B-doped TiO₂ microspheres are prepared by the traditional hydrothermal method. The morphologies and microstructures of B-doped TiO₂ microspheres are characterized by FESEM, X-ray diffraction (XRD), UV-Vis and BET surface area measurements. The result shows that B doping may inhibit the crystal growth of TiO₂ anatase phase and also increase the specific surface area of B-doped TiO₂ microspheres, and the specific surface area is of 182.48 m²/g when B/Ti ratio is 0.6. B-doped TiO₂ microspheres show an enhanced photo-catalytic activity under the irradiation of visible light, which may totally photo-degrade the gaseous benzene within 70 min.

采用传统的水热法制备了B掺杂的TiO ₂微球。通过FESEM，X射线衍射（XRD），UV-Vis和BET表面积测量来表征B掺杂的TiO ₂微球的形貌和微结构。结果表明，B掺杂可抑制TiO ₂锐钛矿相的晶体生长，并增加B掺杂的TiO ₂微球的比表面积，当B / Ti比为0.6时，比表面积为182.48 m ² / g。 。B掺杂的TiO ₂微球在可见光的照射下表现出增强的光催化活性，可以在70分钟内完全光解气态苯。
