(17)O Solid-State NMR Studies of Ta(2)O(5) Nanorods

[Image: see text] (17)O solid-state NMR spectroscopy was used to study the structure of Ta(2)O(5) nanorods for the first time. Although the observations of oxygen ions in the “bulk” part of the Ta(2)O(5) nanorods can be achieved with conventional high-temperature enrichment with (17)O(2), low-temper...

description [Image: see text] (17)O solid-state NMR spectroscopy was used to study the structure of Ta(2)O(5) nanorods for the first time. Although the observations of oxygen ions in the “bulk” part of the Ta(2)O(5) nanorods can be achieved with conventional high-temperature enrichment with (17)O(2), low-temperature isotopic labeling with H(2)(17)O generated samples whose surfaces are selectively enriched, leading to surface-only detection of oxygen species. By applying (17)O–(1)H double-resonance NMR techniques and (1)H NMR spectroscopy, surface hydroxyl species and adsorbed water can also be studied. The results form the basis for further understanding of the structure–property relationship of Ta(2)O(5) nanomaterials.
