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.

NREL, Berkeley Lab propose efficiency and stability best-practices for solar water-splitting

Green Car Congress

Photoelectrochemical (PEC) water-splitting, which relies on sunlight to split water into oxygen and hydrogen, stands out as potentially one of the most sustainable routes to clean energy. PEC water-splitting was first noted in scientific publications in 1972. Photoelectrodes have demonstrated efficiencies from 10% to 20%.

MIT engineers create 2D polymer that self-assembles into sheets

Green Car Congress

Using a novel polymerization process, MIT chemical engineers have created a new two-dimensional polymer that self-assembles into sheets, unlike all other polymers which form one-dimensional chains. The new material is stronger than steel and as light as plastic, and can be easily manufactured in large quantities. —Michael Strano.
