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

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. Resources Navid Attarzadeh, Debabrata Das, Srija N.

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.

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

Green Car Congress

Currently, the most efficient electrolyzers contain platinum and iridium, which are needed for the electrodes on which the hydrogen and oxygen gas are produced from water. That’s why we’re constantly looking for electrode materials made from more abundant resources which also can be used as efficient and stable electrocatalysts.

UNC team synthesizes silicon nanowires that split water

Green Car Congress

Researchers from the University of North Carolina have synthesized high-photovoltage multijunction Si nanowires (SiNWs) that are co-functionalized to split water catalytically. When integrated with the co-catalysts and suspended in water, these light-activated nanoreactors produced hydrogen gas under visible and infrared light.
