摘要：

With the assistance of polyoxometalates (POM). ZnO polyhedra with the mean length of 200 nm and mean diameter of 100 nm are synthesized by a simple solvothermal route in an alkali solution. Parallel experiments without POM were carried out to investigate the formation process of ZnO polyhedra and the results showed that POM played a key role in the formation of ZnO polyhedra. A possible formation mechanism was also proposed. Meanwhile, the as-prepared ZnO powder was used to assemble dye-sensitized solar cells (DSSC) photoanodes, the overall solar-to-electric energy conversion efficiency was up to 2.45%, which were obtained using TiCl4 post-treatment.
