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.
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.
