ABSTRACT:
Hydrogen iodide is efficiently decomposed to hydrogen and iodine by treatment in the liquid phase with a platinum group metal catalyst. At temperatures between about 0.degree. C. and about 150.degree. C. and pressures sufficiently high to maintain the liquid phase, at least about 50 percent of the hydrogen iodide present can be decomposed at a reasonable rate of reaction. The hydrogen which is created is easily separated as a gas. Exemplary catalysts include platinum particles and supported catalysts, such as ruthenium on a titania substrate and platinum on a barium sulfate substrate.
