EFFECTIVE SUPPORTED-In2O3 FOR THE PRODUCTION OF HYDROGEN FROM WATER BY THE REDUCTION-OXIDATION CYCLE OF In2O3

Eleven kinds of carriers for In2O3 have been tested for the production of hydrogen from water by a reduction and oxidation cycle of In2O3. Of these, the most effective carriers were TiO2, ZrO2, active carbon and ZnO, because the high enhancing effects on the rates of reduction and oxidation and the high final yields of hydrogen by the reduced In2O3 have been observed by using these carriers.
