Polyoxometalate Clusters: Catalytic Chemistry in Solution and Condensed States

聚氧簇阴离子是廉价、稳定且无毒的可溶性金属-氧簇。 在+2至-3 V范围内系统调节氧化还原电位的条件已经通过某些光活性聚氧乙烯酸盐变得可获得。 同样的系统可以提供强氧化剂（与氯竞争）和强还原剂（与钾竞争）。 该计划将利用这一独特的属性范围来探索： (i)将光化学和电化学过程耦合成有效的催化循环; (ii)离子液体溶剂中的光化学和电化学过程; (iii)通过聚氧乙烯酸盐稳定的纳米颗粒的合成和氧化还原反应性。

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.
