Photocatalytic Performance of SnO₂ Prepared by Different Precipitants

Abstract:

Parallel flow precipitation has been employed to prepare nanostructured SnO₂. It is found that the specific surface areas and photocatalytic performance of SnO₂ has a strong dependence on the kind of precipitant. The prepared photocatalysts were characterized by BET, XRD, UV-Vis diffuse reflectance and SEM. The results show that SnO₂ prepared by NH₃·H₂O + (NH₄)₂CO₃ has the highest BET surface area and the smallest crystal average size. SnO₂ prepared by NH₃·H₂O + (NH₄)₂CO₃exhibits the best photocatalytic activity. The results of further experiments show that the specific surface area plays an important role in promotion of photocatalytic activity of SnO₂ prepared by NH₃·H₂O + (NH₄)₂CO₃.
