Abstract

Bifunctional oxidative and acidic catalyst was prepared by incorporation of titanium ion (Ti4+) and niobic acid in zeolite molecular-sieve. Nb/TS-1 was prepared by hydrothermal synthesis of Titanium silicalite, TS-1, calcination in air and subsequent impregnation of niobium (3-20 wt% Nb2O5) into TS-1. Acidity of the sample was characterized by pyridine adsorption technique. Pyridine adsorption study shows both Brønsted and Lewis acid sites are present in all Nb/TS-1 samples.
