摘要

Keggin-type 12-tungstophosphoric acid (TPA) nanocrystals have been assembled inside the pores of mesoporous silica through a vacuum impregnation method by using largepore SBA-15 as a nanoreactor. The product was characterized by Brunauer-Emmet-Teller particle size distri bution (BET-PSD), NMR and FT-IR spectroscopy, X-ray diffraction (XRD), tranmsission electron microscopy (TEM), differential thermal analysis (DTA) and FT-IR of adsorbed pyridine. The experimental results illustrale that the TPA nanocrystals are excellent Brønsted acid catalytic materials at room temperature.
