Structure of a paramagnetic supermicroporous silica-based material via a multinuclear solid-state NMR monitoring. Academic Article

abstract

• The paramagnetic Si/Al material doped with 19.8% (weight) of Mn2+ has been characterized by the 1H, 13C, 27Al, 29Si MAS NMR spectra and the 1H, 29Si T1MAS relaxation measurements as a gel dried at 130 degrees C and as samples calcined at 504, 540 and 650 degrees C. It has been demonstrated that in spite of strong paramagnetic effects, NMR monitoring in combination with 29Si T1 relaxation experiments can be successful for structural descriptions of porous materials.
