The invention is directed to a catalyst and a method for making a reforming catalyst for the production of hydrogen from organic compounds that overcomes the problems of catalyst poisoning and deactivation by coking and high temperature sintering, yet provides excellent durability and a long working life in process use. An embodiment is the formation of a unique four-metal ion hexa-aluminate of the formula M1.sub.aM2.sub.bM3.sub.cM4.sub.dAl.sub.11O.sub.19-.alpha.. M1 and M2 are selected from the group consisting of beryllium, magnesium, calcium, strontium, barium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, and gadolinium. M3 and M4 are selected from the group consisting of chromium, manganese, iron, cobalt, nickel, copper, molybdenum, ruthenium, rhodium, palladium, tungsten, rhenium, osmium, iridium, platinum, wherein 0.010.ltoreq.a+b+c+d.ltoreq.2.0. Also, 1.ltoreq..alpha..ltoreq.1. Further, M1.noteq.M2 and M3.noteq.M4.
