| Sumario: | This work shows the preparation and physicochemical and electrochemical characterization of Pt based catalysts supported on two different catalyst supports (Vulcan carbon and SiC/TiC) with a 40 wt% Pt content for the depolarized SO2 electro-oxidation in the hybrid sulfur process, which is a promising approach for the hydrogen production. The Pt based catalysts supported on carbon showed the lowest Pt crystallite size, but the electrochemical surface area of the Pt deposited on the Si0.9CTi0.1C was the highest of the three catalysts prepared in the lab under the same operation conditions. The Pt catalysts supported on the novel SiC/TiC based material are promising catalysts for this technology as they showed high catalyst activity and durability in sulfuric acid conditions. |
