The synthesis of monoclinic bismuth vanadate nanoribbons and studies of photoconductive, photoresponse, and photocatalytic properties

Large-scale, high-purity and uniform BiVO4 nanoribbons have been synthesized by a facile hydrothermal route without surfactants. The as-prepared BiVO4 nanoribbons were up to hundreds of micrometers in length, 60–80 nm in width, 15–20 nm in thickness, and grew along the [0 1 0] direction. The photoresponse property of BiVO4 nanoribbons was measured under different wavelengths. Their photoswitch behavior was also demonstrated. Furthermore, the nanoribbons showed superior photocatalytic activities in the degradation of eosin Y under visible light irradiation.
