Researchers develop highly efficient organometal halide perovskite photoelectrodes for water splitting

Green Car Congress

Photoelectrochemical (PEC) water splitting based on solar energy is one promising approach for the production of green hydrogen. However, its widespread application is limited by a lack of efficient photoanodes for catalyzing the rate-limiting oxygen evolution reaction (OER), an important reaction in PEC 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

Audi plans to cut water consumption in production in half by 2035

Green Car Congress

Audi has included the economical and efficient use of water as a key aspect of its Mission:Zero environmental program. The company plans to keep its own water consumption to a minimum and stop using drinking water in vehicle production in the future. Drinking water is a valuable and scarce resource: 2.2

High-entropy oxide as high-activity electrocatalyst for water oxidation

Green Car Congress

Researchers from the University of Twente in The Netherlands have developed a new high-entropy perovskite oxide (HEO) as a high-activity electrocatalyst for the oxygen evolution reaction (OER)—the key kinetically limiting half-reaction in several electrochemical energy conversion technologies, including green hydrogen generation.

Researchers split seawater without pre-treatment to produce green hydrogen

Green Car Congress

Researchers from the University of Adelaide and Tianjin University have successfully split seawater without pre-treatment to produce green hydrogen. The use of vast amounts of high-purity water for hydrogen production may aggravate the shortage of freshwater resources. Resources Guo, J., Zheng, Y.,

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.

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.
