A group of iron-doped novel oxides of cerium, terbium, and praseodymium are reported to produce hydrogen at relatively low temperatures through a cycling two-step reaction process without catalyst. Iron doping in the oxides not only stimulates surface activity, but also lowers the reduction temperature of water vapor (to ∼ 375 °C) while preserving efficient hydrogen production. The two-step reactions eliminate the problem of catalyst deactivation due to coke. Thus the cycle can be carried out continuously without replacing oxide.
