Nearest several years, expose not coplanar TiO2Article in terms of nanocrystalline nanostructured in other words is very more, Hui
Ming Cheng et al. are prepared for the TiO of the different crystal faces of micron-sized exposure2, then test their photocatalytic activity.He
Result show, TiO2{ 100 } compared to { 101 } and { 001 } with higher activity.They are attributed to difference reason
Crystal face there is different level structures, and the co-ordination state of surface atom.But it is clear that such explanation can not allow people
It is satisfied, the TiO that they use2Sample is all that micron is brilliant, and actually used TiO2Photocatalyst also has very big difference.
It was found that most of method can only prepare the TiO of hundreds of nanometer of exposure particular crystal plane to several micron-scales2Receive
Meter Jing, and for the TiO of tens nano-scales2It is nanocrystalline then helpless.Therefore, it is necessary to developing one kind prepares TiO2Nanometer
Brilliant method, can regulate and control TiO2Nanocrystalline exposure crystal face, this will be research TiO2Catalytic property the catalysis of one model is provided
Agent, while being also beneficial to develop highly active TiO2Catalysis material.
