Cerium promoted ni/mgo catalyst for biogas dry reforming

In the present work, different loadings of cerium promoted Ni/MgO catalyst for the biogas dry reforming reaction was studied. XRD diffraction pattern of fresh 5 wt% Ce-Ni/MgO catalyst showed peaks representing MgO at 2θ = 37.00 and NiO at 42.99, 62.41, 74.84 and 78.79. BET characterization of b...
