A perspective on nanocluster catalysis: polyoxoanion and (n-C4H9)4N+ stabilized Ir(0)∼300 nanocluster ‘soluble heterogeneous catalysts’
TL;DR: In this article, the experimental observations relating to three principle questions concerning these soluble-oxide-supported, Ir(0)∼300 nanocluster catalysts are reviewed: (i) their catalytic activity (in a prototypical structure-insensitive reaction, cyclohexene hydrogenation); (ii) their lifetime; and (iii) their thermal stability.
