Researchers develop efficient single-atom Ni catalyst for conversion of CO2 to CO

Green Car Congress

While Ni metal catalyzes the hydrogen evolution reaction (HER) exclusively under CO 2 RR conditions, Ni single atomic sites present a high CO selectivity of 95% under an overpotential of 550 mV in water, and an excellent stability over 20 hours’ continuous electrolysis. The current density can be scaled up to more than 50 mA cm?2

New plasma synthesis process for one-step conversion of CO2 and methane into higher value fuel and chemicals

Green Car Congress

Researchers from the University of Liverpool (UK), with colleagues from Dalian University of Technology (China) and the University of Hull (UK), have developed a new process for the direct, one-step activation of carbon dioxide and methane (dry reforming of methane) into higher value liquid fuels and chemicals (e.g.,

Lux Research: cost of electrofuels remains far from viable

Green Car Congress

The cost of electrofuels—fuels produced by catalyst-based systems for light capture, water electrolysis, and catalytic conversion of carbon dioxide and hydrogen to liquid fuels—remains far away from viable, according to a new analysis by Lux Research. Production costs per barrel of oil equivalent. Source: Lux Research.

Stanford researchers develop copper-based catalyst that produces ethanol from CO at room temperature; potential for closed-loop CO2-to-fuel process

Green Car Congress

Researchers at Stanford University have developed a nanocrystalline copper material that produces multi-carbon oxygenates (ethanol, acetate and n-propanol) with up to 57% Faraday efficiency at modest potentials (–0.25?volts volts versus the reversible hydrogen electrode) in CO-saturated alkaline water. volts to –0.5?volts Christina W.

Iowa State team develops hybrid technology to create biorenewable nylon

Green Car Congress

Engineers at Iowa State University have developed a hybrid process that combines bio- and electrocatalysis to convert glucose into bio-based unsaturated nylon-6,6—which has the advantage of an extra double bond in its backbone that can be used to tailor the polymer’s properties. Hybrid conversion of glucose into UPA-6,6.

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. The energy savings come from not having to heat the substance to high temperatures.
