Claim Text:
1. A mixed metal sulfide (MMS) catalyst, comprising: molybdenum sulfide, nickel sulfide, and tungsten sulfide, wherein the catalyst is characterized as having a multi-phased structure comprising five phases: a molybdenum sulfide phase, a tungsten sulfide phase, a molybdenum tungsten sulfide phase, an active nickel phase, and a nickel sulfide phase; wherein the catalyst is characterized as having molar ratios of metal components Ni:Mo:W in a region defined by five points ABCDE of a ternary phase diagram, and wherein the five points ABCDE are defined as: A (Ni=0.72, Mo=0.00, W=0.28), B (Ni=0.25, Mo=0.00, W=0.75), C (Ni=0.25, Mo=0.25, W=0.50), D (Ni=0.60, Mo=0.25, W=0.15), E (Ni=0.72, Mo=0.13, W=0.15); and wherein the mixed metal sulfide catalyst is self-supported.
