Ex situ and in situ decompositions of ammonium and tetraalkylammonium thiomolybdates were used to synthesize unsupported MoS 2 and CoMo catalysts. The ex situ activation was performed under a H 2 S/H 2 flow whereas the in situ activation consists in decomposing the thiosalt precursors in the presenc
