abstract: A heterojunction of p-Si(100)/n-ZnO nanorods was fabricated by a simple hydrothermal method. The
photocatalytic activity of this heterojunction was examined by degradation of Rhodamine B (RhB) under
UV light irradiation. The results indicated that the p-Si(100)/n-ZnO nanorods heterojunction exhibits
higher photocatalytic activity compared to that of a glass/n-ZnO nanorods. The inner electric field created
by the space charge region of heterojunction will oppose the recombination of photogenerated electrons
and holes. Furthermore, this heterojunction serves as a convenient recyclable and effective photocatalyst.
The photodecomposition rate of RhB after 5 cycles is negligible change in an experiment using this
heterojunction.
