In order to decontaminate waste tritium gas

Pt or Pd catalysts on inorganic carrier were prepared by wet impregnation.At environmental temperature

the catalysts exhibit good effect in the catalysis reaction of tritium gas oxidation

with an efficiency of tritium gas oxidation of over 90%

being well suitable for tritium waster gas processing.Physicochemical properties and structure of the catalysts were examined by XRD.The results showed that carrier revision enhanced the crystallization degree of carriers

this will improve the hydrophobic property of carriers

and the revision of carriers reduced the crystal size of Pt

enhance the dispersion of Pt.The method of deoxidize after ablation and Pt loading reduced the dispersion degree of Pt.ZrO2 reduced the crystal size of Pd

enhanced the dispersion of Pd.
