以甲胺水溶液为改性剂,高硅Y型沸石可在常温下吸附甲胺(MA)制备有机-无机杂化酸碱双功能高硅Y型沸石材料.X射线粉末衍射(XRD),固体29Si魔角核磁共振(13C及29SiMAS NMR)表征表明甲胺分子与高硅Y型沸石骨架相互作用导致沸石结构发生变化,骨架上生成新的Si—N键及Si—OH.以热重分析(TG/DTG),NH3,CO2程序升温脱附(NH3-TPD和CO2-TPD)研究杂化Y型沸石的酸碱性质及其经不同温度焙烧后的变化,结果表明,杂化后沸石的酸/碱量,尤其是后者明显增大,其原因是骨架上生成了新的Si—OH及Si—N键. Using methylamine aqueous solution as modifier, high-Y zeolite can be used to prepare organic-inorganic hybrid acid-base bifunctional high-silicon Y zeolite by adsorbing methylamine (MA) at room temperature.X-ray powder diffraction (XRD), solid Characterization by 29Si magic angle nuclear magnetic resonance (13C and 29SiMAS NMR) showed that the interaction between methylamine and the high-silica Y-type zeolite resulted in the change of zeolite structure and the formation of new Si-N bonds and Si-OH on the framework. TG / DTG), NH3, CO2 temperature-programmed desorption (NH3-TPD and CO2-TPD) were used to study the acid-base properties of hybrid Y zeolites and their changes after calcination at different temperatures. / Base amount, especially the latter is significantly increased, the reason is the skeleton formed a new Si-OH and Si-N bond.
