Scientists at EPFL have developed a scalable method to produce porous graphene membranes that efficiently separate carbon dioxide. The breakthrough could significantly reduce the cost and footprint of carbon capture technology.
Capturing carbon dioxide (CO₂) from industrial emissions is crucial in the fight against climate change. But current methods, like chemical absorption, are expensive and energy-intensive. Scientists have long eyed graphene—an atom-thin, ultra-strong material—as a promising alternative for gas separation, but making large-area, efficient graphene membranes has been a challenge.
Now, a team at EPFL, led by Professor Kumar Agrawal, head of the Gaznat Chair in Advanced Separations, has developed a scalable technique to create porous graphene membranes that selectively filter CO₂ from gas mixtures. Their approach slashes production costs while improving membrane quality and performance, paving the way for real-world applications in carbon capture and beyond.
