Discovery is studied carefully when the light using wavelength less than 415nm irradiates TiO2 electrode, finds have oxygen to release on electrode.This is important
It is found to be people's research TiO2 photocatalytic activity and opens brand-new approach, established to also develop and use solar energy for the mankind
Basis.
Although TiO2 photocatalysis technology recent decades have obtained quick development, also there is also certain limitation,
In the photocatalysis technology of TiO2, so that receiving greatly constraint and limitation in actual application.Firstly, TiO2 is a kind of
Conductor oxidate, forbidden bandwidth is big, about 3.2eV, can only absorb the visible light for accounting for sunlight 4~5%, which limits
Utilization rate of the TiO2 photocatalysis technology to solar energy；Secondly, TiO2 photochemical catalyst be photohole and light induced electron it is compound in
The heart, photo-generated carrier is easy to be combined to again causes the activity of photochemical catalyst to be affected together, to make it actual
Using being above restricted.Hereafter, people have started to TiO2The study on the modification of catalysis material, TiO2Dual element doping be
A kind of raising TiO that nearest people inquire into2Photocatalytic activity doping way, currently, especially with respect to TiO2Dual element doping
Research do not have been reported that also, it is at high cost and because preparation process is complicated, it is modified that plated film should not be used as liquid (suspension)
Material.
