Title: Effects of Calcination Condition on Porous Reduced Titanium Oxides and Oxynitrides via Preceramic Polymer Route

The preceramic polymer route from titanium-based inorganic-organic hybrid networks provides electro conductive N-doped reduced titanium oxides (TinO2nā€“1) and titanium oxynitrides (TiOxNy) with a monolithic shape as well as well-defined porous structure. This methodology demonstrates advantageously lower temperature of crystal phase transition compared to the reduction of TiO2 by carbon or H2. In this study, effects of calcination condition on various features of the products have been explored by adopting three different atmospheric conditions and varying the calcination temperature. The detailed crystallographic and elemental analyses disclose the distinguished difference in phase transition behavior with respect to calcination atmosphere. Correlation between the crystallization and nitridation behaviors, porous properties and electric conductivities in the final products has been discussed.
