Synthesis of nanostructured SnO and SnO2 by high-energy ...

In this paper, we have shown the possibility of obtaining tin oxides (SnO and SnO 2) from the milling of tin powder with stearic acid, followed by annealing at specific temperatures. The high-energy ball milling process of tin with stearic acid is found to be an effective way to obtain the nanostructured β-Sn.

THE GAS-SENSING POTENTIAL OF NANOCRYSTALLINE SNO

A significant feature is that during milling in the presence of water a high number of OH groups are formed at the surface. After heat-treatment the OH bonds of adjacent SnO2 grains are probably transformed into Sn-O-Sn bridges. On exposure to H2S gas, the SnO2 film, prepared from anhydrous powder, has higher sensitivity than the SnO2 film ...
