Abstract
A SCM-33 molecular sieve has a schematic chemical composition as shown in the formula 'SiO·1/x XO·m MO', wherein X is a framework trivalent element, the Si/X molar ratio x is ≥5, M is a framework equilibrium cation, and the M/Si molar ratio is 0<m≤1. The molecular sieve is a novel molecular sieve with RTE topology and the molecular sieve requires short preparation time, involves a low synthesis cost and can be used as adsorbent or catalyst.
