1. A method for making a catalyst, comprising:
depositing a precursor comprising a Group 6 metal, a precursor comprising a Group 9 or Group 10 metal, an acid or a base, and a first organic compound on a support material to form a catalyst precursor;
heating the catalyst precursor to a temperature of 250° C. to 1000° C. in an atmosphere having an oxygen content of 20 vppm O2 or less during the heating to form an intermediate catalyst product comprising metal carbides of at least one of the Group 6 metal and the Group 9 or Group 10 metal, the intermediate catalyst product having a pore volume of 0.10 cm3/g or higher; and
depositing a secondary organic compound, different from the acid or the base and the first organic compound, and having a boiling point of 250° C. or higher on the intermediate catalyst product to form a catalyst, the secondary organic compound comprising an alcohol, an amine or a combination thereof.
