Abstract: A method for making a catalyst is provided that features loading a catalytic metal to a support using at least two different precursor compounds of that said metal; and loading the promoter to the support in an amount effective so as to achieve similar promotion as for a comparable catalyst comprising a greater amount of the promoter using only one precursor compound, where the catalytic metal is selected from among Group 8 metals, 9 metal, Group 10 metals, and combinations thereof. The promoter is preferably boron, silver, a noble metal, or combination thereof. Also provided are catalysts made by the method and Fischer-Tropsch processes that include contacting synthesis gas with a catalyst made by the method.
