The NMR relaxometrie gives acces to measure the longitudinal T1 and transverse T2 relaxation processes. This non-invasive technique has gained a lot of attention for studying surface interactions of liquids in saturated porous media .
Measurement of the values of T1 and T2 and determining the ratio T1/T2 gives insight in the strength of interaction between adsorbat and adsorbent .
We here measured several ionic liquids with aliphatic and aromatic groups on porous materials with and without catalyst loading to investigate their strenght of interaction with the solid material at the liquid-solid interface.
