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.

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
