Preparation of Macroporous Oxygen-deficient Titanium Oxide (Ti_nO_2n-1) from Titanium Hybrid Gel

Abstract

Oxygen-deficient titanium oxides (Ti_nO_2n-1) have attracted a lot of attention especially in electronics area due to their superior conductivity and chemical stability. In this study, monolithic Ti_nO_2n-1 materials with well-defined macropores have been synthesized from titanium hybrid gels which were prepared from titanium alkoxide and ethylenediamine via a nonaqueous so-gel reaction accompanied by phase separation. After the calcination in an inert atmosphere, macroporous Ti_nO_2n-1 materials were successfully obtained.
