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.

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 · 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10月26日 · Researchers at the University of California, Berkeley have invented a material in powder form that adsorbs carbon dioxide with astonishing performance. Just 200 g (a little under 0.5 lb) can suck...

2024年12月4日 · Scientists in California have created a new material, called COF-999, which can remove large amounts of carbon dioxide (CO2) from the air. The fluffy yellow powder works faster than other materials and can be used over and over again.

2024年11月8日 · Known as COF-999, the powder functions as a magnet that grabs and traps carbon dioxide from open air, even when the gas is present in small concentrations. The carbon dioxide can then be extracted from the material and pumped deep underground into porous rocks, sequestering it away from the atmosphere.

2024年11月25日 · The discovery of the powdery yellow COF-999 seems to be a more promising tool to help reduce the quantity of CO2 from the atmosphere. The material requires lower temperatures to release the gas than other processes, and it can be held until the CO2 is ready to be sequestered or repurposed.
