“…Rh is one of the most preferred components in terms of catalytic activity, syngas selectivity, and coking resistance, but researchers have produced an incredibly short contact time reaction using Rh impregnated foam catalyst and obtained extremely high syngas selectivity [8]. Even in the light of this, as one of the relatively lower-activity metals, nickel has become the industry standard catalytic metal used in steam methane reforming because of its relatively low cost, wide availability and sufficient catalytic activity, all combining to make it the most cost-efficient choice [3,9,10].…”
