摘要：

Nitrogen　doped　TiO2　nano-sized　powders　were　prepared　by　the　mechanochemical　reaction　method　and　the　property　of　the　powders　were　analyzed　and　characterized.　The　mixed　powder　of　doping　sources　hexamethylenetetramine　(HMT)　and　raw　TiO2　was　milled　by　high　energy　ball　mill.　The　prepared　powders　mainly　consist　of　anatase　and　brookite.　Compared　with　raw　material,　the　N-doped　powder　has　smaller　particle　size　and　larger　specific　surface　areas.　The　N-doped　powder　shows　excellent　absorption　for　visible　light　λ　＞　400　nm,　the　absorbed　band　＇red　shift＇　to　about　530　nm.
