| Research Abstract |
Thermal efficiency of the hydrogen production by the thermochemical water-splitting iodine-sulfur process will be improved by increasing the hydrogen iodide concentration in the hydriodic acid obtained by the Bunsen reaction using an ionic liquid. It was experimentally confirmed that the solubility of iodine and sulfur dioxide in the ionic liquids are higher than that in hydrogen iodide and water, respectively. The hydrogen iodide concentration in the hydriodic acid obtained by the Bunsen reaction using the ionic liquid was higher than that in the conventional Bunsen reaction.
