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. The conversion rate reaches 32.9 ± 1.38 Water microdroplets are the hydrogen source for N 2 in contact with Fe 3 O 4.

Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

A study by a team of researchers from Technische Universität Berlin (TUB) and Fritz-Haber-Institut der Max-Planck-Gesellschaft has found that direct seawater splitting for hydrogen production has substantial drawbacks compared to conventional water splitting and offers almost no advantage. Additionally, H 2 O is needed for water splitting.

DGIST-led team improves efficiency of photocatalyst for conversion of atmospheric CO2 to hydrocarbon fuels

Green Car Congress

Scientists are investigating their use to trap carbon dioxide from the atmosphere as one of many means to alleviate global warming. Carbon dioxide gas and water vapor moved through the chamber, passing over the catalyst. Photocatalysts are semiconducting materials that can use the energy from sunlight to catalyze a chemical reaction.

Cryo-imaging reveals how fuel cell platinum catalyst layers could be optimized for efficiency

Green Car Congress

There is therefore a pressing global need to develop catalysts that can generate the most power while minimizing platinum content. Most proton-exchange membrane fuel cells (PEMFC) catalysts contain platinum—a scarce and precious metal. Manufacturers integrate these catalysts in complex assemblies called catalyst layers.
