Description
Technical field
The present invention relates to a kind for the treatment of process of photocatalytic degradation of dye waste water, the unordered nano-encapsulated type adulterated using Fe
TiO2Photochemical catalyst, the special structure of the photochemical catalyst and Fe elements are in TiO2Doping between lattice has been obviously improved TiO2Light is urged
The visible light catalysis activity of agent, the treatment process have the advantages that easy to operate, of low cost, degradation efficiency is high.
Background technology
In textile printing and dyeing process, largely use pollution environment and harmful auxiliary agent, these auxiliary agents big
Discharged more in the form of liquid, inevitably into water body environment, cause water pollution.If rhdamine B is with carcinogenic
And mutagenicity, the chroma in waste water containing rhodamine B is deep, organic pollution content is high, biological degradability is poor, with conventional method
Such as physisorphtion, Fenton process are difficult to administer, and cause to pollute water quality long-term degradation, seriously endanger the strong of water body environment and the mankind
Health, therefore seem particularly significant and urgent to the degradation treatment of this kind of waste water.
But how to use clean energy resource high efficiency, low cost, it is still one and huge challenge and there is far-reaching meaning
Justice.So there is an urgent need to develop new energy such as solar energy, wind energy, tide energy, biological energy source, the hydrogen using environmentally friendly and high energy storage by people
Energy, ocean energy etc., can cost-effectively substitute fossil and mineral resources, real on the premise of environmental protection and human health
Effectively converting and not influencing people for the existing energy is normally lived.A large amount of Novel environment-friendlymaterial materials are come into being in recent years.Nanometer
TiO2Material be exactly it is this can environment purification and efficiently utilize solar energy green functional material.It not only has oxidability
By force, excellent chemical stability, energy expenditure, without follow-up secondary pollution the advantages that, but also there is cheap, nontoxic nothing
Evil, can long-time service the features such as, therefore enjoy the favor and concern of photocatalysis researcher in recent years, and it extensively should
For the quick magnificent solar cell of new energy field such as dyestuff, photodissociation aquatic products hydrogen, microwave absorption, light absorption, biological medicine processing, light
Lie prostrate battery, photocatalysis, lithium ion battery etc..
But semiconductor TiO2Material there is also some it is serious the defects of, such as pure TiO2The photo-generate electron-hole of photochemical catalyst
To short life, light abstraction width is narrow low with light conversion efficiency, limits the application of solid powder th-1 catalyst.So need to receiving
The pattern of rice titanium dioxide is modified and study on the modification, and it is extremely urgent to sun efficiency of light absorption to improve it.Therefore, close
Reason ground prepares Hydrogen Energy with solar energy and conductor oxidate and effectively Environment control will be subject to people more and more to pay attention to.
From solar-energy photo-voltaic cell under the conditions of Japanese Scientists Fujishima and Honda discovery ultraviolet light in 1972
TiO2During electrode there occurs the interesting fact of photocatalytic water since, since nearly half a century, researchers are put into largely
Energy research TiO2Modification, illustrate analyze its catalytic mechanism, with deepening continuously for research, light-catalyzed reaction mechanism is further
It is clear, on TiO2The fast rapid-result focus of research, and also achieve different degrees of progress in all fields, but from
The theoretical research stage in laboratory is still on the whole, also has very big distance apart from industrial applications, in order to effectively improve
TiO2The catalytic activity of catalyst, currently used method include that narrow gap semiconductor is compound therewith, metal and nonmetal ion
Doping, noble metal loading, surface photosensitizer the methods of come change catalytic inner crystalline structure and outside surface group
Into and property reduce catalyst band gap distance, improve catalyst to the absorbability of visible ray reach enhancing TiO2Photocatalytic
The purpose of energy.
In recent years, Mao etc. employs a kind of breakthrough method for hydrogenation and is prepared for a unordered nano-TiO2, thus method
The TiO being prepared into2Energy gap there was only 1.54eV, possess very outstanding visible absorption performance and photolysis water hydrogen
Performance, but modification is doped to it, and use it for the organic pollution in photocatalyst for degrading water body and relevant degraded
Then there has been no systematic research for technique.
