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.

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.

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. Prototype testing of Sparc Hydrogen’s reactor in real world conditions is the culmination of more than 5 years of research and development work conducted by the University of Adelaide and Flinders University.

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. who led the study. Every day, I passed this same plant.

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.

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.

Pitt engineers using membrane distillation to recycle water used in fracking and drilling

Green Car Congress

Engineers at the University of Pittsburgh Swanson School of Engineering are using membrane distillation technology to enable drillers to filter and reuse the produced water in the oil and gas industry, in agriculture, and other beneficial uses. The team is back in the lab to find a fix. Shamlou, Elmira & Vidic, Radisav & Khanna, Vikas.
