WitrynaThe solar-driven splitting of hydrohalic acids (HX) is an important and fast growing research direction for H 2 production. In addition to the hydrogen, the resulting chemicals (X 2 /X 3 - ) can be used to propagate a continuous process in a closed cycle and are themselves useful products. Here we present a strategy for photocatalytic hydrogen … HI is a colorless gas that reacts with oxygen to give water and iodine. With moist air, HI gives a mist (or fumes) of hydroiodic acid. It is exceptionally soluble in water, giving hydroiodic acid. One liter of water will dissolve 425 liters of HI gas, the most concentrated solution having only four water molecules per molecule of HI.
