Researchers demonstrate new nickel selenide catalyst for more efficient water splitting

Green Car Congress

A team of researchers from Missouri University of Science and Technology and National and Kapodistrian University of Athens in Greece have developed a highly efficient transition metal selenide-based coordination complex, [Ni{(SePiPr 2 ) 2 N} 2 ] for oxygen evolution and hydrogen evolution reactions (OER and HER, respectively) in alkaline solution.

Researchers demonstrate electrochemical synthesis of ammonia from air and water under mild conditions

Green Car Congress

Researchers from the University of Strathclyde and the University of St. In industry, extensive purification of N 2 and H 2 is needed and this remarkably increases the overall cost of the process. is well known that some higher plants can synthesize ammonia or its derivatives directly from air and water at room temperature.

Single Pt atom catalysts show enhanced catalytic activity for water-splitting; potential to drive down electrolysis cost

Green Car Congress

A research team from University of Western Ontario, McMaster University and Beijing Computational Science Research Center has developed an effective synthesis method to produce isolated single platinum (Pt) atoms and clusters for use as catalysts for the hydrogen evolution reaction (HER) in water splitting to produce hydrogen.

NREL researchers capture excess photon energy to produce solar fuels; higher efficiency water-splitting for H2

Green Car Congress

The advancement could significantly boost the production of hydrogen from sunlight by using the cell to split water at a higher efficiency and lower cost than current photoelectrochemical approaches. The research is outlined in a paper in Nature Energy. Beard and other NREL scientists in 2011 published a paper in Science that.

Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

The improved catalyst has already released four times the amount of hydrogen ever produced by MoS 2 from water. Nevertheless, because of the scarcity and cost of Pt, a more abundant alternative is needed for cost-effective implementation. —co-author Jeff Brinker, Sandia Fellow and University of New Mexico professor.

MIT researchers develop optimized sulfidation separation process for rare earth and other key metals

Green Car Congress

Their sulfidation approach could reduce the capital costs of metal separation between 65 and 95 percent from mixed-metal oxides. Current methods of rare metal separation rely on large quantities of energy, water, acids, and organic solvents which have costly environmental impacts, says Stinn. Cite this article Stinn, C.,

Researchers take first 3D images of microscopic hydrogen-embrittled cracks in metal

Green Car Congress

Microfractures in metal alloys, though impossible to see with the naked eye, can easily spread when exposed to water or hydrogen and lead to major problems in structures such as bridges, electrochemical and nuclear plants and hydrogen storage containers, leading to failures and expensive repairs. ak & Michael J.
