NMR spectra were recorded on Bruker 400 Avance III HD equipped with a BBI-z grad probe head 5 mm.
High-Resolution Mass Spectra (HRMS) were collected using a Waters GCT gas chromatograph coupled with an electron ionization time-of-flight mass spectrometer (GC/MS-TOF).
FTIR spectra were obtained with solid samples on a Nicolet 5700 FT-IR instrument in ATR mode.
NH3-temperature programmed desorption (NH3-TPD) measurements were carried out on a TPDRO-1100-Omnistar with a thermal conductivity detector (TCD).
The in situ FTIR spectra during desorption of pyridine were measured on a Thermo Nicolet 380 FTIR spectrometer.
Thermogravimetric analyses (TGA) of samples were performed on a Q5000 IR instrument (TA Instruments) and collected in N2 or air upon equilibration at 100 °C, with a subsequent temperature ramp (10 °C/min) up to 1000 °C.
