 1588.    ---------------.  [IVANOV, K. N.]  [X-Ray Examination of Copper Methyl Alcohol Catalysts.]  Mem. Inst. Chem. All-Ukrain. Acad. Sci., vol. 1, 1934, pp. 49-55 (in German, pp. 56-57); Chem. Abs., vol. 29, 1935, p. 6179.

       Activation of CO and H₂ molecules by Cu-ZnO-Cr₂O₃ catalysts (I) is due to active Cu and CuO molecules, the dispersion of which is increased by the ZnO.  Cr₂O₂ acts as a promoter forming solid solutions with CO.  Inactivation of (I) is due to diminution in the dispersion of Cu, to reduction of active CuO, and to increase in the parameters of the Cu lattice consequent on conversion into a-brass.
