Supported nickel catalysts are promising candidates for dry reforming of methane, but agglomeration of Ni⁰ and coke deposition hinder the industrial applications. Herein, we report a novel interface-directed synthetic approach to construct distinct metal ensembles by carefully tuning the compositions of the carriers. A Zr-Mn-Zn ternary oxide-supported Ni catalyst, together with the respective binary oxide-supported analogues, was synthesized by adopting a sequential co-precipitation and wetness impregnation method. Combined characterization techniques identify distinct catalyst models, including (i) conventional NiO nanoparticles with different sizes on Zr-Mn and Zr-Zn, and (ii) epitaxially growing NiO ensembles of a few nanometers thickness at the periphery of MnZnO_x particles. These catalysts exhibit divergent responses in the catalytic testing, with the ternary oxide system significantly outperforming the binary analogues. The strong electronic interactions between Mn-Ni increase Ni dispersion and the activity while the stability is strengthened upon Zn addition. Both high activity, high selectivity, and remarkable stability are attained upon co-adding Mn and Zn. The interfaces between Ni and Zr-Mn-Zn rather than the physical contacts of individual oxide-supported analogues through mechanical mixing are keys for the outstanding performance.

负载型镍催化剂是甲烷干重整的有希望的候选者，但 Ni ^{0 的}团聚和焦炭沉积阻碍了工业应用。在此，我们报告了一种新颖的界面导向合成方法，通过仔细调整载体的成分来构建不同的金属集合。采用顺序共沉淀和湿浸渍法合成了 Zr-Mn-Zn 三元氧化物负载的 Ni 催化剂以及相应的二元氧化物负载类似物。组合表征技术确定了不同的催化剂模型，包括 (i) 在 Zr-Mn 和 Zr-Zn 上具有不同尺寸的常规 NiO 纳米粒子，以及 (ii) 在 MnZnO _x外围外延生长几纳米厚度的 NiO 系综粒子。这些催化剂在催化测试中表现出不同的反应，三元氧化物系统明显优于二元类似物。Mn-Ni 之间的强电子相互作用增加了 Ni 的分散性和活性，同时加入 Zn 后稳定性得到加强。Mn 和 Zn 的共添加可同时获得高活性、高选择性和显着的稳定性。Ni 和 Zr-Mn-Zn 之间的界面，而不是通过机械混合的单个氧化物负载类似物的物理接触，是实现出色性能的关键。
