h ' (CH4) and 870 "C. The promoted catalysts were studied by XRD, TPR and XPS techniques. Ceria suppressed the growth of nickel crystallites, enhancing the stability and performance of the catalyst.
## Abstract **BACKGROUND:** The metal dispersed over a support can be present as small crystallites with sizes less than 5 nm. The smaller crystallites favour aromatization while larger crystallites favour cracking/hydrogenolysis. Sintering results in the agglomerization of smaller metal crystallit
