Abstract

Provided are a catalyst for hydrolysis and use of a titanium dioxide-based composition which are capable of removing COS and HCN simultaneously at high degradation percentages. The catalyst for hydrolysis is a catalyst for hydrolysis of carbonyl sulfide and hydrogen cyanide, having at least: an active component containing, as a main component, at least one metal selected from the group consisting of barium, nickel, ruthenium, cobalt, and molybdenum; and a titanium dioxide-based support supporting the active component.
