NMR cryoporometry and estimation of pore sizes in mesoporous silicon

Abstract

Nuclear magnetic resonance (NMR) cryoporometry is an experimental technique of structural characterization of mesoporous materials. In this contribution, different aspects of its application to study details of the pore structure in mesoporous silicon are presented. In particular, the information obtained with help of NMR cryoporometry is compared to that assessed using more conventional gas sorption techniques. The potentials of NMR cryoporometry to reveal fine details of the pore structure in intentionally multilayered mesoporous silicon are demonstrated.
