| Research Abstract |
Porous materials with nanometer-sized pores inside have functions such as adsorption, separation and catalysis. The properties of the inner surface of the nanospace are closely correlated with those functions. In the present study, we have aimed to establish a method to measure and evaluate the inner-surface properties of porous materials. We introduced probe molecules into the pores. We selected trimethylphosphine oxide (TMPO) as a probe molecule, and we have measured high-resolution solid-state NMR spectra. The acid strength was estimated from the 31P chemical shifts of the adsorbed TMPO, and the amount of the adsorbed TMPO was determined by the signal intensity of the 1H NMR signal. Thus, the acid properties of the porous materials with acid catalytic function are successfully evaluated.
