PREPARATION OF CERIUM-IMPREGNATED SODIUMY AND INVESTIGATION OF ACID-BASE BY CATALYTIC TRANSFORMATION OF METHYLBUTYNOL

Cerium on zeolite NaY was prepared by incipient wetness impregnation (Ce-NaY-IMP). Upon calcination, CeO(2 )species is generated, as confirmed by Raman and DR UV-Vis spectroscopy. The investigation of acid-base properties by the transformation of methylbutynol (MBOH) revealed that Ce-NaY-IMP enhanced only the selectivity of basic pathway products. The impregnation increased Lewis basic sites from oxygen vacancies within CeO2 lattice. In addition, the basicity of Ce-NaY-IMP suppressed the acidity or charge compensating cations sites of parent NaY.
