本文简要介绍了自制的几种疏水催化剂的主要特性，采用这些催化剂进行了室温下的Ｈ－Ｔ同位素交换实验，初步考察了氢气流速对催化活性的影响。实验表明，催化剂的催化活性较高，能够用于室温下从氚水中回收氚 In this paper, the main properties of several self-made hydrophobic catalysts were briefly introduced. H-T isotope exchange experiments were carried out at room temperature using these catalysts. The effect of hydrogen flow rate on the catalytic activity was investigated. Experiments show that the catalyst has high catalytic activity and can be used to recover tritium from tritiated water at room temperature
