Abstract

The present invention relates to a full-Si molecular sieve, wherein the full-Si molecular sieve has a Q4/Q3 of (10-90):1 wherein Q4 is the peak strength at the chemical shift of −112±2 ppm in the 29Si NMR spectrum of the full-Si molecular sieve, expressed as the peak height relative to the base line; and Q3 is the peak strength at the chemical shift of −103±2 ppm in the 29Si NMR spectrum of the full-Si molecular sieve, expressed as the peak height relative to the base line.
