Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Water (H 2 O) microdroplets are sprayed onto a magnetic iron oxide (Fe 3 O 4 ) and Nafion-coated graphite mesh using compressed N 2 or air as the nebulizing gas. This gas–liquid–solid heterogeneous catalytic system synthesizes ammonia in 0.2 The conversion rate reaches 32.9 ± 1.38 —Song et al. 2301206120

Researchers develop earth-abundant photocatalyst for conversion of ammonia into hydrogen

Green Car Congress

This result demonstrates the potential for highly efficient, electrically driven production of hydrogen from an ammonia carrier with earth-abundant transition metals. The new catalyst breaks those molecules into hydrogen gas and nitrogen gas, the largest component of Earth’s atmosphere. —Yuan et al.

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity. unusually high electrical conductivity and Raman spectra of these materials demonstrated in the linked Data in Brief paper are that of multi-walled carbon nanotubes, and are due to the morphology as demonstrated by TEM.

DOE launches Clean Fuels & Products Shot

Green Car Congress

The US Department of Energy (DOE) launched the Clean Fuels & Products Shot , a new initiative that aims to reduce greenhouse gas emissions (GHGs) from carbon-based fuels and products significantly. Biomass and waste conversion technologies designed to use green electricity and hydrogen to maximize carbon retention in products.

Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.
