Abstract

A series of catalysts based on mesoporous ceria solid solutions containing NiCo active component was synthesized via co- precipitation, impregnation, hydrothermal and core–shell (sol–gel) methods and applied to partial oxidation and dry reforming of methane. In the co-precipitated and impregnated catalysts, a better NiCo dispersion and a stronger interaction between NiCo species and the ceria- based support in comparison with other catalysts were observed, which affected activity and selectivity. Thus, simpler methods of applying the active component were more advantageous owing to the manifestation of strong metal–support interactions.

用于甲烷干重整和部分氧化的 NiCo-Gd0.1Ti0.1Zr0.1Ce0.7O2 催化剂:NiCo 应用方法对甲烷转化为合成气的影响
通过共沉淀、浸渍、水热和核壳(溶胶-凝胶)等方法合成了一系列含有镍钴活性组分的介孔铈固溶体催化剂,并将其应用于甲烷的部分氧化和干重整。与其他催化剂相比,共沉淀和浸渍催化剂中的镍钴分散性更好,镍钴物种与铈基载体之间的相互作用更强,从而影响了催化剂的活性和选择性。因此,由于金属与载体之间存在强烈的相互作用,应用活性组分的简单方法更具优势。

期刊介绍: Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
