Abstract

The development of efficient catalysts with high activities and durabilities for use in the dry reforming of methane (DRM) is desirable but challenging. We report the development of a nanoporous nickel composite (nanoporous Ni/YO) via a facile one-step dealloying technique, for use in the DRM. Focusing on the low-temperature DRM, our composite possessed remarkable activity and durability against coking compared with conventional particle-based Ni catalysts. This was attributed to the aluminum oxides present on the Ni surface, which suppress pore coarsening. In addition, the inert bundled YO nanowires are suitable for use as substrates for nanoporous Ni.

摘要

开发用于甲烷干重整（DRM）的具有高活性和耐久性的高效催化剂是理想的，但具有挑战性。我们报告了通过一种简便的一步脱合金技术开发的一种纳米多孔镍复合材料（纳米多孔Ni/YO），用于DRM。针对低温DRM，与传统的基于颗粒的镍催化剂相比，我们的复合材料具有显著的活性和抗结焦耐久性。这归因于镍表面存在的氧化铝，它抑制了孔的粗化。此外，惰性的束状YO纳米线适合用作纳米多孔镍的基底。
