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