Photoelectrochemical Study and Hydrothermal Synthesis of Bismuth Phosphate Nanorods

Bismuth phosphate nanorods with the diameter about 30 nm and length about 1-2 mu m were synthesized by a simple hydrothermal process. The morphology and crystal structure were characterized by SEM, HRTEM and XRD. The results show that the BiPO4 nanorods that have single-crystalline nature with a preferential growth oriented along the [100] direction. Photoelectrochemical measurements show they may be more efficient in photocatalytic degradation of organic pollutants and decomposition of water.
