摘要: SrCeO 3-δ and SrCe 1-x Eu x O have been reported as promising materials for hydrogen separation membranes. However, their stability needs to be improved under hydrocarbon gas conditions. We report the effect of Zr doping in on chemical stability. CO 2 is main species cause problem, decomposition occurs by following reaction: 3 + ↔ SrCO CeO . By using doping, we subsequently demonstrated that permeation through a tubular 0.7 0.2 0.1 membrane stable water shift reaction
