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. MoC produces an active interfacial structure for water dissociation, methanol activation, and successive reforming processes with compatible activity. 0c10776.

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.

Berkeley Lab leading investigation to quantify and characterize Salton Sea’s geothermal lithium resources

Green Car Congress

However, questions remain about the size of the resource, the potential rate of decline, the potential for regeneration, and sustainability of production. The Salton Sea geothermal system is the primary potential geothermal resource for lithium in the United States, and it’s a world-class resource. With nearly $1.2

Efficient recovery of lithium from spent LiFePO4 batteries via air oxidation–water leaching at room temperature

Green Car Congress

Researchers in China report using air oxidation–water leaching to recover lithium selectively from spent LiFePO 4 (LFP) material, in which the high leaching efficiency of lithium and the good separation effect of lithium and iron were achieved simultaneously. Earlier post.) Earlier post.) Hao Jin et al.

Study finds the wettability of porous electrode surfaces is key to making efficient water-splitting or carbon-capturing systems

Green Car Congress

As water-splitting technologies improve, often using porous electrode materials to provide greater surface areas for electrochemical reactions, their efficiency is often limited by the formation of bubbles that can block or clog the reactive surfaces. As a result, there were substantial changes of the transport overpotential. 2021.02.015.
