Catalysis Engineering based on Polyoxometalates

Title : Catalysis Engineering based on Polyoxometalates

Abstract:

Polyoxometalates chemistry is a key emerging area that promises the development of a new generation materials which finds numerous applications in the areas of material science, medicine and catalysis. A discrete class of metal-oxygen clusters, Polyoxometalates (POMs) have gained tremendous attention for their opportune shapes, sizes, composition and structural diversities. Their best advantage is their ability to modify at molecular level, giving rise to second, third and fourth generation materials. In this context, the Transition Metal Substituted Polyoxometalates (TMSPOMs) have attracted significant attention in catalysis due to tuning of redox properties and ability to show variable oxidation states. The unique catalytic activity makes them promising environmentally benign heterogeneous catalysts.

 In the present talk, engineering of catalysts based on Lacunary Phosphotungstates (PW₁₁ & PW₁₀) and Transition metal, Copper (Cu) will be discussed for example mono copper substituted phosphotungstate (PW₁₁Cu), di copper substituted phosphotungstate (PW₁₀Cu₂), ligand (L = imidazole & s-phenylethylamine) functionalized copper substituted phosphotungstate (PW₁₁Cu-L) and supported PW₁₁Cu will be discussed. Their catalytic activity for one of the industrially important organic transformations, oxidation/epoxidation of styrene will be conversed. Further kinetics and mechanistic aspects will also be discussed.

Audience take-away:

• The diversity in the designing of catalyst based on polyoxometalates are open towards developing highly product selective catalyst for industrial important reactions, such as hydrogenation and oxidation.
• By taking the advantages of their properties, there is a large scope to explore new applications for example, Biomass conversion, which is an upcoming field in current scenario. 
• It is useful for the audience to develop hybrid compounds based on POMs for example, supported TMSPOMs and functionalized TMSPOMs, by different chiral moieties, which will be helpful especially for asymmetric oxidation and water oxidation.
