Abstract : |
The cobalt-doped aluminophosphate molecular sieve, CoAPO-34 (with the chabazite-type topology) was prepared under ionothermal conditions using 1-ethyl-3-methylimidazolium bromide (EMIMBr) ionic liquid in presence of 1,6-hexanediamine (HDA). The HDA is not incorporated in CoAPO-34, but is required to mediate the availability of Co2þ during the synthesis. The material was characterized using powder Xray diffraction (PXRD), thermogravimetric analysis (TGA) and solid-state NMR spectroscopy. Wideline 31P NMR spectroscopy showed broad signals (~5000e10000 ppm wide), confirming that paramagnetic cobalt ions are successfully incorporated within the framework of the materials. |
