Coinage metal nanoclusters: synthesis, structure and reactivity
Grant number: DP150101388 | Funding period: 2015 - 2017
Metal catalysts play important roles in the multi-billion dollar production of many industrial and fine chemicals used in wide-ranging applications including pharmaceuticals, insecticides and polymers. Despite the importance of metal catalysed reactions, the molecular details of such processes remain poorly understood. Breakthrough studies highlight that reactions previously thought to be catalysed by discrete metal catalysts are in fact catalysed by metal nanoclusters. This project involves the application of advanced mass spectrometric and computational methods to explore the formation and reactivity of copper, silver and gold nanoclusters. Identification of key reactive intermediates will..View full description
