The present invention relates to a monolith catalyst for carbon-dioxide/methane reforming and a method of manufacturing the same, and more particularly to a novel monolith catalyst for a reforming reaction having improved thermal durability, configured such that a sintering inhibiting layer is formed by coating the surface of a monolith support with at least one element selected from the group consisting of Group 2, 3, 6, 13, 15 and 16 elements among elements in Period 3 or higher and an active catalyst layer is formed on the sintering inhibiting layer, thereby preventing carbon deposition and catalyst deactivation due to deterioration even upon reaction at high temperatures.

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 SO.sub.3, respectively, has a molar ratio of SO.sub.3 to BaO of at least 1. The catalyst converts COS and H.sub.2O in a raw material gas to CO.sub.2 and H.sub.2S.
