Abstract

Chlorination of methane was carried out over the Pt/NaY zeolite catalysts having different dispersion and location. On the finely dispersed platinum particles inside the zeolite methylchloride was the sole product, while on the large platinum ones outside surface of the zeolite all four chloromethanes were produced. Besides the role of highly dispersed platinum particles, the confined volume of the supercages in the support seems to have played another role on the exclusive production of methylchloride by restricting the further chlorination.
