Abstract :

Metal sulfide bond plays very important, complicant and interesting role in metal sulfide complexes in reacting with organic molecules or catalyzing coupling reactions as well as electrocatalyzed reductive reactions. Previous study on the mechanism of metal dithiolenes catalyzed hydrogen evolution shows that metal hydride intermediates are necessary to be formed by either directly absorbing proton or transferring H from sulfur atom to metal center. One of our study found that Mo disulfide pyridine complex can be an efficient electrocatalyst in hydrogen evolution reactions, but no Mo-H bond can be formed during the whole mechanism because Mo hydride intermediates are not stable. Moreover, in neutral Ni bis(dithiolene) and Co bis(dithiolene) electrocatalyzed H2 evolution reaction, metal hydride complexes are difficult to be formed due to very low stability. However, for anionic Mo bis(dithiolene) photocatalyzed H2 evolution reaction, Mo-H can be formed easily since this anionic intermediate is stable. Our study aimed to understand these phenomena.
