The present invention relates to a kind of fabric/poly- nitrogen/polypyrrole/titanium dioxide catalysis material preparation methods.This method comprises: fabric/poly- nitrogen material preparation, fabric/poly- nitrogen/polypyrrole/titanium dioxide catalysis material preparation.This method effectively widens photoresponse region to near-infrared, the utilization rate of solar energy is substantially improved, catalysis material can be repeated several times recycling.
Description
Technical field
The invention belongs to composite photocatalyst material field, in particular to a kind of fabric/poly- nitrogen/polypyrrole/titanium dioxide is urged
Change the preparation method of material.
Background technique
With the quickening of China's industrialization and urbanization process, by organic pollutant, Polymer wastes, biomass pollution and
Caused environmental pollution has become a serious social concern.Even if the organic dirt of certain low concentrations may also generate high poison
Property, to constitute a serious threat to the ecosystem and human health.Traditional pollutant process technology, such as physical absorption, chemistry
The methods of precipitating cannot completely remove these organic dirts, and may generate many other nocuousness in the actual operation process
By-product causes secondary pollution.Therefore, it is necessary to a kind of effective " green " technologies by noxious pollutant be converted into innocuous substance and
It not will cause secondary pollution.In order to solve these problems, a lot of research work person attempts to solve the problems, such as this with scientific method, with
Realize the sustainable development of human society.In recent years, Photocatalitic Technique of Semiconductor is unanimously considered to solve environmental problem
Effectively, the solution of green and most prospect.This technology has huge economic and social benefit in field of environmental improvement,
It is even more especially to yield unusually brilliant results in the fields such as sewage treatment, air cleaning and antibacterial of keeping a public place clean.However, current most of photochemical catalysts
Be primarily present following problems: (primarily responsive to ultraviolet light) too low to solar energy utilization ratio, quantum efficiency be low and recycling difficulty etc..
Therefore, the catalysis material designing and developing a kind of efficient catalytic and easily recycling is of great significance.
The common photochemical catalyst such as titanium dioxide, zinc oxide, tungstic acid, band gap is generally wider, and anti-light corrosivity is preferable,
But its response region is mainly at ultra-violet (UV) band (account for solar energy 5% or so).Therefore, the photoresponse model of photochemical catalyst is widened
It encloses, improves the utilization rate to sunlight, be the important research direction of current photocatalysis technology.Currently used method has noble metal
Doping, semiconductors coupling and ion doping etc..Studies have shown that these methods successfully optical response range can be extended to it is visible
Light area, but wavelength can be widened successfully to rarely having near infrared region to and heard of (visible light account for solar energy 45%).
It in order to effectively load to catalysis material on fabric, and does not influence its catalytic efficiency as far as possible, there is researcher
Once by the way of padding by photocatalyst to fabric, research shows that loaded using this method, binding strength compared with
It is good, but it only also is covered on fiber surface since catalyst is most of, the catalyst into fibrous inside is less and keeps its water-fast
It is poor to wash fastness；And cause fabric corrosion more serious since the pick-up of padding method is higher.Also there is researcher using colloidal sol-
The method of gel loads to catalyst on fabric, the advantage is that simple process and can effectively improve fabric self-cleaning effect
(by controlling surface roughness), but generally carry out load using the method and high temperature is needed to bake, fabric can be caused so directly
Damage, also results in catalyst agglomeration, influences photocatalysis effect.Simultaneously as catalyst forms chemical bond in conjunction with fabric
Active force is faint, repeatedly easily falls off after washing, substantially reduces its photocatalysis efficiency.Compare patent
CN201611095874.5, CN201611095891.9, the catalyst that these patents use all are under visible light, to light source benefit
With rate, and it is weaker with the active force of fiber, its repeat performance is influenced, secondary pollution is caused, seriously constrains technology
Industrial applications, this patent overcomes existing patent insufficient, using high performance catalyst under near infrared light, and passes through covalent bond side
Formula and fiber combine, and durability is good, and repeat performance is good.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of fabric/poly- nitrogen/polypyrrole/titanium dioxide catalysis materials
