Particle diameter≤the 15nm of described photocatalyst agent, wherein the content of nano TiO 2 is greater than 98%.Its form is powdery or liquid, and color is that white is yellow partially, specific area (m
2/ g):＞180, pH value is 6-8, drying loss＜1.0, calcination loss＜2.
The photocatalyst new composite charcoal sorbing material of making at last is granular, and particle diameter is 1mm-10mm.
The preparation method of described photocatalyst new composite charcoal sorbing material is as follows:
Ventilating, under the dustless indoor environment, above component being added in the container by above-mentioned percentage by weight, start the agitator low or first gear to mid ranger operation 30-90 minute, temperature is a room temperature; The particle diameter of pressing 1mm-10mm then squeezes behind the grain again with the baker oven dry, again through 600-1000 ℃ of high-temperature calcination charing, promptly makes photocatalyst new composite charcoal sorbing material.
The working mechanism of the photocatalyst new composite charcoal sorbing material after making is: the micro hole construction that is had a large amount of different apertures by carbo lignius, clay, the haydite photocatalyst new composite charcoal sorbing material that agent is formed with photocatalyst, include the ultra-fine micropore of a lot of molecular levels (20 dust), these micropores can adsorb chemical substance and the gas that produces stink effectively; Because have in the component with Main Ingredients and Appearance is the photocatalyst agent of nano TiO 2, nano TiO 2 is active very strong photochemical catalyst, the photocatalyst agent not only has good absorbability to ultraviolet ray, and visible light also there is higher absorbability, so can utilize a big chunk luminous energy in daylight and the white light, strengthen photo-catalysis capability, under the irradiation of daylight and white light, Electron absorption luminous energy on the nano TiO 2 valence band of photocatalyst agent and be excited on the conduction band and produce the high activity electronics that has very strong negative electricity, on valence band, produce the hole (h+) of positively charged simultaneously, the hole is right one by one thereby produce the electronics with very strong activity, forms redox system.These electronics one holes are to moving to behind the titanium dioxide surface and airborne water (H
2O) have an effect, final hydroxyl free (OH) and the superoxides ion that produce with highly chemical oxidation activity, the electron affinity energy power of OH free radical is strong, attacks the organic molecule position of high cloud density easily, forms the intermediate product of further oxidation and produces the effect of antibiotic sterilization.Since the specific area of photocatalyst agent very big (＞140m2/g), strengthened the adsorption capacity of photocatalyst new composite charcoal sorbing material, for light-catalyzed reaction provides big active surface, produce hydroxyl free (OH) because of photocatalysis and can contact more fully with the air pollutants or the bacterium of photocatalyst new composite charcoal absorption, thereby carry out antibiotic sterilization and deodorizing with the superoxides ion with highly chemical oxidation activity.
The principal character and the purposes of the photocatalyst new composite charcoal sorbing material after making have following six aspects:
1. the micropore of different stage distributes:
The micro hole construction that has a large amount of different apertures by carbo lignius, clay, the haydite photocatalyst new composite charcoal sorbing material that agent is formed with photocatalyst, include the ultra-fine micropore of a lot of molecular levels (20 dust), these micropores can adsorb chemical substance and the gas that produces stink effectively, also have be suitable for the micropore that microorganism live of a lot of 0.01nm to 100nm simultaneously.Therefore photocatalyst new composite charcoal sorbing material of the present invention has the excellent air cleaning and the function of purification of water quality.
2. the absorption of PARA FORMALDEHYDE PRILLS(91,95) gas:
People enter newly-decorated room or when buying the retail sales of clamping plate, tend to feel dazzling, laryngalgia etc., and these symptoms are called the new house syndrome.Formaldehyde is the main cause that causes the new house syndrome.The new house syndrome also is considered to cause reason allergic, that pant.Photocatalyst new composite charcoal sorbing material is removed it because of unique adsorption capacity of its ultra-fine micropore absorbing formaldehyde gas effectively from air.According to experimental determination, photocatalyst new composite charcoal sorbing material of the present invention is than fast 5 times of the speed of commercially available mineral porous adsorbing material absorbing formaldehyde commonly used, and adsorbance wants big 4-5 doubly.
3. to the absorption of ammonia:
Ammonia is one of reason that causes stench.Photocatalyst new composite charcoal sorbing material is removed it because of the effective absorbing ammonia of unique adsorption capacity of its ultra-fine micropore from air.According to experimental determination, photocatalyst new composite charcoal sorbing material can reach 100% to the clearance of ammonia more than 20 hours, and commercially available bamboo charcoal commonly used and binchotan clearance to ammonia after 20 hours have only about 30%.
4. to the absorption of hydrogen sulfide gas:
Identical with ammonia, hydrogen sulfide gas also is one of reason that causes stench (particularly rancid).Photocatalyst new composite charcoal sorbing material has the excellent function of adsorption of hydrogen sulfide gas because of unique adsorption capacity of its ultra-fine micropore.According to experimental determination, photocatalyst new composite charcoal sorbing material is general bamboo charcoal and binchotan 2.5 times to the excellent adsorption capacity of hydrogen sulfide gas.
5. the residual chlorine ion in the removal water:
Photocatalyst new composite charcoal sorbing material can not only be removed the residual chlorine residue in the running water, eliminates the distinctive stink of running water, and the mineral matter that himself can also be contained is soluble in water, so that good to eat drinking water to be provided.According to experimental determination, in the water that contains a constant volume chlorion, in 48 hours, photocatalyst new composite charcoal sorbing material reaches 100% to the clearance of chlorion in the water, and uses the bamboo charcoal clearance of same amount to have only 60%.
6. the ammonia nitrogen in the removal water:
Ammonia nitrogen in the water is harmful to fish.Photocatalyst new composite charcoal sorbing material has the micro hole construction in a large amount of different apertures, and has a ultra-fine micropore of a lot of molecular levels (20 dust), do not having under the situation of strong illumination, these micropores can be fit to microorganism inhabitations such as bacterial digestion, and microorganisms such as bacterial digestion have digestion to the ammonia nitrogen that suppresses the release of spoilage organism and fish faeces, can keep water quality pure and fresh clean.
Implement photocatalyst new composite charcoal sorbing material of the present invention, because it is fired carbonization and forms by charcoal, clay, haydite and photocatalyst agent are compound, has triplen, absorption to polluter changes chemisorbed into by simple physical absorption, decompose while adsorbing, improve absorption contamination particle species, improved adsorption efficiency and saturated capacity; And, can not produce secondary pollution, prolonged the service life of sorbing material greatly.Its adsorption efficiency is 2.5 times of common active carbon, and overcome and used active carbon can produce the shortcoming of powder and black pollution, pollutants such as the chemical pollutant in the environment, biological pollutant, VOC, stink, flue dust are had strong adsorption capacity, are the good functional materials of environment purification.By antibiotic sterilization and deodorization agent of air cleaning or the filtering material that photocatalyst new composite charcoal sorbing material of the present invention is made, can be used for the antibiotic sterilization of filtering material in fields such as indoor reception room such as dwelling house, hotel, hotel, meeting room, Karaoke chamber, automobile, subway, toilet, lavatory, wardrobe, shoe chest, air-conditioning, air purifier or the deodorizing absorption of filtering material.
