Ethanol and ethanol-water mixture were converted directly into H2 with ～60% selectivity and ～100% conversion by a catalytic reforming on nickle lanthanide oxide catalysts. The catalysts were optimized and the refroming reaction were performed at temperatures sufficiently low that the water gas shift(WGS) reaction can be combined to decrease CO .This process has great potential for low-cost H2 generation in fuel cells for small portable applications while where liquid fuel storage is essential and where systems must be small, simple, and robust.%在镧系金属氧化物载镍催化剂上通过催化重整乙醇和乙醇水溶液可以直接转化为H2,H2的选择性达到60%,乙醇的转化率达到100%.优化催化剂及降低重整反应的温度以使水汽转化反应同时发生来降低产物气中CO的含量.该过程对于生产小型燃料电池的低成本燃料H2,以及便携燃料电池系统需要液态燃料存储的应用具有巨大的潜在价值.
