        Adsorption of H2 on catalysts of MoO2 base is being investigated.  Contrary tot he results of other authors this oxide has not been found to be stable in the presence of H2.  In the temperature range in which Mignolet worked, a slow reduction of the MoO2 was observed, and it is now the aim to find the reduced form stable under conditions suitable for the technical use of MoO2.  The apparatus used in the experiments is described.
