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...

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.

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.

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.

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.

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.

2025年1月15日 · UC Berkeley researchers have developed COF-999, a new material that absorbs CO₂ directly from the air without rapidly degrading. This breakthrough could be a game-changer for carbon capture.

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.

COF-999 는 2024년 10월 UC 버클리 의 오마르 야기 연구팀이 개발한 공유결합 유기 구조체 (Covalent Organic Framework)로 대기 중 이산화탄소 만을 아주 효율적으로 흡수하는 물질이다. 습도가 높은 환경에서는 훨씬 뛰어난 성능을 보이고 [2], 20분에 전체 흡수 가능량의 50% 1시간에 80%를 흡수한다, 60℃ 이상 가열하면 포집한 이산화탄소를 내뱉기 때문에 탄소 보관소만 따로 …

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.
