鈦基體表面形成的納米管的內(nèi)徑可控制在50nm-150nm，納米管長(zhǎng)度可控制在200nm-500nm。通過(guò)離子注入和氮化處理方法可以實(shí)現(xiàn)對(duì)二氧化鈦納米管的非金屬摻雜，使其光響應(yīng)區(qū)域從紫外區(qū)拓寬到可見(jiàn)光區(qū)域。該技術(shù)形成的鈦制品或鍍有鈦膜的裝飾件置于室內(nèi)，在陽(yáng)光和日光燈照射下可凈化室內(nèi)空氣，降解空氣中甲醛等有害氣體。固定于汽車(chē)排氣管中可降解汽車(chē)尾氣中的有害氣體。置于污水處理器中利用可見(jiàn)光降解污水中難降解有機(jī)物，可對(duì)污水進(jìn)行深度凈化處理。
