La2O2CO3 was prepared by calcination of La2 (CO3)3 in the air.Catalysts Ni-Fe/La2O2CO3 with different mole ratios of Ni to Fe,Ni/La2O2CO3 and Fe/La2O2CO3 were prepared by impregnation method.The catalytic properties were evaluated on steam reforming of ethanol (SRE) from 300 to 700 ℃ under atmospheric pressure and the samples were characterized by Brunauer-Emmett-Teller method (BET),X-ray diffraction (XRD) and temperature programmed reduction (TPR).The results showed that Ni-Fe bimetallic catalysts exhibited higher activities than single metallic catalysts,which was attributed to the co-existence of well dispersed Ni,Fe and LaFeyNi1 yO3.It was found that the catalyst Ni-Fe/La2O2CO3 containing 10 wt.％ Ni and 3 wt.％-5 wt.％ Fe showed the best performance,the conversion of ethanol was 100％,the selectivity of H2 was higher than 90％,and the selectivity of CO was lower than 1.5％ at 400 ℃.
