Methane dry reforming: influence of the SiO2 and Al2O3 supports on the catalytic properties of Ni catalysts

The effect of the support nature (SiO₂, Al₂O₃, SiO₂–Al₂O₃) on the catalytic performance of Ni-based catalysts prepared by the incipient wetness method was explored in the dry reforming of methane reaction, and the catalysts were characterized by TG-DTA, SEM-EDX, XRD and UV-VIS methods. The results demonstrate that NiO supported on SiO₂-modified Al₂O₃ exhibits superior catalytic performance in methane dry reforming in the temperature range of 650–700 °C.
