Researchers develop highly efficient organometal halide perovskite photoelectrodes for water splitting

Green Car Congress

Photoelectrochemical (PEC) water splitting based on solar energy is one promising approach for the production of green hydrogen. However, its widespread application is limited by a lack of efficient photoanodes for catalyzing the rate-limiting oxygen evolution reaction (OER), an important reaction in PEC water splitting.

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.

DOE awards $22.1M to 10 nuclear technology projects including clean hydrogen production

Green Car Congress

million to 10 industry-led projects to advance nuclear technologies, including two aimed at expanding clean hydrogen production with nuclear energy. A well-established downstream syngas-to-synfuel conversion process, such as Fischer-Tropsch synthesis, converts the syngas to liquid synfuel for a total projected cost of less than $4/gallon.

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.
