New porous coordination polymer captures CO2, converts it to useful organic materials

Green Car Congress

The new material is a porous coordination polymer (PCP, also known as MOF; metal-organic framework), a framework consisting of zinc metal ions. However, weak gas-binding ability and/or poor sample crystallinity after guest exchange hindered the development of efficient materials for CO 2 incorporation, activation and conversion.

New polymer membrane efficiently removes carbon dioxide from mixed gases; high permeability and selectivity

Green Car Congress

A team of researchers from North Carolina State University, SINTEF in Norway and the Norwegian University of Science and Technology, has developed a polymer membrane technology that removes carbon dioxide from mixed gases with both high permeability and high selectivity. the ability to separate one gas from another.

NSF awards $2M to Rice U collaboration to explore direct conversion of CO2 into fuels

Green Car Congress

There is still a lack of new redox-active carbon dioxide carriers for effective electrochemical carbon dioxide capture from such point sources as flue gas. We include experts in catalysts and electrolyzer design, polymer engineering, density functional theory simulations and carbon dioxide capture. —Haotian Wang.

New system for more efficient CO2 electrolysis to hydrocarbon products

Green Car Congress

The researchers combined a copper electrocatalyst with an ionomer [polymers that conduct ions and water] assembly that intersperses sulfonate-lined paths for the H 2 O with fluorocarbon channels for the CO 2. Here, we present a catalyst:ionomer bulk heterojunction (CIBH) architecture that decouples gas, ion, and electron transport.

MIT researchers propose mechanism for overcoming bottleneck in electroreduction of CO2

Green Car Congress

The findings could spur progress on developing a variety of materials and designs for electrochemical carbon dioxide conversion systems. For the latter, two main contributions are distinguished: gas depletion due to CO 2 consumption and ion generation in areas close to the electrocatalyst surface. —Soto et al.

UT Arlington researchers use polyaniline to split CO2 into alcohols

Green Car Congress

Researchers at The University of Texas at Arlington have been the first to demonstrate that polyaniline (PANI), a member of the organic conducting polymer family, is a promising photocathode material for the conversion of carbon dioxide into alcohol fuels without the need for a co-catalyst.

Researchers develop solid electrolyte for electrocatalytic reduction of CO2 to pure liquid fuels

Green Car Congress

Now a team led by researchers at Rice University has achieved continuous electrocatalytic conversion of CO 2 to pure liquid fuel solutions in cells that utilize solid electrolytes, in which electrochemically generated cations (such as H + ) and anions (such as HCOO ? ) Schematic illustration of the CO 2 reduction cell with solid electrolyte.
