Ore deposit and three kinds of structures of cubic zinc blende.Under field conditions (factors), cube buergerite and cubic rock ore deposit structure are at meta shape
State, so zinc oxide（ZnO）It is to be existed with the symmetrical wurtzite structure of six sides.Due to zinc oxide（ZnO）There is wider forbidden band
Width（3.37eV）, so zinc oxide（ZnO）It is a kind of important semi-conducting material.Zinc oxide（ZnO）It is kind of a quasiconductor
The electronic structure of catalyst, under having illumination condition, when the photon with certain energy or have and exceed quasiconductor bandgap energy
Photon enter quasiconductor be that electrons transit to conduction band from valence band, thus forming a hole.It is in the conduction band electricity of excited state
Son and valence band hole can tie and offset the energy of input again, and the hole of valence band can be the hydroxyl of surrounding（OH-）Electronics is robbed
Dispossess, so that hydroxyl（OH-）Become free radical, because it has strong oxidizing property, Organic substance can be degraded, by pathogenic bacteria
Kill with virus.But because it has some intrinsic defects, limit its utilization in reality.Zinc oxide is a kind of wide taboo
Band quasiconductor, can only absorb ultraviolet light, and UV energy only accounts for the 4% of solar energy, zinc oxide is for the utilization of sunlight
Rate is very low；Meanwhile, the ultraviolet excitation semiconductor product third contact of a total solar or lunar eclipse gives birth to electron-hole pair, light induced electron and hole be attached to zinc oxide
On organic pollution have an effect, be degraded to water and carbon dioxide, but the recombination rate in light induced electron and hole be remote
More than the speed having an effect with Organic substance, so greatly reduce zinc oxide photocatalysis performance.
