The impressive capacity of various metal-organic framework (MOF) compounds to adsorb gases—especially toxic gases such as ammonia—has raised interest in these porous solids for use as gas-mask filtration materials. Filter materials are typically used as powders held in a canister fitted to the front of gas masks. But gas-mask designers aim to do away with the obtrusive canister, favoring instead a streamlined design in which the mask and filter are integrated into a low-profile unit. . . .
