Abstract
The invention discloses an air purification material doped by zinc oxide, which belongs to the technical field of functional materials. The air purification material comprises, by weight, 50 to 90 parts of ethyl titanate, 2 to 10 parts of nanometer zinc oxide, 20 to 40 parts of chitin nanofiber, 3 to 10 parts of polyethylene glycol, 200 to 500 parts of absolute ethyl alcohol and 10 to 50 parts of water. According to the invention, through uniform doping of TiO2, the phenomenon of agglomeration of TiO2 with the passage of time due to high surface energy is prevented, and long-term stable photocatalytic activity is maintained; through usage of polyethylene glycol, uniform fine micropores are formed in the compact surface of TiO2, and surface agglomeration of TiO2 is overcome to some extent; and through adsorption by chitin nanofiber, the concentration of pollutants on the material is increased, so a basis is provided for smooth photocatalysis of TiO2.
Description
Technical field
The invention belongs to technical field of function materials, relate to a kind of cleanser, relate in particular to a kind of sky of doping zinc-oxideGas scavenging material and preparation method thereof.
Background technology
In recent years, along with the fast development of China's urban industry, atmosphere pollution is day by day serious, and air quality is further dislikedChange, not only jeopardize people's normal life, and people's physical and mental health is worked the mischief. With closely bound up indoor of peopleAir quality also makes people worried, and particularly this year, various materials discharged along with the extensive use of architectural decorative and fitting materialsA large amount of harmful substance (as: volatile organic contaminant such as formaldehyde, toluene, benzene) severe contaminations indoor air environment, and thenTo the healthy of the mankind and operating efficiency important. How to remove efficiently as effumabilities such as formaldehyde, toluene, benzeneOrganic compound becomes the focus that researcher pays close attention to, and utilizes the functional material of some modifications to select as catalyst or adsorbentProperty ground carries out harmless treatment to volatile organic compound becomes the most effective approach.
The removal method of volatile organic compound mainly contains active carbon adsorption, the woody plant method of purification, static and removesThe method such as dirt, photocatalysis, wherein, people are for TiO2Photocatalysis carried out a large amount of research, becomes current photocatalysis fieldResearch emphasis and focus. TiO2Photochemical catalyst, the organic matter that its degradable is a large amount of, as benzene,toluene,xylene, naphthalene, halo virtueHydrocarbon, formaldehyde, NOx, ammonia, hydrogen sulfide, tetrachloro-ethylene, carbon monoxide etc. TiO2Photocatalytic mechanism be in the time of illumination, its valence bandOn an electronics (e-) will be excited, when crossing forbidden band while entering conduction band, in valence band, produce corresponding hole (h+)。And this photohole has very strong oxidability (its standard hydrogen electrode current potential is at 1.0-3.5V), thereby at TiO2On surface, formRedox system, this redox system almost can be oxidized all Organic Pollutants, and they are completely oxidized to CO2And H2O, and can not produce secondary pollution.
But TiO2Also there are some shortcomings in photocatalysis, this is because in light catalytic purifying field, and pollutant levels conventionallyLow, and TiO2Itself there is no adsorption capacity, therefore needs extra carrier that pollutant is adsorbed onto to surface upper, thereby by TiO2UrgeChange and decompose. In addition, due to TiO2There is high surface energy and be highly susceptible to occurring surface reunion, thereby as time goes by, the utmost pointThe earth has reduced its photocatalytic activity. In order to overcome these defects, people have researched and developed multiple supported titanium2Material for air purification,Such as active carbon, silica gel, Woelm Alumina, NACF etc. carry out load. But up to now, for using chitin nanometerFiber-loaded TiO2Material for air purification, had not yet to see report. Meanwhile, for the new supported titanium of exploitation2Air cleaning materialMaterial still has eager demand and requirement, is also one of research topic of air purification field.
