    Abstract:

    The behaviours of two uranyl peroxide nanoclusters in water heated to 180 °C were examined by in situ Raman spectroscopy. Aqueous solutions containing the nanoscale uranyl peroxide cage clusters U 60 , [(UO 2 )(O 2 )(OH)] 60 60− , and U 60 Ox 30 , [{(UO 2 )(O 2 )} 60 (C 2 O 4 ) 30 ] 60− , were monitored by in situ Raman spectroscopy during stepwise heating to 180 °C. In solutions containing U 60 , clusters persist to 120 °C, although conversion of U 60 to U 24 , [(UO 2 )(O 2 )(OH)] 24 24− , o…
