Preparation of alveolate hydrophobic catalyst for tritium waste gas treatment

The alveolate hydrophobic catalyst was essentially waterproof and not easily poisoned by moisture. At room temperature, the conversion of 1% H2 in humid air over the catalyst was higher than 95% at 0-16000 h−1 and 0-100% relative humidities. The reaction rate constant of the oxidation of tritium in humid room air over alveolate hydrophobic catalyst at room temperature is much higher than normal honeycomb catalyst.
