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.

通过热化学水裂解碘-硫方法制氢的热效率将通过增加使用离子液体通过本生反应获得的碘酸中的碘化氢浓度来提高。实验证实碘和二氧化硫在离子液体中的溶解度分别高于在碘化氢和水中的溶解度。通过使用离子液体的本生反应得到的碘酸中的碘化氢浓度高于常规本生反应。
