摘要: Ethanol steam reforming (ESR) is regarded as one of the most potential ways to produce hydrogen. Among the catalysts investigated by far, CeO2-based noble metals exhibited effective performance of ESR due to the unique redox property of CeO2 and the strong metal-support interaction. However, these catalysts usually deactivated quickly when operated at high temperatures and under high space velocities because of the sintering of metals and carbon deposition. So in the current work, a PrOx-doped Ir/Ce0.9Pr0.1O2 catalyst was prepared and the catalytic performance for ESR was examined.This result clearly demonstrated that the incorporation of PrOx into the lattice of ceria substantially promoted the stability of the Ir/Ce0.9Pr0.1O2 catalyst at high temperature and under high space velocity. The enhanced performance might be related with the improved redox property and the enhanced OSC, which could effectively remove the carbon deposition during ESR.
