The first direct probing of porosity on supported mesoporous silica thin films through hyperpolarised129Xe NMR

Abstract

The continuous flow hyperpolarised (HP) 129Xe NMR technique has been used for the first time on mesoporous silica thin films. This study demonstrates the possibility of recording information about the porosity of a very small quantity of materials and the high sensitivity of the NMR response to pore size and pore functionality.
