  1. 10 mL/min each reactant at 823 K with Ar diluent (20 mL/min) and 100 mg of catalyst (16–20 mesh). Catalysts marked with an asterisk indicate that the sample was diluted to achieve comparable C3H8 reactant conversion to Fe3Ni. Values are obtained by averaging data from 10–12 h. Selectivity and yield are on a C3H8 basis (including only carbonaceous species). Catalysts are synthesized by atomic ratios corresponding to a 1.67 wt.% Pt1 basis, thus the weight percent of Fe3, Ni1, and Ni3 are 1.43, 0.5, and 1.5, respectively. The nomenclature assigned by subscripts such as in Fe3Ni means that there are three atoms of Fe for every atom of Ni
