Olive-shaped SnO2 nanocrystals were synthesized successfully via a facile hydrothermal route, using tin dichloride hydrate, oxalic acid dihydrate and polyvinylpyrrolidone as reaction precursors, and showed great potential in the large-scale preparation of SnO2 nanocrystals. The prepared SnO2 nanocrystals were characterized
