离子掺杂对纳米二氧化钛晶型转变的影响

Effects of Ions on the Phase-transformation of Nano-TiO_2 Particles

综述了不同阳离子和阴离子掺杂对二氧化钛由锐钛矿型向金红石型转化(A→R相变)的影响以及该领域现存的几个主要问题,并且提出了该领域进一步的发展方向。

Nanometer rutile TiO2 has been obtained extensive interesting to its preparation owing to its excellent physical performance, chemical properties and widely application prospects. Characteristics of three types of titania were briefly introduced and the effects of various cations and anions on the anantase to rutile phase-transformation of nanometer TiO2 particals were systematically reviewed，Three main unsolved problems in the present studies and farther research direction were put forward。
