Various materials can capture carbon from the air by utilizing changes in humidity, CGTN, April 7, 2025, 10:16. A recent study conducted by scientists at Northwestern University in the United States shows that there are many materials that are inexpensive and widely available, and which can be used to capture carbon directly from the air by taking advantage of changes in humidity. They call it “one of the most promising methods for carbon dioxide capture.” The related paper was published in the latest issue of the journal Environmental Science and Technology. The research team emphasized that traditional direct air capture technologies lack competitiveness due to high costs and technical complexity. The materials involved in the latest platform can be used almost anywhere and can work in conjunction with other systems, offering the potential to contribute to global efforts to reduce emissions.
