Abstract

In situ solid-state H1 NMR spectroscopy was employed to investigate the local chemical environments and dynamic details of protons in ZnO nanorods. The mean correlation time for the 4.8 ppm resonance was found to be ∼2.1× 10-10 s at 500 K and the activation energy for proton hopping was ∼0.15 eV. Both the small activation energy and short correlation time suggest that the protons are mobile. In contrast to nanometer micrometer particles of ZnO, γ- Al2 O3, and Ce O2, a stable resonance at 4.8 ppm indicates that these proton species are most likely associated with the defect sites in the lattice of ZnO nanorods.
