The research results show for low Sn concentrations, for example 1wt%Sn with respect to Ni, the Ni/Sn surface alloy is energetically preferred. We have also used XPS to characterize the catalysts. The quantified Sn and Ni XP spectra for Ni/Sn/SLT catalysts show that Sn preferentially segregates to the surface of the Ni/Sn alloy. We demonstrate that supported Ni/Sn alloy catalyst provides significantly higher reforming reactivity and resistance to deactivation via carbon deposition than supported monometallic Ni catalyst both in steam reforming of CH4 and CO_2 dry reforming.

本文以SLT为支撑体，利用Sn对传统的Ni基催化剂进行表面合金化处理，成功制备了Ni/Sn表面合金重整催化剂，将该催化剂用于甲烷和丙烷的CO_2重整和水蒸汽重整反应，研究结果表明，在Sn浓度很低的情况下，例如1wt%Sn含量，从能量角度看更易于形成表面合金，XPS数据也显示Sn更易于富集在Ni/Sn合金催化剂表面。
