摘　　要：This work describes a novel method to synthesize NaY zeolite at high temperature(100-140 ℃)by using NaY seeds solution as a silica source,which is also a method for the activation of silica source in the synthesis of NaY zeolite.Conventionally,the synthesis temperature of NaY zeolite from water glass is about 100 ℃,and higher temperature(>100 ℃)leads to the formation of impurity.However,this work shows that high-temperature synthesis(100-140 ℃)still exhibits a pure phase NaY.It is very interesting that,compared with conventional temperature,high-temperature in the synthesis of NaY zeolite has obvious advantages such as short crystallization time and high n(Si)/n(Al)ratio in the product.More importantly,this method is possible to extend to the synthesis of NaA,NaX,Ω,ECR-1and MOR.This work describes a novel method to synthesize NaY zeolite at high temperature（100-140 ℃） by using NaY seeds solution as a silica source, which is also a method for the activation of silica source in the synthesis of NaY zeolite. Conventionally, the synthesis temperature of NaY zeolite from water glass is about 100 ℃, and higher temperature（ 〉 100 ℃ ） leads to the formation of impurity. However, this work shows that high-temperature synthesis（100-140 ℃ ） still exhibits a pure phase NaY. It is very interesting that, compared with conventional temperature, high-temperature in the synthesis of NaY zeolite has obvious advantages such as short crystallization time and high n（Si）/n（Al） ratio in the product. More importantly, this method is possible to extend to the synthesis of NaA, NaX, Ω, ECR-1 and MOR.
