Chemists in the US have created a molecule that closely resembles the key active portion of molybdenum disulfide, an important solid industrial catalyst that shows promise for the generation of hydrogen from water. There are relatively few catalytically active sites on molybdenum disulfide crystals, so a molecular analogue could lead to a catalyst with similar chemistry but a higher density of active sites. In addition, a molecular mimic can be experimented upon more easily, to improve efficiencies and unpick the catalytic mechanism - something that is still unclear for MoS2.
