Carbon dioxide capture from open air using covalent organic …
2024年10月23日 · In this study, we designed a porous, crystalline COF (termed COF-999) that selectively captures 2.05 mmol of CO 2 per gram sorbent from air containing 400 ppm of CO 2 at 50% relative humidity...
Capturing carbon from the air just got easier - Berkeley News
2024年10月23日 · The new porous material for capturing carbon dioxide, called a covalent organic framework (COF), has hexagonal channels decorated with polyamines that efficiently bind carbon dioxide molecules (blue and orange balls) at concentrations found in ambient air.
Exotic Powder Pulls Carbon Dioxide from the Air at a Record Rate
2024年11月19日 · When Zhou and Yaghi pumped air through a tube packed with COF-999, the powder captured CO 2 at the fastest rate ever measured, the researchers reported in Nature.
This New, Yellow Powder Quickly Pulls Carbon Dioxide From the …
2024年11月22日 · The porous material, known as a covalent organic framework, is called COF-999. Within the framework are compounds called amines, which have a basic pH.
Carbon capture COF shows impressive ability to survive hundreds …
2024年11月6日 · Researchers at the University of California, Berkeley, have synthesised a new material, COF-999, that can capture carbon dioxide from air and remains both chemically and thermally stable even after 100 cycles of capture and regeneration.
This powder removes as much CO₂ from the air as a tree - Los …
2024年10月23日 · Dubbed COF-999, the powder could be deployed in the kinds of large-scale direct air-capture plants that are starting to come online to reduce the amount of carbon in the atmosphere.
Covalent organic framework captures carbon from air
2024年10月24日 · In dry air, 1 g of COF-999 can take up 1 mmol of CO 2 from a gas mixture containing 400 ppm CO 2; at 50% humidity, the capacity is just over 2 mmol/g. Heating the COF to 60 °C will release the captured CO 2, freeing up the material to capture more carbon.
200 grams of this incredible powder can pull as much CO2 out of …
2024年10月28日 · UC Berkeley chemists develop COF-999, a breakthrough material for direct air carbon capture, promising more efficient CO2 removal from the atmosphere.
Half a pound of this powder can remove as much CO2 from the air …
2024年10月23日 · Now scientists at UC Berkeley say they can do the same job with less than half a pound of a fluffy yellow powder. The powder was designed to trap the greenhouse gas in its microscopic pores, then release it when it’s ready to be squirreled away someplace where it can’t contribute to global warming.
A half-pound of this yellow powder can capture as much CO2 as a …
2024年10月24日 · Direct air capture technology — machines that suck CO2 from the atmosphere — is emerging as one possible solution. The yellow powder, COF-999, could supercharge this effort. Packed with...
