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. Boyang Li of the University of Pittsburgh is co-lead author of the paper.

Sparc Hydrogen to test photocatalytic water splitting (PWS) reactor at CSIRO

Green Car Congress

The Sparc Green Hydrogen process combines concentrated solar (CS) with photocatalytic water splitting. The key aims of this work are to advance the technology readiness level (TRL) of Sparc Hydrogen’s PWS reactor and provide valuable data and information for the subsequent piloting phase.

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.

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. The material can be used as either an anode or a cathode, and demonstrates high activity and stability in the production of hydrogen and oxygen in the electrolysis of water. Zhang, S.L., and Lou, X.W.

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.
