Manage technical field.
Background technology
Traditional method for treating water efficiency is low, cost is high, there are secondary pollution problems, and waste water control always cannot be well
Solution.The development and application of nanometer technology are likely to thoroughly solve this problem.Start within 1972 to find TiO2Oxidation activity
Higher, chemical stability is good, harmless to the human body, and cost is low, pollution-free, has a wide range of application, thus is most paid attention to, but TiO2
Larger (such as anatase TiO of energy gap2Energy gap Eg=3.2eV), be only capable of absorb ultraviolet region (wavelength is less than
Light 387nm), the utilization ratio to solar energy is relatively low.
In contaminant degradation and production of energy field, conductor photocatalysis is one of most promising method.Work as energy
Amount will produce point of electron-hole pair when being more than or equal to the photon irradiation of semiconductor energy gap in photocatalyst surface
From this is the initial basic step of light-catalyzed reaction.In order to find efficient photochemical catalyst, numerous studies work is all concentrated on
In the influence factor for studying photocatalytic activity.In June, 2010, material research institution researcher has found that silver orthophosphate has light
The effect of catalyst, and photooxidation effect is to be currently known more than the decades of times of various photochemical catalysts.But due to silver orthophosphate itself
Unstable, easy self-reversal, causes catalyst degradation performance to reduce rapidly in photocatalysis.And it is that a nothing is stopped to improve photocatalysis effect
The work in border.Further, since nano particle is difficult to be separated from waste water after processing waste water, it is therefore desirable to which nano particle is loaded
On some carriers.The material synthesized on its surface is a kind of composite, can there is good photocatalysis effect.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to propose a kind of silver-colored photochemical catalyst of the silver-colored compound phosphoric acid of wolframic acid
Preparation method, this method is that catalyst and carrier are combined closely in carrier surface formation catalyst.
The technical solution adopted by the present invention is to use following steps：
1) 12~16mmol silver nitrates are weighed, 18mmol/L silver nitrate solution is configured to, 6.6~8mmol wolframic acids are weighed
Sodium, is configured to 18mmol/L sodium tungstate solution；
2) both the above solution is mixed under 350~400 revs/min of rotating speed, forms colloid substance, persistently stir 3
~4h, sodium tungstate and nitric acid silver reaction in whipping process generate wolframic acid silver colloid；
3) wolframic acid silver colloid is placed in pellicle bag, with water washing is distilled 3~4 times, gets rid of dissociated ion, then should
Wolframic acid silver colloid is added in the sodium radio-phosphate,P-32 solution that 60~80mL concentration is 3~4mol/L, is soaked 2~4 days, in wolframic acid Argent grain
Surface forms phosphoric acid silver nano-grain, and one kind is made in separation of solid and liquid, deionized water washing solid 2~3 times, 75~105 DEG C of drying
The silver-colored photochemical catalyst of wolframic acid silver compound phosphoric acid.
The beneficial effects of the invention are as follows：(1) this method utilizes the difference of solubility product constant, in wolframic acid silver surface formation solubility
The smaller phosphoric acid Argent grain of product constant.
(2) wolframic acid silver and silver orthophosphate are combined, synergy, and wolframic acid silver can be made preferably to play catalysis under visible light and made
With and good catalytic effect can be obtained.
