Abstract
The major stumbling block of thermal dissociation of H2O has been the requirement of a high dissociation temperature which causes problems both with materials for the reactor and with energy conversion efficiency for the process. For example, only about 0.7 % of H2O can be dissociated at 2000 K in equilibrium state and at least 2500 K is required for a feasible dissociation. Thus, it has been very difficult to develop a viable H2 production process with the thermal dissociation of H2O. In this study, we show that the dissociation temperature can be drastically lowered when H2O is thermally dissociated on solid acid materials. A possible mechanism of the thermal dissociation of H2O on solid acid materials is also proposed, based on some experimental results.
