Synthesis and Electronic Properties of Reduced Mesoporous Sodium Niobium Oxides

Abstract

A new series of electronically reduced mesoporous materialsbased on niobium oxide is reported. It is shown for the first time that, upon host–guest intercalation, electron transfer from the guest to the walls of the mesoporous host occurs whilst the porous structure of the material is retained (see Figure). The electronic properties of the host material are demonstrated to be tunable by addition of varying amounts of sodium.
