Abstract: Described are a catalyst, a honeycomb-type catalyst body for decomposing perfluorocompounds (PFCs), and a method of preparing the same. The described catalyst for decomposing PFCs and the method of preparing the same are as follows. Zinc as an active component for performance improvement and tungsten (W) as an auxiliary component are added to alumina selected from at least one of gamma alumina, aluminum trihydroxide, boehmite, and pseudo-boehmite, and a weight ratio of Al, Zn, and W is at 100:30 to 100:1 to 11. The catalyst for decomposing PFCs not only has an effect of having durability against fluorine generated by decomposition of PFCs but also has a synergistic effect of improving reaction activity. Furthermore, the catalyst decomposes PFCs at a lower temperature than conventional catalysts for decomposing PFCs. Thus, it is possible to reduce operating costs and secure the durability of the system during continuous operation.
