A good catch of CO 2 ! It is demonstrated for the first time that a high‐surface‐area, inorganic‐based mesoporous silicon nitride prepared through a precipitation–sublimation route shows a high, reversible CO 2 uptake over a wide temperature range (298–423 K) with a moderate heat of adsorption. Our data render the thermally stable material a new contender for practical CO 2 capture.
