Abstract

​Heteropoly compounds (HPC) occupy a singular position inthe catalysis arena, for their composition is akin to that of themany metal oxide-based catalysts used in heterogeneousprocesses. One type of transformation that has long resistedresearch efforts toward commercial processes is the selectiveoxidation of light alkanes (C1−C4). In this respect, HPC can bedesigned rationally and conveniently prepared so as to modifythe catalyst in a controlled way inaccessible with commonmetal-oxide catalysis. Not only do their smaller size and theirstability render them structurally more defined, but several havedisplayed remarkable performance for catalytic conversions.Their availability and low cost make them particularlyinteresting as substrates to supply chemical feedstock. As aresult, the performance of a large series of HPC has beeninvestigated for the oxidation of light alkanes. Considering thatunder the conditions employed (elevated temperature, strongoxidant) those substrates are prone to complete oxidation,catalysts directing selectively the reaction toward partiallyoxidized product remain an open challenge.
