Abstract

The invention discloses an antimony nanosheet and graphite-like carbon nitride nanosheet composite material and a preparation method thereof. The material is formed by compounding antimony nanosheets and graphite-like carbon nitride in a mass ratio of (2.5: 100)-(10: 100), a sheet-sheet compounding process is realized by adopting a softening chemical method, and the performance of the catalytic material is modulated by controlling the content of Sb. The method has the advantages of simple raw materials and process, uniform product and the like, and the material has better peroxidase-like properties.

Description

technical field [0001] The invention belongs to the field of catalytic materials, and in particular relates to a composite material, preparation method and application of Sb-CN nanosheets. Background technique [0002] In recent years, the preparation and properties of antimony nanosheets have been widely studied. Semiconductor nanomaterials refer to ultrafine semiconductor materials with a grain size of nanometers. Due to its own characteristics, nanomaterials play an important role in the fields of optoelectronics, microelectronics, photocatalysis, sensors, detectors, and biological photography. Dresselhaus et al. synthesized amorphous or polycrystalline antimony nanowires on porous anodic alumina templates by vapor deposition technology, and studied their transport properties (HeremansJ, Thrush C M, Lin Y, et al. Transport Properties of Antimony Nanowires [J]. Phys Rev B, 2001, 63(8): 85406-85413). Qian Yitai’s group synthesized antimony nanotubes by using hydrothermal / ...
