A Comparative Synthesis of Ni-Cu Oxides over Al۲O۳-ZrO۲ Nanocomposite via Impregnation and Sol-Gel Methods Used for CH۴/CO۲ Reforming

In dry reforming of methane, Ni/Al۲O۳ catalyst suffers from less activity and stability, due to the side reactions [۱, ۲]. Addition of zirconia and Cu as promoters to Ni/Al۲O۳ has increased stability and activity, respectively [۱-۳]. Zirconia decreased coking and sintering of active phases [۲]. In this research, the properties of Ni/Al۲O۳ catalyst were improved by utilization of sol-gel method and ZrO۲ and Cu addition as suitable promoters.
