Abstract:
1. A process for removing oxygen from a non-air gaseous system comprising oxygen, said process comprising the steps of: providing a transition metal complex selected from the group consisting of a transition metal complexed with a salen, saltin, salophen, or salcyhexen ligand; forming a solution including at least one solvent and said transition metal complex; spraying said solution containing said at least one solvent and transition metal complex through a nozzle into an antisolvent; generating atomized droplets of said solution; and contacting droplets with the antisolvent to form a nanoparticulate solid transition metal complex absorbent; exposing said gaseous system to said nanoparticulate solid transition metal complex absorbent, wherein said absorbent is capable of absorbing oxygen, at a temperature less than about 100° C.
