晶化良好的锐钛矿相纳米粒子的宽度约为50 nm。氮气吸附-脱附测试表明，产物具有26mg的高比表面积和丰富的介孔结构。将纳米二氧化钛空心球用于光催化降解溶液中的六价铬。结果表明，与其他结构的二氧化钛相比，二氧化钛的光催化活性有所提高，这是由于二氧化钛中空球具有较高的比表面积和丰富的介孔性质，此外，15
the width of well-crystallized anatase phase nanoflakes was ~50 nm. Nitrogen adsorption-desorption measurement revealed that the products had a high specific surface area of 26 m g and abundant mesoporous structure. The TiO2 hollow spheres were used to photocatalytic degrade Cr(VI) in solution. The results indicated an enhanced photocatalytic activity compared to the other structured TiO2, owing to the high specific surface area and abundant mesoporous properties of the TiO2 hollow spheres, besides, 15
