Kvr. Chary et al., CHARACTERIZATION OF MOO3 TIO2 CATALYSTS BY H-1 MAGIC-ANGLE-SPINNING NMR-SPECTROSCOPY/, Journal of molecular catalysis. A, Chemical, 96(1), 1995, pp. 5-8
H-1 MAS NMR spectra of molybdenum oxide catalysts supported on anatase
and rutile polymorphs of TiO2 reveals the presence of two types of OH
groups (acidic and basic) on the surface of TiO2.
