Abstract
For the first time, the catalytic stability of cobalt metal, nitride, and phosphide phases supported on MgO was compared for dry reforming of methane. The initial CH4 conversions for Co/MgO, Co4N/MgO, and Co2P/MgO catalysts were 88.1, 87.7 and 86.0%, respectively. However, after 15 h of testing, these values gradually decreased to 69.9, 75.0 and 79.4%, respectively. The Co2P catalyst demonstrated superior stability compared to the Co and Co4N catalysts. The enhanced stability of the Co2P/MgO catalyst was attributed to its smaller particle size and a lower ratio of CH4 and CO2 dissociation rates.
