Abstract
AbstractDifferent promoters have a significant impact on the catalyst performance. In this paper, the effects of different promoters on the physical properties and catalytic behavior of methane dry reforming catalysts were investigated. A series of characterizations showed that the Mg, Ba, and Ca promoters increased the basicity of the catalysts. However, their high concentration of OH− leads to the destruction of Ni3Si2O5(OH)4 species, which results in a decrease of catalytic performance. The addition of Ce significantly improves the catalyst stability. After 100 h of Ni‐5Ce‐MSC reaction, there was almost no carbon deposition, exhibiting high activity and resistance to carbon accumulation. These findings provide a new perspective for the design of nickel‐based dry reforming catalysts.
