![عکس صفحه اول مقاله: Support influence on Ni–Cu catalysts behavior under ethanol oxidative reforming reaction Support influence on Ni–Cu catalysts behavior under ethanol oxidative reforming reaction](/preview/png/1278905.png)
The ethanol oxidative reforming reaction was performed with Ni–Cu catalysts on different supports. The results indicated that Ni–Cu/Nb2O5 and Ni–Cu/ZnO were the most appropriate catalysts for the reaction regarding activity, stability, and selectivity for hydrogen production. Ni–Cu/Nb2O5 catalysts have strong acidity (at 600 °C), while ZnO has very low acidity. Ni–Cu/Ce0.6Zr0.4O2 catalysts, which only have weak acidity (at 250 °C), presented poor stability and hydrogen selectivity. This shows that acidity has no influence on hydrogen production.
► Ni–Cu catalysts.
► Support influence for ethanol oxidative reforming reaction.
► Acidity influence on hydrogen production.
► Reaction is not favored for catalysts whose support has a large quantity of oxygen atoms on the surface.
► The semiconductivity of ZnO and Nb2O5 supports improves hydrogen production.
