Abstract

The invention discloses a synthesis method of a carbon fiber cloth@porous ZnO two-dimensional nanosheet array@Ag2O nanoparticle ternary heterojunction. The carbon fiber cloth@porous ZnO two-dimensional nanosheet array@Ag2O nanoparticle ternary heterojunction is obtained from carbon fiber cloth, a zinc source and silver nitrate only through hydrothermal reaction, pyrolysis and impregnation. The process is simple, economic and easy to operate. The prepared ZnO nanosheet array is porous and high in specific surface area, and facilitates pollutant adsorption and photon-generated carrier transfer. Ag2O loaded on the surfaces of ZnO nanosheets expands the photo-response range of ZnO and changes the response characteristics of the surfaces of the ZnO nanosheets. The flexible and porous carbon fiber cloth substrate not only can capture photo-generated electrons and promote photo-acoustic carrier separation, but also is convenient to separate and collect in the recycling process. The flexible, large-size and high-specific-surface-area product has application potential in the aspects of photocatalytic degradation of environmental organic pollutants, biosensing and the like.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to a synthesis method of carbon fiber cloth@porous ZnO two-dimensional nanosheet array@Ag2O nanoparticle ternary heterojunction. Background technique [0002] The technical development of functional materials has prompted the research in the field of materials chemistry to develop in the direction of designing nanomaterials with controlled morphology and composition. Among them, structure plays a central role in the field of chemistry and materials science. In particular, the preparation of inorganic nanostructured materials with precise sizes, shapes, and dimensions has rapidly advanced our understanding of the dependence of material properties on structure and size. Among nanostructures with different morphologies, two-dimensional nanosheets, due to their unique structural factors such as thinner thickness and higher specific surface area, not only can assemble diverse stru...
