SnO 2 nanocrystals were prepared by precipitation in dodecylamine at 100 C, then they were reacted with vanadium chloromethoxide in oleic acid at 250 C. The resulting materials were heat-treated at various temperatures up to 650 C for thermal stabilization, chemical purification and for studying the overall structural transformations. From the crossed use of various characterization techniques, it emerged that the as-prepared materials were constituted by cassiterite SnO 2 nanocrystals with a surface modified by isolated V (IV) oxide species. After heat-treatment at 400 C, the SnO 2 nanocrystals were wrapped by layers composed of vanadium oxide (IV-V mixed oxidation state) and carbon residuals. After heating at 500 C, only SnO 2 cassiterite nanocrystals were obtained, with a mean size of 2.8 nm and wrapped by only V 2 O 5-like species. The samples heat-treated at 500 C were tested as RhB photodegradation …
