Silicate-1 molecular sieve and preparation method thereof

The invention relates to a Silicate-1 molecular sieve, which is characterized in that the Silicate-1 molecular sieve contains metal, the ratio of AHB to AISO is (15-50): 1, and AHB and AISO respectively represent the peak intensity at the wave number of 3400 cm and the peak intensity at the wave number of 3725 cm in an infrared spectrogram of the Silicate-1 molecular sieve, and are represented by peak areas. The molecular sieve has high crystallinity and high hydrogen bond silicon hydroxyl ratio. 一种Silicate-1分子筛，其特征在于，该Silicate-1分子筛含有金属，AHB：AISO为(15-50)：1，AHB和AISO分别代表所述Silicate-1分子筛的红外谱图中波数为3400cm-1处和波数为3725cm-1处的峰强度，以峰面积表示。该分子筛具有高结晶度和高氢键硅羟基占比。
