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
## Abstract **Summary:** Naβmontmorillonite (MMT) with a cation exchange capacity (CEC) of 90 meq/100 g was converted to MMTβCTAB and MMTβCPC by the intercalation of cetyltrimethylammonium bromide (CTAB) and cetylpyridinium chloride (CPC), respectively. The intercalation of CPC onto the basal space
