Dry reforming of methane (DRM) to syngas is a promising way for methane conversion to chemicals, fuels and reduction of greenhouse gas (e.g., CO2 and CH4) emission. Nickel based systems have exhibited relatively high catalytic activity in DRM comparable to noble metal catalysts. However, Ni is prone to rapid deactivation due to coking and sintering under DRM conditions. Application of different active metal addition methods is a possible way to influence activity and stability of catalysts through tuning the strength of interaction between metal and support. In addition to preparation method, metal loading also influences particle size and dispersion. This work elucidates the effect of nickel content and preparation method on the catalytic properties of Ni/CeO2-SnO2 in DRM.
