Description
Technical field
The present invention relates to the preparation method and application that a kind of porous rare earth organic coordination compound is catalyst based, be specifically related to a kind of Ce-MOFAgTiO
2the preparation method of catalyst and the organic application of catalytic reduction thereof, belong to the technical fields such as material science, nano material, metal organic complex, chemical industry, catalysis.
Background technology
Metal-organic complex is based on different metal ions and all kinds of rigidity or flexible organic ligand, the base polymer formed by ligand complex effect.Inorganic chemistry and organic chemistry not only integrate by this complex, and the subjects such as inorganic chemistry, crystal chemistry and materials chemistry are connected closely, potential application in catalysis, molecular recognition, photoelectricity, magnetic, Subjective and Objective exchange and molecular conductor, has become one of focus of new material research exploitation.
When Metal-organic complex is formed, except participating in except coordination by metal and organic ligand, also comprise the non-covalent interactions such as hydrogen bond, pi-pi accumulation effect and electrostatic interaction.Therefore, traditional unimolecule complex, due to the periodicity repetitive that the effect of the non-covalent bond such as hydrogen bond and pi-pi accumulation is formed, can not have the frame structure of three dimensions expansion, is referred to as superstructure or supermolecule to space three-dimensional expansion or other.Traditional unimolecule complex and multidimensional complex, be referred to as metal-organic supermolecular or metal-organic framework (Metal-OrganicFramework), referred to as MOF.Compared with other porous material, this material specific surface area is large, porosity is high, structure and potential characteristic relation close, in many-sides such as catalysis, absorption, separation, film, sensing, identification, proton conduction, medicament slow releases, show the multifunctionality that other conventional porous materials can not be compared.
The preparation of MOF mainly contains diffusion method and solvent-thermal method.Diffusion method refers to that reactant solution generates a kind of method of target product by processes such as liquid level contact, diffusion, reactions.The method reaction condition is gentleer, application comparatively early, but its deficiency to be preparation manipulation loaded down with trivial details, reaction time is long, is difficult to the controlledly synthesis realizing crystal, and the crystal grown is irregular.Solvent-thermal method be apply the most generally, method the most practical.Specific practice be by slaine, organic ligand and water or other solvent seal in the stainless steel cauldron of inner liner polytetrafluoroethylene, when being heated to uniform temperature (80-300 DEG C), in still, pressure can reach a hundreds of atmospheric pressure, cause chemical compound lot solubilizing reaction in the supercritical state, after maintaining a period of time, slow cooling, reactant mixture obtains the crystal of sizeable systematicness by reactive crystallization.In the synthesis of MOF crystalline material, the crystal of this kind of method synthesis has that crystal structure is good, shape is regular, device therefor is simple, operate the advantages such as easy.But its limitation is that preparation time is also longer, and needs HTHP step, the application in the industrial production of this method is hindered to the challenge etc. of production equipment and high energy consumption.
Nano metal is the metal material that a class particle diameter is less than 100nm, for bulk metal material, due to the design feature of the uniquenesses such as its particle size is little, specific area is large, show and upgrade and more excellent characteristic, become indispensable catalyst in catalysis technical field.For improving the catalytic activity of Nano Silver, its preparation for the purpose of the particle obtaining single dispersing, controlled shape, but because of its specific surface energy large, very easily reunite in synthesis and catalytic process, thus cause its catalytic activity to reduce.Solving one of method of nano metal reunion problem is adopt porous carrier load, porous carrier is conducive to the decentralization improving silver on the one hand, especially the consumption of silver can be reduced, reduce catalyst cost, on the other hand, its synergy can be played, improve catalytic activity, improve stability and the service life of extending catalyst.Research and development MOF load-type nanometer metal, and have the features such as preparation is simple, energy consumption of reaction is low concurrently, must have broad application prospects.
Summary of the invention
