Article Preview

We report the synthesis of the taper-like BiVO4 nanorods by employing a solid-state grinding synthetic strategy. The X-ray diffraction (XRD) indicates that the as-prepared BiVO4 nanorods were crystallized in a monoclinic system. The diameter and length of taper-like nanorods are confirmed by the scanning electron microscopy (SEM) technology. The diameter and length of the taper-like nanorods are 100 nm and 1 μm, respectively. And the photocatalytic activity of the taper-like BiVO4 nanorods was evaluated by measuring the degradation of methylene blue (MB) in water under sunlight irradiation. MB was degraded nearly to nothing under sunlight irradiation for 120 min at room temperature in air. These results indicate the as-prepared product is a good sun-driven photocatalyst. In addition, the degradation mechanism of methylene blue over BiVO4 nanorods was tentatively investigated.
