We have developed a hydrophobic catalyst for the combustion of hydrogen for the purpose to prevent a nuclear facility from hydrogen explosion in its severe accident. The iodine-resistance of the catalyst was investigated. The Pt-Pd catalysts were prepared especially with an inorganic carrier which is chemically treated to be hydrophobic. The hydrogen combustion tests were carried out in the presence of iodine in air. Tritium was mixed in air to improve the analytical accuracy of reaction by radioactivity counting. The Pt-Pd catalyst manufactured by noble acetylacetonate technique lost its catalytic activity in the presence of iodine in air. The Pt-Pd catalyst manufactured by the newly proposed technique with noble chloride salt maintained its catalytic activity in the presence of not only iodine but methyl iodide and chlorine gas. The developed catalyst will be a promising catalyst for nuclear facility due to its iodine-resistance and capability for hydrogen combustion at room temperature
