Polyoxometalate clusters: catalytic chemistry in solution and condensed states
Grant number: DP0450134
Polyoxometalate cluster anions are soluble metal-oxygen clusters that are cheap, robust and non-toxic. Conditions for systematic tuning of redox potentials over the range +2 to -3 V have become accessible via certain photo-active polyoxometalates. The same system can provide powerful oxidants (that rival chlorine) and powerful reductants (that rival potassium). The program will take advantage of this unique range of properties to explore:- (i) coupling of photo- and electro-chemical processes into effective catalytic cycles; (ii) photo- and electro-chemical processes in ionic liquid solvents; (iii) synthesis and redox reactivity of nanoparticles stabilised by polyoxometalates.
