The presence of a Fe-FeAl2 O4 structure over an Fe-Al2 O3 catalysts is demonstrated to be vital for the catalytic methane decomposition (CMD) activity. After H2 reduction at 750 °C, Fe-Al2 O3 prepared by means of a fusion method, containing 86.5 wt % FeAl2 O4 and 13.5 wt % Fe(0) , showed a stable CMD activity at 750 °C for as long as 10 h.
结果表明，在Fe-Al2O3催化剂上存在Fe-FeAl2O4结构对于催化甲烷分解（CMD）活性至关重要。通过熔融法制备的Fe-Al2O3在750 °C下用H2还原后，含有86.5 wt%的FeAl2O4和13.5 wt%的Fe(0)，在750 °C下显示出长达10 h的稳定CMD活性。
