Abstract

Pt-catalyzed hydrogen reduction of $MoS_2$ and $WS_2$ at 1000–1050°C yields new metal-rich sulfides $M_{21}S_8$ and $M_{14}S_5$ (M =Mo or W). The reduction of $MoS_2$ proceeds via the intermediate $Mo_6S_8$. Chevrel phases, $Cu_xMo_6S_8$(x < 4.0) and $Ni_2Mo_6S_8$, are readily prepared by hydrogen reduction of $MoS_2$ in the presence of the ternary metal.
