Insight into the influence of rare-earth promoter (CeO2, La2O3, Y2O3, and Sm2O3) addition toward methane dry reforming over Co/mesoporous alumina catalysts

Co/mesoporous alumina (MA) catalysts promoted with Ce, La, Sm, and Y were evaluated via methane dry reforming. Co particle dispersion on MA was evidently improved after promoter incorporation, resulting in smaller crystallite size and lesser Co agglomeration. Unlike Ce and La promoters, the employme...
