Energy crisis, the environmental problem come are also increasingly serious.Green Development is persistently recycled in order to realize, the control of environmental pollution and is controlled
Reason has become a urgent problem to be solved.Wherein, the improvement of organic pollution belongs to the emphasis of pollution control again.Thus, chemistry
The exploitation of pollutant innoxious process for treating is the key that environmental protection.
It has been be proved that, the semiconductor of nanostructured is with photocatalyst come degradable organic pollutant and in toxic chemical
There are huge potentiality in terms of the removal of substance.But semiconductor apply to photochemical catalyst there are the problem of it is also obvious that surface
Reaction efficiency is low, and spectral response range is narrow, and quantum efficiency is low etc., therefore semiconductor is difficult to direct extensive utilization.
Have in terms of the hard-degraded substance that photocatalysis oxidation technique can not be handled in conventional methods such as processing biochemistry, materializations wide
Wealthy application prospect.Under the current energy and environmental problem background urgently to be resolved hurrily, utilization and the Nano semiconductor of sunlight
With reference to one of research hotspot for having become people.So far, a large amount of semi-conducting material such as metal oxide and sulfide
(such as：TiO2, WO3, CdS, ZnS, ZnO) and effective photochemical catalyst is all identified as, with degradable organic pollutant.
Wherein ZnO is a kind of up-and-coming photochemical catalyst, and active height, chemical stability is good, nontoxic, availability
By force, the advantages that at low cost.However, the ZnO photo-generated carriers probability of recombination is high, it is serious to visible light-responded deficiency, optical defect etc.
Affect its application in photocatalysis field.Therefore many methods such as ion doping, noble-metal-supported and with other semiconductors
Compound be used to prepare together ZnO photocatalyst to enhance separation of charge, improve to visible absorption.Recently, ZnO and conjugation
The compound effective way for having proved to be raising photocatalytic activity, expanding light abstraction width of π structural materials.
At present, g-C3N4Electron hole pair is generated all as light absorber, nano-ZnO is wide band gap semiconducter material with Zn0
Material has photocatalysis characteristic, photoelectric conversion characteristic, nontoxic and non-migratory and the characteristic properties such as surface-active and sensitivity characteristic.
Graphite-like carbonitride (g-C3N4) a kind of pi-conjugated material is used as, it is shown under visible light illumination to production hydrogen and organic degradation
Good photocatalytic activity.And g-C3N4It is a kind of polymer of softness, can be easily compounded in the surface of other compounds
On, thus the compound of the two has obtained extensive concern and quickly development.
The appearance structure of ZnO has significant effect the transformation efficiency of light anode, and wherein three-dimensional manometer spherical structure is compared with one, two
The electricity conversion for tieing up structure is high.There is researcher to synthesize photochemical catalyst g-C both at home and abroad3N4/ ZnO, the results showed that, light is urged
The photocatalysis performance of agent is better than single C3N4Or ZnO.But in the prior art, it has been found that in ZnO and g-C3N4It is multiple
In the preparation for closing object, the pattern of ZnO cannot be adjusted well, and wherein most is graininess or petal-shaped.And the absorption of ZnO
Spectrum hinders its application and development prospect in ultraviolet region and its higher electron-hole recombination rate.
Therefore, design synthesis is a kind of inhibits electron-hole to answer with high light absorption range and effectively again with high absorption property
The catalysis material of the performances such as conjunction efficiently uses one of the problem of solar energy is as urgent need to resolve.
