Hierarchical flower-like MoS{sub 2} spheres with high purity were synthesized by hydrothermal method using WO{sub 3} nanorods or H{sub 2}WO{sub 4} as an additive. The flower-like spheres were about 1 {mu}m in diameter and built up with MoS{sub 2} thin flakes with thickness of several nanometers. Energy disperse X-ray spectrum showed that the spheres were only composed of Mo and S with atomic ratio of 2:1. Powder X-ray diffraction result further indicated that the products were MoS{sub 2}. The reaction mechanism is discussed and suggested that tungstenic acid played an important role on the formation of flower-like MoS{sub 2} spheres.
