Catalytic Performance of Ni-Co/Al2O3-MgO-ZrO2 Nanocatalyst at Different MgO Contents Using Zirconyl Nitrate Solution Precursor for CO2 Reforming of Methane

The industrial application of dry reforming of methane is limited by coke formation and efficient catalyst design. To this aim, Ni-Co/Al2O3-MgO-ZrO2 nanocatalysts with different loadings ofMgO were prepared by sol-gel method and tested for CO2 reforming of methane. The prepared nanocatalysts were characterized by XRD and FESEM analysis. According to the FESEM images, increasing the MgO content leads to uniform, tuneable and smaller particle size. XRD patternsshow that by increasing the amount of MgO, crystallite size decreases. The catalytic results showed that the synthesized nanocatalysts exhibit high catalytic activity as well as long stability.However, the one with high amount of MgO exhibited better catalytic performance at all testtemperatures. This feature was suggested to be closely associated with both the amount of MgOand preparation method (sol-gel
