehade et al. 2019.116831.
