“…T. Fukunaga et al. found that Cu−Mn spinel oxide prepared by calcining the precursor at 900 °C produced smaller copper particle and higher activity in MSR than non‐spinel Cu−Mn oxide synthesized at 300 °C . Besides, Cu−Al spinel catalysts exhibit the highest catalytic activity in MSR than other copper based spinel, such as Cu−Fe, Cu−Cr, Cu−Mn, Cu−La .…”

Copper metal catalysts suffer from gradual loss of activity due to the agglomeration and sintering of active metals during the catalytic reaction processes. Herein, we show that enhanced catalytic durability for methanol steam reforming (MSR) can be achieved by using Ni modified Cu−Al spinel solid solution as catalysts without pre‐reduction treatment. In so doing, Cu atoms can be gradually released from spinel structure after the initiating of reaction by non‐spinel CuO entities. Incorporation of Ni in the spinel structure reveals two positive effects: slowing down the Cu releasing rate and producing even smaller Cu nanoparticles as compared to that of Cu−Al spinel. Since Ni2+ ions in spinel framework cannot be reduced during the catalytic process, we suggest that the remaining defective CuaNib□cAldO4 spinel structure plays a crucial role in stabilizing the formed Cu nanoparticles. The synthesized sample with 0.05 mol Ni per mol Cu shows the best catalytic performance as demonstrated by pretty stable activity during the long‐term catalytic testing up to 2000 h. The findings show great commercial application potentials for the production of H2 from MSR.

“…Low temperature steam reforming mainly focuses on Cu-based [3][4][5][6][7][8][9][10][11][12][13][14][15] and Pd-based [16][17][18][19][20][21][22] catalysts. For Cu-based catalysts, the most extensively studied catalysts are Cu/ZnO and Cu/ZnO/Al 2 O 3 [7,9,10], etc.…”

“…Especially, copper oxides have been widely examined as combustion catalysts in various forms such as bulk metal oxides or supported metal oxides [5][6][7][8][9][10][11][12][13][14]. Wang et al [8] proposed that the CuO/c-Al 2 O 3 is the best combination between the metal species (Cu, Fe, Mn, Cr, Co, Mo or Ni) and the supports (CeO 2 , c-Al 2 O 3 , TiO 2 or V 2 O 5 ) for toluene oxidation.…”
