Abstract

The invention relates to a molybdenum oxide nano fiber paper and a preparation method thereof, belonging to the technical field of inorganic nano functional materials. The invention aims to prepare a large-area molybdenum oxide nano fiber paper on a hydrophobic substrate by a hydrothermal process and a self-assembly technique. The molybdenum oxide nano fibers prepared by the hydrothermal process have uniform size and high repeatability; the length of the single molybdenum oxide nanobelt can reach 500 mu m above; and the fiber paper self-assembled from the molybdenum oxide nano fibers has the advantages of regular growth, high flexibility, high practicality, excellent uniformity and excellent repeatability, and is applicable to the aspects of photoelectricity, environmental cleaning treatment and the like. Besides, the preparation method has the advantages of low raw material consumption, high yield, short production cycle, simple preparation process and low cost, and is suitable for industrialized application and mass production.

Description

technical field [0001] The invention belongs to the technical field of inorganic nanometer functional materials, and relates to a metal oxide nanometer semiconductor material, in particular to a molybdenum oxide nanofiber paper and a preparation method thereof. Background technique [0002] In recent years, metal oxide semiconductors (such as ZnO, CuO, Fe 2 o 3 、WO 3 、TiO 2 , SnO 2 etc.) have been widely researched and applied in many fields such as photoelectricity, photocatalysis, environmental purification, gas sensitive detection, and solar cells due to their special wide bandgap, high surface-to-volume ratio, and porous structure. However, in the application process of these materials, there are still problems such as complex preparation process, impure product, poor repeatability, and size inhomogeneity. Therefore, in order to solve these problems, people continue to explore new materials and their preparation processes. Molybdenum oxide (MoO 3 ) Nanomaterials, a...
