Solid-state MAS NMR detection of the oxidation center in TS-1 zeolite by in situ probe reaction

In this paper, the oxidation of trimethylphosphine as an in situ probe reaction was performed to monitor the oxidation ability of different Ti species in TS-1 zeolite by 31P MAS NMR spectra, which found for the first time direct evidence about the oxidation center of TS-1 zeolite.
