Abstract

The diameter-controllable SnO₂ porous structures were fabricated by templating against the polystyrene nanospheres. The porous SnO₂ nanostructures present efficient photocatalytic performance in degradation of MO under violet light, which has rarely been reported in the past. The photocatalytic ability can be enhanced through decreasing the porous diameter. Spectral examinations and analyses reveal that the porous structures and the existing oxygen vacancies are responsible for the appearing photocatalytic ability. Such porous structure is also expected to present good performance in gas sensing and electrochemical properties.
