Hydrogen chloride oxidation reaction catalyst for preparing chlorine, and preparation method therefor

Abstract

The present invention relates to a catalyst for obtaining chlorine (Cl2) through an oxidation reaction of hydrogen chloride (HCl), and more particularly, to an oxidation reaction catalyst for preparing Cl2 from HCl by addition of a second heterogeneous material to a RuO2-supported catalyst using TiO2 as a support, and a preparation method therefor. According to an embodiment of the present invention, a hydrogen chloride oxidation reaction catalyst for use in a method for preparing chlorine by oxidizing hydrogen chloride includes a support and a heterogeneous material in an active ingredient. The catalyst according to the present invention has both increased catalytic activity at a low temperature and enhanced thermal stability, and thus a catalyst having improved durability such as thermal stability at a high temperature is provided. Therefore, since thermal stability is secured, the performance of the catalyst is maintained for a long time even at a high temperature.
