Abstract

Abstract:

Si nano-materials are wildly used in the field of photocatalyst, solar cell, photodetector due to their excellent photo-absorption ability. So the controlled and large-scale synthesis of one dimensional Si nano-materials becomes the key which affects their applications. In this report, we used a simple chemical vapor deposition (CVD) method to grow large-scale Si nanowires (SiNWs) on molybdenum (Mo) nets substrate. And the characteristics of SiNWs were detailedly analyzed by scanning electron microscope, transmission electron microscope, X-ray diffraction and Raman spectrum. Moreover, the photocatalytic properties of as-grown SiNWs were examined by the photodegradation of Rhodamine B and Methylene Blue under low power ultraviolet (UV) light. In addition, the results show that SiNWs growing on Mo nets substrate have a high photodegration efficient for organic dyes.

Key words: Si nanowires, CVD, Mo nets substrate, photocatalyst
