本工作采用新型钛源K2Ti4O9制备二氧化钛粉末。通过“低温溶解-再沉淀法”(LTDRP)，在50℃下反应48h，成功地合成了金红石型二氧化钛。所得样品的比表面积约为45m2/g，对NOx气体具有良好的光催化降解活性。金红石相二氧化钛与商品锐钛矿型二氧化钛的偶联对进一步提高光催化活性有显著作用。
This works employed K2Ti4O9, a novel Ti source, to prepare TiO2powders. By a “low-temperature dissolution–reprecipitation process” (LTDRP), rutile phase TiO2was successfully synthesized after reacting at 50°C for 48h. The obtained sample showed a specific surface area about 45m2/g, and excellent activity in photo-destruction of NOxgas. The coupling of rutile phase TiO2with commercial anatase TiO2showed significant effect in further enhancing the photocatalytic activity.
