Description
Technical field
The present invention relates to the manufacturing methods of nano-colloid particulate load object and the nano-colloid particle obtained by the preparation method to bear
Loading.
Background technique
By nano-colloid particle for example as fuel cell, waste gas purification catalyst in use, carried out by ceramics,
The method that the substrates such as macromolecule are impregnated in metal nano colloidal solution and adsorb it.At this point, the specific surface of nano-colloid particle
The bigger catalytic action of product also more improves, it is therefore desirable to the high concentration of the nano-colloid particle in colloidal solution.However, another
Aspect when by particle high concentration, is easy to produce the coarsening as caused by particle mutual aggregation, it is also necessary to inhibit the aggregation.
In order to meet these opposite requirements, carried out following technology: one intramolecular of addition has hydrophobic group and hydrophilic
Dispersing agent, the protective agent of base, make it be adsorbed in the surface of nano-colloid particle, include particle, thus inhibit nano-colloid particle
Mutual aggregation improves dispersibility, obtains the nano-colloid particle dispersion (for example, patent document 1) of high concentration.
However, so by with dispersing agent include nano-colloid particle when, there are the catalysis that nano-colloid particle is expected
The problem of effect etc. is interfered by dispersing agent.
In addition, being described in patent document 2: utilizing reducing agent, so that golden particle is attached to the ethylene such as polyvinyl chloride base system high
The surface of molecule and obtain high molecular material.In turn, it is disclosed in patent document 3: using cellulose to be born in the fiber of principal component
Solid catalyst obtained by the catalyst containing platinum family element is carried, is described, which can for example obtain as follows: make
Above-mentioned fiber is impregnated in the solution containing catalyst, then makes it dry to obtain.However, these 2,3 institutes of patent document
In the method stated, there are problems that being difficult to obtain the loaded article of high concentration.
In addition, being disclosed in patent document 4: having the compound of metal nanoparticle in cellulose nano-fibrous area load
Body.It as its preparation method, describes, makes metallic compound and surface that there is cellulose nano-fibrous this of carboxyl or carboxylate
A little groups combine, and reducing agent etc. is then added, thus by it is above-mentioned with carboxyl etc. in conjunction with metallic compound restore and form metal
Nano particle.However, the nano-colloid particulate load object is thick in the presence of the nano-colloid particle loaded when preparing in higher concentrations
The problem of uncontrollable partial sizes such as bigization.
In turn, disclose in patent document 5: load has the deodorization paper of metal silver colloid in microfibrillated cellulose, records
, by the presence of cationic surfactant and composite metal hydride (reducing agent) by water-soluble silver compound
It restores and obtains.However, including metal colloid particles using the surfactant largely used, therefore can not answer in this method
For other fields such as catalyst.
