Description
Technical field
The invention belongs to Environmental Chemistry technical fields, and in particular to a kind of ultraviolet optical drive nano silver/wolframic acid silver is compound is urged
Agent, preparation method and its application in environmental area.
Background technology
The moment such as water pollution, air pollution in life are all threatening people's health.How pollution, protection ring are reduced
Border becomes the problem of countries in the world are paid close attention to jointly.Therefore, how efficient process harmful organic substance becomes the heat that environmental area is studied
Point.At present most study, the use of most wide photochemical catalyst is anatase titanium dioxide nano-powder, it is cheap because its is safe and non-toxic
Price and photocatalysis performance outstanding and by numerous concerns.Anatase titanium dioxide is disadvantageous in that, energy gap
It is wider, the ultraviolet excitation (λ with specific wavelength is needed when in use<387nm), and the energy of ultraviolet region is less than too in sunlight
The 5% of sunlight gross energy, if using the direct catalytic degradation organic pollution of sunlight, the effect is unsatisfactory.In order to solve this
One problem, it is seen that photochemical catalyst becomes the hot spot of photocatalysis field research.Although wolframic acid silver photochemical catalyst is that one kind is had excellent performance
Visible light catalyst, but seldom about wolframic acid silver photochemical catalyst report at present, the catalytic effect of the Ag tungstate catalyst of acquisition
Need to further increase, hinder such material field of environmental improvement practical application process.
It is well known that the specific surface area for improving catalyst is the most common means for promoting catalyst effect, and this
Invention is directed to the existing dissatisfactory deficiency of Ag tungstate catalyst catalytic effect, creatively proposes a kind of nano silver/wolframic acid
The preparation method of silver-colored composite catalyst generates the side of nano silver and micro-injection reactant by using wolframic acid silver photodecomposition
Method has prepared nano silver/wolframic acid silver composite photo-catalyst.The ingenious plasma resonance that nano silver particles are utilized of this method
Effect significantly improves degradation efficiency of the wolframic acid silver photochemical catalyst to organic pollution.
Invention content
It is an object of the invention to propose a kind of preparation side of new ultra-violet optical drive nano silver/wolframic acid silver composite catalyst
Method, acquisition catalytic performance is superior, the novel nano photochemical catalyst of stable structure, solves existing pure titinium dioxide or load dioxy
The visible light utilization efficiency of Ag tungstate catalyst that the catalyst visible light catalytic effect of change titanium is undesirable and common is low, is catalyzed
The problems such as journey is slow, while the usage amount of wolframic acid silver when degradation unit volume is catalyzed object is effectively reduced, improve catalyst
Service efficiency reduces the use cost of catalyst, help to realize Ag tungstate catalyst field of environmental improvement quantum jump.
The present invention proposes a kind of preparation method of ultraviolet optical drive nano silver/wolframic acid silver composite catalyst, specific to prepare
Step is:1) silver nitrate solution and ammonium hydroxide is used to prepare silver ammino solution;2) prepared sodium tungstate solution is put into beaker, is added

Enter into sodium tungstate solution;4) precipitation of generation is centrifuged, it is dry after washing, then be placed under ultraviolet light and irradiate 1~3 point
Clock generates Nano silver grain in wolframic acid silver surface, collects product, obtain nano silver/wolframic acid silver composite catalyst.
The specific preparation condition of nano silver/wolframic acid silver composite catalyst is in the present invention:1) the addition matter of surfactant
Amount:The 0.5~10% of silver-colored source and sodium tungstate quality summation;2) template used in is polyethylene glycols or triton x-100
Or one kind of Tween 80 or Sodium Polyacrylate or neopelex.3) light source used in is ultraviolet light.
The invention has the advantages that:
1, it has been put forward for the first time a kind of method preparing nano silver/wolframic acid silver composite photo-catalyst using light sensitivity principles.
2. since the nano silver prepared by this method has plasma resonance effect, urging for wolframic acid silver can be obviously improved
Change activity.Compared with single wolframic acid silver photochemical catalyst, nano silver/wolframic acid silver composite photo-catalyst is in the same amount of Luo Dan that degrades
When bright B, catalytic efficiency is 10 times of existing Ag tungstate catalyst or more.
3. the present invention prepares nano silver/wolframic acid silver composite photocatalyst under the conditions of ultraviolet light by micro-injection for the first time
Agent, and new pattern can be generated by changing the type of surfactant, to realize for different-shape nano silver/wolframic acid
The compound controlledly synthesis of silver.It is compared compared with method, not only product catalyst performance is good, but also realizes that the artificial of morphology and size can
Control, meets different application demands.
