EPFL team's new method enables scalable CO2-selective porous single-layer graphene membranes

A team of researchers at École Polytechnique Fédérale de Lausanne (EPFL) recently developed a scalable technique to create porous graphene membranes that selectively filter CO₂ from gas mixtures. Their approach is said to reduce production costs while improving membrane quality and performance, paving the way for real-world applications in carbon capture and beyond.

Graphene membranes are excellent at separating gases because they can be engineered with pores just the right size to let CO₂ through while blocking larger molecules like nitrogen. This makes them ideal for capturing CO₂ emissions from power plants and industrial processes. But there’s a catch: manufacturing these membranes at a meaningful scale has been difficult and costly.
