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. —Song et al. Song et al.

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.

China team develops highly active catalyst for hydrogen production from methanol-water

Green Car Congress

Methanol–water reforming could prove to be a promising solution for hydrogen production/transportation in stationary and mobile hydrogen applications. A team from Peking University and colleagues have now developed a nickel-supported over face-centered cubic (fcc) phase ? Under optimized conditions, Ni/?-MoC 0c10776.

Uppsala team develops composite polymer dots for efficient, stable H2 production from water and sunlight

Green Car Congress

Researchers at Uppsala University have developed photocatalytic composite polymer nanoparticles (“polymer dots”) that show promising performance and stability for the production of hydrogen from water and sunlight. Since polymer dots (Pdots) are so tiny, they are evenly distributed in water. —Liu et al.

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

Green Car Congress

Electrolytic hydrogen production powered by renewable energy is seen as an environmentally friendly means to ameliorate global climate and energy problems. Both half reactions of water electrolysis—hydrogen and oxygen evolution—are unfortunately slow and require a lot of power. Zhang, S.L., and Lou, X.W.
