Abstract

Catalysts having structures containing the Mo₆S₈ cluster (crystalline Chevrel phases, amorphous ternary molybdenum sulfides, and ligated molecular clusters) have been discovered to be active for thiol synthesis from methanol and hydrogen sulfide at 250°C and 1 atm. An amorphous lanthanum molybdenum sulfide material was found to be the most selective catalyst (<80% methanethiol) at low conversions. CO₂, CO, CS₂, and CH₄ were the major by-products in these studies.
