Technical field
The invention belongs to precious metal catalyzing organic to synthesize field, is specifically related to one kind and is carried on nano platinum particle
In metal-organic framework materials (MOFs), a kind of new Pt@MIL-101 composites are formed, the material can be very good to be catalyzed
Aromatic alcohol is oxidized to aromatic aldehyde, enriches application of the metal platinum in catalytic aerobic oxidation reaction.
Background technology
The selective aerobic oxidation of alcohols into aldehyde be a kind of important catalytic reaction.Aldehyde is in the industrial production using very
Extensive organic compound, and aromatic aldehyde is even more the intermediate of many synthetic drugs, chemical materials, therefore probe into aromatic alcohol Gao Xuan
The catalytic reaction for the being oxidized to aromatic aldehyde tool of selecting property is of great significance.In many cases, homogeneous catalyst has good
Good catalytic effect, but in industrialized production, there is the problem of certain, it is such as more difficult to the burn into of reaction utensil
Post processing, the limitation recycled etc., therefore its application is limited to a certain extent.Solid catalyst has reaction condition
The advantages that gentle and preferable catalytic activity, while also repeat and utilize and be easily isolated, therefore application prospect is more wide.
Nano platinum particle is a kind of good different-phase catalyst, has the active and higher ratio surface of preferable atomic surface
Product.Nano platinum particle is set to load on these carriers such as dilute graphite, alundum (Al2O3), silica, activated carbon in recent years, though one
Determine the catalytic activity that degree improves catalyst, but these carriers are difficult the work for playing guard catalyst in catalytic reaction process
With, the loss of active metal is easily caused, metal nanoparticle is reunited, and catalyst activity is weakened or even is inactivated.
The content of the invention
The present invention is that after simple equivalent impregnation, reducing process directly will from the chloroplatinic acid of platinum compounds containing metal
Together with nano platinum particle is effectively combined with metal-organic framework materials, a kind of composite wood new with pore space structure is formed
Material-Pt@MIL-101.And the composite can be catalyzed the aerobic oxidation reaction of aromatic alcohol, only react 12 hours and just reach
81% conversion ratio, selectively reaches 99%.Present metal platinum has extensively using value in catalytic field.

Above-mentioned Pt@MIL-101 composites, in step (1), described highly basic is potassium hydroxide or sodium hydroxide.It is excellent
Choosing, highly basic is sodium hydroxide.The purpose of selection highly basic is to make alkali and chloroplatinic acid in molar ratio 2:1 reacts.When in chlorine platinum
When quantitative potassium hydroxide is directly added into sour methanol solution, due to potassium chloroplatinate, solubility is smaller in methanol solution, and there have to be heavy
Form sediment and generate, when the potassium chloroplatinate solution of certain volume is so taken in follow-up loading process, and the amount of platinum can not be determined；When adding
Enter sodium hydroxide and do not produce precipitation, form the methanol solution of platinic sodium chloride, therefore selected highly basic sodium hydroxide to neutralize
The acidity of chloroplatinic acid.
Above-mentioned Pt@MIL-101 composites, in step (3), described reducing agent is sodium borohydride.Reduction temperature is

The carrier of agent.MOFs is a kind of a kind of caused new material by metal cation and the mutual self assembly of organic ligand,
MOFs is again because it has the characteristics that stratiform and pore space structure, and be otherwise known as Porous coordination polymer and coordination network polymers.
Most of this solid material all possesses good pore space structure and larger specific surface area, exactly because there are both special
Property, MOFs materials are set in the property and Qi Ke that gas stores and separation, field of heterogeneous catalysis extensive use, while MOFs are stable
The three-dimensional structure of meter, become a kind of useful catalyst carrier.The metal-organic framework materials MIL-101 that the present invention uses is carried
Body has pore space structure, it is possible to nano platinum particle is immobilized on well in MIL-101 hole, avoids nano platinum particle
Generation is reunited and influences catalytic effect.
2. due to the unstability that MIL-101 materials are shown in acid condition, therefore it is difficult direct by infusion process
Chloroplatinic acid is supported in MIL-101 materials, and the present invention attempts the acidity for selecting appropriate alkali to be used for neutralizing chloroplatinic acid, so as to
Reach and chloroplatinic acid is directly supported on the purpose in MIL-101 materials.
3. the present invention is directly from the chloroplatinic acid of platinum compounds containing metal, after equivalent impregnation, reducing process is made new
Pt@MIL-101 composites, raw material is easy to get, and method is simple.
