摘要
采用导向剂法合成了β沸石。XRD光谱测定表明,导向剂的成活以及β沸石的形成被局限于相对较窄的相区范围内。β沸石的29Si和27Al-NMR 光谱表征进一步说明β沸石骨架硅铝四面体的排列较为规整,其中Na+ 离子起着平衡沸石骨架负电荷的作用。
zeolites were synthesized with nucleation gel.It was found that the formations of active nucleation gel and β zeolite were limited in relatively narrow regions determined by XRD. 29 Si and 27 Al\|NMR spectra of β zeolite indicate that the tetrahedrons of Si and Al in the framework are in high order.In addition,the negative charges of the framework may be balanced by sodium cations.
