Description
Technical field
The present invention relates to the mesoporous silicon-dioxide-substrate field of compound material, particularly a kind of is the nickel-base catalyst and preparation method thereof and application of carrier with yttrium (Y) doping SBA-15.
Background technology
Mesoporous material has that high specific surface area, structural arrangement are regular in order, pore size homogeneous, surface, duct can carry out remarkable advantages such as physical absorption or chemical modification.Use the nanostructured self-assembling technique to synthesize mesoporous SiO first from Kresge in 1992
2(MCM-41) since, the preparation of mesoporous material, performance and application are the domestic and international research focuses always, its catalysis, absorption, separation, senser element, nano material are synthetic, large biological molecule is immobilized and field such as medicament slow release in shown advantageous characteristic, caused the extensive concern of international physics, chemistry and material educational circles.
Chinese scholars utilizes different template agent to synthesize the molecular sieve of many types, and SBA-15 is a kind of representative molecular sieve (Zhao D.Y.et al.Science1998; 279:548).It has bigger specific area, and the channel diameter of homogeneous distributes, but the aperture of modulation, and wall thickness and hydrothermal stability height are so SBA-15 has wide practical use in fields such as catalysis, separation, biology and nano materials.From atomic level, the skeleton of the silicon-based mesoporous material of broad research mainly is by amorphous Si O at present
2Form, lack the activated centre, the application aspect catalysis is subjected to very big restriction.Therefore, in the hole wall of mesoporous material or duct, introduce specific catalytic active center (as: metal ion or rare earth element) by some synthesis strategies, namely mesoporous material is carried out chemical modification, be intended to improve its catalytic performance.
In the building-up process of introducing metal ion or rare earth element, adopt hydro-thermal method (Zhu Y.et al.J.Mater.Chem.2011 usually; 21:11457), this is geologist's simulating nature circle mineralization and a kind of synthetic method of beginning one's study in the middle of the 19th century.Scientists has been set up the hydro-thermal blending theory and has been begun the research of functional material subsequently.Prepared over one hundred kind of crystal with hydro-thermal method at present.The category of hydro-thermal liquid chemical method owned by France refers to be solvent with water, the chemical reaction that carries out under the condition of HTHP in the pressure vessel of sealing.Hydro-thermal method need be filtered and washing operation usually, can make the metal that embeds in the molecular sieve when filtering loss be arranged like this, thereby can not guarantee that both quantitative metal embeds (Li J et al.J Mater Sci2008 in the molecular sieve effectively; 43:6359).On the other hand, the SBA-15 molecular sieve is synthetic in strongly acidic solution, certainly will cause the pre-metal ion of introducing to be difficult to success and enter in the skeleton of molecular sieve, therefore can cause the embedded quantity of metal ion lower; In addition, hydro-thermal method need be under 100-110 ° of C just can guarantee to synthesize the crystal with perfect crystal formation in hydro-thermal reaction 2-4 days in autoclave, therefore not only time-consuming, and reactor, temperature etc. is had high requirement.
