Abstract
The present invention discloses a kind of micropore nano composite material, which is characterized by that said composite material comprises nano material and porous material. The interior of said composite material has lots of micropore channels, communicated to the exterior, so that it can possess full adsorption and catalytic activity, can be used for adsorbing and catalytically-degrading organic material being in liquid pollutant or adsorbing and degrading harmful substances being in gas.
Description
The present invention relates to a kind of composite, relate in particular to a kind of microporous nano composite material.
In the modern society, along with a large amount of uses of chemical building material, internal combustion engine etc., and industrial fast development, it is also serious day by day that harmful substance is polluted the harm that is brought in the air.Simultaneously, because a large amount of generations of sanitary wastewater and industrial wastewater have also brought serious environmental problem.
Because nano particle has quantum size effect, small-size effect, skin effect are utilized the surperficial adsorption capacity of nano material and catalysis characteristics is eliminated pernicious gas or liquid has become the good choice of technology.After nano material particle and other material are made the composite of a fixed structure, just can have the ability of good adsorption and degradation of organic substances matter.
Existing elimination pernicious gas or liquid processes have following two kinds:
(1) mode that adopts porous mass to adsorb.
(2) adopt catalyst to carry out catalytic oxidation.
For (1) method because porous mass easily reaches capacity and inactivation after a certain amount of harmful substance in absorption, therefore bring service life short, return awkward problem into handling trouble, use cost height.For (2) method, adopting nano material (mainly referring to ultramicron) is a kind of preferred scheme, because the efficient of the general catalyst of nano particle catalysis specific activity is high doubly a lot.But problem is, existing nano material self or when being compounded to form fine and close thing material with other material, the absorption of nano particle and catalytic action generally concentrate on material surface and finish, most of nano particle can not be brought into play corresponding effects, thereby form very big waste, or do not reach the effect of anticipation.
For overcoming the shortcoming of above-mentioned technology, the purpose of this invention is to provide a kind of new composite.This composite is by combining the adsorption effect of porous material and the catalytic action of nano material effectively, thereby avoids the inactivation of porous mass, and simultaneously, the catalytic capability of nano material is also fully played.
The present invention is achieved by the following technical programs:
At first, microporous nano composite material of the present invention, it is characterized in that containing nano material and mushy material in this composite, composite inner has the micro channel of a large amount of communicating surface, and nano particle is distributed in the hole of mushy material, surface and on every side.
Wherein, described nano material, be metal nano powder, any one of compound nano powder or its combination, described mushy material can be a kind of of activated carbon, porous silicate or combination, and the ratio of nano material and mushy material weight be 1: 1-1: 40, the average-size of nano particle is preferably 1-100nm between 0.1-500nm.Because only so, can guarantee just that nano particle can distribute equably to come, absorption, catalytic activity are found full expression.
The present invention also provides preparation to have the method for the microporous nano composite material of above-mentioned feature, mainly contains following steps:
(1A) nano particle is compound to the surperficial or inner of mushy material, adds bonding agent again and be made into mixture; Or
(1B) nano particle, mushy material and bonding agent directly are made into mixture;
(2) said mixture is shaped to definite shape by physics or chemical method.
(3) molded material drying becomes the nano composite material with micro channel.
Wherein, described nano material, for any one or they in metal nano powder, the compound nano powder combination; Described mushy material can be any of activated carbon, porous silicate or their combination; Described binding agent can be an inorganic colloid, organic macromolecule is any or their combination.Nano material is 1: 1～1: 40 with the ratio of mushy material weight.The average grain diameter size of nano material is preferably between the 1-100nm between 0.1-500nm.(1A) described method can be preferably vapour deposition or liquid phase coprecipitation simultaneously, and the method for (2) described physics or chemistry is preferably cast or spraying etc.
Purposes of the present invention, be to can be used for to adsorb with catalytic degradation gas in harmful substance, also can be used for adsorbing with the catalytic degradation liquid pollutant in organic substance.Wherein said liquid can be preferably the waste water that contains organic or inorganic impurity.Particularly, can be used for waste water treatment engineering, air-conditioning gas cleaning plant and air cleaner, waste gas purification treatment facility, be preferably used in harmful substance removing in the gas, promptly be used for air-conditioning gas purification, air cleaner, waste gas purification treatment facility.
Compare with other nano-material modified material, the existence of micro channel in the mushy material of the present invention can make the harmful substance in gas or the liquid effectively be adsorbed by whole composite.Be evenly distributed in the hole of mushy material, surface or nano particle on every side then constantly oxidation, decomposing harmful substances, making the present invention eliminate the effect of harmful substance in gas or the liquid can be permanently effective and efficiently keep.
