Table 1.

NMR parameters extracted from 95Mo QCPMG NMR spectra (acquired at 35.2 T) of 5Mo/ZSM-5 and 5Mo/ZSM-5 reacted for 60 min of MDA reaction.

Sample Component δiso(ppm) CQ(MHz) η
5Mo/ZSM-5 Mo-oxo − 35± 5 5.5 0.7~1.0
60min Mo-oxo − 35± 5 5.5 0.7~1.0
Mo2C/MoOxCy 800± 50 32 0.9

δiso: isotropic chemical shift, CQ: quadrupolar coupling constant, η: asymmetry factor.
