纳米二氧化钛制备及其有机物定性检测研究

Synthesis of Nano-TiO_2 and its Qualitative Determination to Organic Materials

通过牺牲碳球模板合成了内含金核的二氧化钛空心球。这种新颖的核壳结构能够在3分钟内对亚甲基蓝催化降解率达到40%左右,20分钟左右亚甲基蓝催化降解率达到97%左右,可以很好的应用于蒽醌类有机物的快速定性检测,具有良好的应用前景。

Uniform hollow Au@ TiO2 core shell spheres with moveable Au nanoparticles were synthesized based on templating against Au@ carbon spheres. The prepared hollow Au@ TiO2 core - shell spheres display enhanced photocatalytic activity in the initial stage of photocatalytic degradation of methylene, which could lead to potential applications in the testing origanic materials.
