Researchers convert atmospheric CO2 to carbon nanofibers and nanotubes for use as anodes in Li-ion and Na-ion batteries

Green Car Congress

Researchers from George Washington University and Vanderbilt University have demonstrated the conversion of atmospheric CO 2 into carbon nanofibers (CNFs) and carbon nanotubes (CNTs) for use as high-performance anodes in both lithium-ion and sodium-ion batteries. times above that of sodium-ion batteries with graphite electrodes.

Researchers develop new stable artificial photosynthesis device to produce ethylene and hydrogen from sunlight and CO2

Green Car Congress

A research team has developed a new artificial photosynthesis device component with remarkable stability and longevity as it selectively converts sunlight and carbon dioxide into two promising sources of renewable fuels: ethylene and hydrogen. We knew it was unstable—but we were surprised to learn just how unstable it really is.

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

Stuart Licht ( earlier post ) have developed a new process that transforms CO 2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes). The production of synthetic fuels from carbon dioxide (and/or water) has been widely studied and can be efficient. Licht et al.

Probing the effect of CO2 on Li-air batteries

Green Car Congress

A team of researchers in South Korea found that Li?air They suggested that the resulting mechanistic understanding of the chemistry of CO 2 in a Li–air cell and the interplay of CO 2 with electrolyte solvation will provide an important guideline for developing Li–air batteries. To develop a Li?“air” Earlier post.).

Volkswagen presents status of fleet study in electromobility; latest generation of twïnDRIVE plug-in hybrid

Green Car Congress

In parallel, more and more electricity is being generated from solar and water power. In addition, a scenario is being tested in which some of the daily peak electrical demand might be buffered by the cars’ lithium-ion batteries in the future. L/100 km (112 mpg US) is attained (equivalent to 49 g/km CO2). Li-ion packs.

China team engineers bacterium for photosynthetic production of ethanol from CO2

Green Car Congress

The resulting organism can directly convert carbon dioxide to ethanol in one single biological system. The effects of different culturing conditions including tap water, metal ions, and anoxic aeration on ethanol production were evaluated. A Synechocystis sp. 1 , 212 mg L ? coli to test ethanol-producing efficiency.
