Research Abstract

(1) Cobalt phthalocyanine (Co(II)Ph) complexes were synthesized inside the large cavities of Y-type and MCM41-type zeolites. A formation of the oxygen molecule adducts was clearly observed in both zeolites with Co(II)Ph by ESR method when O_2 molecules were introduced into the CoPc complexes with ammonia, ter-buthylamine and other amines as an axial ligand. Number of the oxygen molecules adducted to Co(II)Pc was studied as a function of axial ligands, oxygen pressures, temperatures, and others. The optimized conditions of O_2 absorption-desoption on the CoPc fixed were discussed based on the experimental results. Furthermore, the reversibility of the O_2 adsorption-desorption reactions and the diffusion and stabilization of un-reacted O_2 molecules were discussed in terms of the stability and bulkiness of the axial ligand used.
(2) Effects of axial ligands out O_2/N_2 selectivities of oxygen facilitated transport membranes containing a Co(II)-complex, N,N-bis(3-methoxysalicylidene)-2-methylpropylenediaminato-Co(II), was studied using 4-dimethylaminopyridine (4-DMAP), dimethyl sulfoxide (DMSO) and pyrazine as an axial ligand. The O_2/N_2 selectivities of the membranes resulted in 160, 3 and 2.2, respectively. Based on the results the reaction mechanisms were discussed in terms of oxygenetion and deoxygenation raters.
(3) Paramagnetic NO_x(x=1.2) molecules adsorbed on metal ion exchanged zeolites were studied in order to get fundamental information about the relations between the adsorption-desorption reactions and the static-dynamic structures of gaseous molecule related to O_2 in micro-porous crystals.
