1·On its own, titania works best as a catalyst for this reaction in ultraviolet light.
格兰姆斯说，二氧化钛本身在紫外线下就是催化这个反应的良催化剂。
2·But adding nitrogen and copper to the mix shifts the preference of the titania tubes to visible light, Grimes says.
但是通过加入氮气和铜，会改变二氧化钛在可见光下的催化活性。
3·By controlling the hydration of alkoxide, and with n-butanol azeotropic distillation and ethanol rinsing methods, the preparation process of superfine titania powder was investigated in detail.
利用控制醇盐水解的方法，分别采用正丁醇共沸蒸馏和乙醇洗涤这两种工艺，详细研究了超细二氧化钛粉体的制备过程。
4·The basic principle of sputtering was presented, and the targets and techniques used in the preparation of titania thin film from sputtering were reviewed and discussed.
介绍了溅射法镀膜的基本原理，阐述了溅射法镀二氧化钛薄膜用靶材及相应溅射镀膜工艺的研究现状。
5·The liquid synthesis of nanocrystals titania at low temperature, due to avoiding the sintering process, brings superior physical and chemical properties.
低温液相合成晶态纳米二氧化钛由于避免了高温煅烧过程，可望赋予其更优越的特性。
