Title: The role of NH{sub 3} atmosphere in preparing nitrogen-doped TiO{sub 2} by mechanochemical reaction

Abstract

NH{sub 3} atmosphere in ball milling plays an important role in preparing TiO{sub 2-} {sub X} N {sub X} by a simple mechanochemical reaction. The results show that the structure transformation of titania milled in NH{sub 3} is greatly delayed compared with that in air. The specific surface area of titania milled in NH{sub 3} for 2 h is two times larger than that in air. It was also found that titania prepared in NH{sub 3} has obvious absorbance for visible light. Mechanochemical milling in NH{sub 3} atmosphere offers a new route to prepare TiO{sub 2-} {sub X} N {sub X} with high surface area. -- Graphical Abstract: The specific surface area (BET) of titania varies with the increase of milling time in air and gaseous ammonia.
