Novel Ni–Re super-alloy nanowire type catalyst system is found for hydrogen generation from steam methane reforming. The novel nanowire type catalysts exhibit the super-high catalytic activity for hydrogen generation from steam methane reforming with CO-free in the product at lower reaction temperatures. The Ni–Re alloy nanowire type catalysts are active for converting methane and water to hydrogen and carbon dioxide at a low reaction temperature of about 623 K, which is about 200 K lower than that is needed for steam methane reforming on the conventional catalysts. The CO-free hydrogen is efficiently generated from steam methane reforming on the nanowire type catalysts at the lower reaction temperatures, in which water–gas shift reaction step is not needed for CO-free hydrogen production.

用于蒸汽甲烷重整无CO制氢的新型高活性Ni-Re高温合金纳米线催化剂

发现新型 Ni-Re 超合金纳米线型催化剂体系可用于蒸汽甲烷重整制氢。新型纳米线型催化剂在较低反应温度下对蒸汽甲烷重整制氢表现出超高催化活性，产物中不含 CO。Ni-Re 合金纳米线型催化剂在约 623 K 的低反应温度下具有将甲烷和水转化为氢气和二氧化碳的活性，这比传统催化剂上蒸汽甲烷重整所需的温度低约 200 K。在较低的反应温度下，通过纳米线型催化剂上的蒸汽甲烷重整有效地产生不含 CO 的氢气，其中水煤气变换反应步骤不需要用于不含 CO 的氢气生产。
