(2) background technology:
In recent years, people are the performance of improving semi-conducting materials such as titanium dioxide, enlarge its photoresponse scope and improve photocatalysis usefulness, and many researchers adopt means such as doping, compound, photoactivate to carry out the research work of titanium dioxide compound both at home and abroad.Reported that people such as Liu Lifen add P-25 type titanium dioxide 0.1 molar concentration liquor argenti nitratis ophthalmicus of stoichiometry volume according to the doping of synthetic sample silver under 300 ℃ temperature for 211 pages to 217 pages of " Chinese Journal of Inorganic Chemistry " second phase in 2008, through ultrasonic dispersion, add sodium borohydride, can prepare silver/titanium dioxide compound.Chinese patent ZL200910185186.1 " a kind of preparation method of silver/titanium dioxide compound " also discloses people such as Xu Zhibing and has adopted Nano Silver and the tetrabutyl titanate method of silver/titanium dioxide compound that has been feedstock production.
Adopting dye sensitization photocatalyst also is one of research hot subject of people.Photosensitizer can be attached to the semiconductor surfaces such as titanium dioxide of high-ratio surface through chemisorbed or physical absorption.Semiconductor also transmits as the notes people that the length of electronics is accepted the photosensitizer excitation electron apart from transmission system, thereby the electron capture agent finally realizes the separation of electron hole at the semiconductor surface trapped electrons.Photosensitizer commonly used comprises inorganic dyestuff, organic dyestuff and high polymer etc.429 pages to 433 pages of " Catalysis Communications " 2007 the 8th phases have been reported conjugated polymer [PFT, Poly (fluorene-co-thiophene)] the sensitization nano-TiO that people such as Song adopt monomer fluorenes and thiophene and are polymerized
2, studies show that the sensitization nano-TiO
2The Pyrogentisinic Acid has photocatalysis performance preferably under visible light.But there are problems such as sensitizer price height, sensitization cost height in this method.
(3) summary of the invention:
The object of the present invention is to provide the preparation method that a kind of cost is low, simple to operate, be fit to the photoactivate silver/titanium dioxide compound of suitability for industrialized production.
For achieving the above object, the preparation method of a kind of photoactivate silver/titanium dioxide compound of the present invention, its steps in sequence is:
One, gets fresh green leaf, clean, remove middle arteries and veins, fast chopping, with it with acetone by mass ratio be: 1: 2-50 fully mixes, and adds solid particle again, and leaf with the mass of solid particles ratio is: 1: 0.1-10, ground at normal temperatures 5-60 minute, and filtered then, get the chlorophyll extract;
Wherein: solid particle is one or both in quartz sand, the calcium carbonate;
Two, in the chlorophyll extract by silver/titanium dioxide compound and leaf mass ratio be: 1: 0.1-50 adds silver/titanium dioxide compound, soaks 0.1-24 hour under the room temperature then;
Three, the suspension after above-mentioned silver/titanium dioxide compound is soaked in the chlorophyll extract at normal temperatures, under the 20-267Pa vacuum dry 6-72 hour, obtain photoactivated silver/titanium dioxide compound.
Owing to taked technique scheme, the present invention relates to the preparation method of described a kind of photoactivate silver/titanium dioxide compound by silver/titanium dioxide compound and chlorophyll extract is abundant, evenly mixing, has prepared the photoactivate silver/titanium dioxide compound after the drying.Overcome problems such as existing photosensitive materials preparation cost height, catalytic performance be undesirable, be expected to be widely used in fields such as chemistry, biology and materials.Can be used for aspects such as sterilization, antifouling, deodorizing, the various organic pollutions of degraded as the photoactivate silver/titanium dioxide compound as a kind of photochemical catalyst; Compare as photochemical catalyst with titania powder and silver/titanium dioxide compound, this kind photoactivate silver/titanium dioxide compound photocatalytic activity obviously improves.
