文摘

Ni-Mg-Mn-Fe-O catalysts were prepared via co-precipitation through layered double hydroxide (LDH) precursors and tested for hydrogen production from ethanol by auto-thermal reforming (ATR). With Mn and Fe in the precursor of the Ni_0.35 Mg_2.65Mn_0.5Fe_0.5O_{4.5 卤 未} catalyst, an LDH structure formed via co-precipitation, and after calcination, a cubic MgO skeleton formed with spinel phases of NiMn₂O₄ and NiFe₂O₄. The H₂ yield reached 4.0 mol-H₂/mol-EtOH and remained stable in a 30-h ATR test, which can be attributed to the improvement of reduction behavior and stability of Ni⁰ species.
