摘要：

In order to overcome existing difficulties, it would make sense to use datalytic precursors already in the sulphided state. Such an approach was used successfully by us in the case of unsupported mixed catalysts prepared by decomposition if bisthiometalato complex. An other method which appears very promising and general for the preparation of sulphide catalysts is described. This method consists in the direct use of metal sulphur cluster (NH4)2Mo3(S) (S2)6[ as precursor for the preparation of molybdenum sulphide based catalysts. It is shown that the utilization of a complex presenting structural and electronic similarities to the MoS2 phase allows the preparation of highly active catalyst. This method should be suitable for other supports and other active phases (e.g. tungsten).
