PREPARATION OF PLATINUM GROUP METAL ON POROUS SUBSTRATE ELECTRODE

摘要

Process for preparing electrodes for the oxidation of sulfur dioxide (including the oxidation of sulfur dioxide in a sulfur cycle process for hydrogen generation) in which a platinum group metal containing catalyst material is coated evenly onto a high-surface-area porous substrate. A solution is applied onto the substrate by a vacuum filtration method. A pressure differential of at least 10 mm-Hg is applied across the substrate. The substrate is uniformly heated (preferably by radiant heating).
