Abstract

Iron-based materials are among the most commonly usedoxygen scavengers.Here, we investigated the mesoporous silica nanosphere (MSN)-supportediron-based scavengers, such as FeO x nanoparticlesand different atomic layer deposition (ALD) coatings (FeO x and Fe). We found that the scavenger performanceis a result of a complex interplay between available Brunauer-Emmett-Tellersurface area and the scavenger composition, with the combination ofinfiltrated nanoparticles and Fe-ALD coating resulting in the bestperformance. When the glucose-based treatment of MSN is used to furtherenhance oxygen scavenging capacity, Fe-ALD coating yields the bestperformance, with a high oxygen adsorption capacity of 126.8 mL/g.ALD deposition of Fe represents a versatile method to introduce Fe-basedoxygen scavengers onto different supports, and it can facilitate theintegration of scavengers with different types of packaging, as thedeposition can be performed at a low temperature of 150 degrees C.
