| Abstract: | This paper used the hydrothermal method to synthesize SnO2-TiO2 nanorod heterojunction catalyst,which has a unique nanorod and heterogeneous junction structure.This unique structure that was proved by means of Photocurrent,X-ray photoelectron spectroscopy (XPS),X-ray diffraction (XRD),and transmission electron microscope (TEM) can effectively prevent the recombination of photogenerated electrons and holes.The as-prepared material can significantly improve the degradation efficiency of methyl orange (MO) by UV light when it is used as the photocatalyst. |
