Poly-oxo anion chemistry
(With Dr. Jingli Xie and Michelle Ma)
These anions are soluble clusters of metal and oxygen atoms whose symmetric structures are related to the insoluble metal oxides (eg Figure 1). As they are cheap, robust and non-toxic, they have potential as new green catalysts. We are studying two aspects:-
It is now possible to study catalytic cycles in the gas phase (!!) by mass spectrometry to obtain new molecular insights. [1]
The clusters are highly photo-active and redox-active (can be oxidised and reduced). These properties have led to very promising and simple photo-catalysts which use light as an energy source (including ones which oxidize H2O to O2: "artificial photosynthesis".[2,3] The redox reactivity of the anions in new environmentally friendly solvents ('ionic liquids') is being explored.[4,5] We are currently searching for new materials, new structures and new chemistry.
