A catalyst for COS hydrolysis includes titanium dioxide and a barium compound supported on the titanium dioxide. The catalyst, when expressing Ba and S in the catalyst in terms of BaO and SO3, respectively, has a molar ratio of SO3 to BaO of at least 1. The catalyst converts COS and H2O in a raw material gas to CO2 and H2S.
