A zeolite foam able to capture carbon dioxide offers a uniquely durable and reusable method of trapping greenhouse gases.
The foam, developed by Chalmers University and Stockholm University, takes advantage of the ability of zeolite particles to adsorb carbon dioxide. Although zeolite particles have been typically difficult to work with, the foam developed by the team increases the surface area of the zeolites by using much smaller particles than usual. And because the particles are suspended in the foam matrix, they are more available to capture the CO2 as it passes through the filter.
According to the team, the zeolite foam is not only affordable, reusable durable and lightweight, but the captured CO2 can also be harvested for use in other products.
