Characterization of a cobalt(II) cyanide complex inside zeolite Y that reversibly binds oxygen

Ordered mesoporous hybrid materials containing cobalt(ii) Schiff base complex

“…7), to determine the increase in dioxygen uptake resulting only from the active dioxygen binding complex. 48,49 The thermodynamic data presented in Table 6 clearly show that Co-fluomine incorporating materials exhibit a great affinity towards dioxygen with (P O 2 ) K (~1/K 1 ) varying from 1 to 6.9 Torr, and a total V O 2 adsorbed at 760 Torr ranging from 1.4 to 2.8 cm 3 g 21 .…”

Separation of Oxygen from Air Using Coordination Complexes: A Review

“…Recently, an anionic cobalt cyanide complex has been formed in zeolite Y by slurrying a CoY zeolite with a methanolic sodium cyanide solution (Taylor et al, 1989(Taylor et al, , 1992. Exposure to oxygen results in the formation of a C0-O2 adduct characterized by IR and EPR spectroscopy.…”

Cyclam complexes containing silica gels for dioxygen adsorption

“…In order to prepare stable dioxygen binding cobalt(II) complexes, metal derivatives were immobilised on various inorganic supports. For example amine, 5 cyanide, 6,7 polypyridine, 8,9 Schiff bases, [10][11][12][13] and porphyrin 14 cobalt complexes have been incorporated in the cavities of zeolites 7,9 or mesoporous silica. 13 However, the coordination scheme of the cobalt ion is not easily controlled and the materials are usually poorly loaded.…”
