Abstract

A hierarchical pore nanoporous copper loaded cuprous oxide nanowire composite material is a thin belt and comprises an amorphous matrix, nanoporous copper which covers the amorphous matrix, and a porous cuprous oxide nanowire which is loaded on the surface of the nanoporous copper, wherein the cross section of the composite material is of a five-layer structure, and the intermediate core layer isthe amorphous matrix; the nanoporous copper covers the surfaces of two sides of the intermediate core layer; the porous cuprous oxide nanowire is loaded on the surface of the nanoporous copper at thetwo sides; the nanoporous copper layer at one side is 6-12 microns in thickness; the flexible belt is 20-40nm in width; the pore diameter is 15-30nm; the nanowire layer at one side is 3-12 microns inthickness; the nanowire is 5-10 microns in length and 5-10nm in width; nanopores being 0.5-2nm are distributed in the nanowires. The method is simple in processes, and short in preparation period; theprepared composite material is high in mechanical completeness and can be recycled, so that the economic benefit is improved.

Description

Technical field: [0001] The invention relates to the technical field of cuprous oxide materials, in particular to a multi-level nanoporous copper-loaded cuprous oxide nanowire composite material and a preparation method thereof. Background technique: [0002] Cuprous oxide is a p-type narrow bandgap (2.17eV) semiconductor material with an active electron-hole pair system, so it exhibits good catalytic activity and has shown great application potential in photocatalytic degradation of organic dyes. . It is well known that the degradation performance of catalysts often depends on their effective surface area and porosity. Therefore, nanonization and porosity are effective methods to improve the photocatalytic degradation performance of cuprous oxide. [0003] Prior art, Publication No. CN104556198A "A Continuous Production Method of Ultrafine Cuprous Oxide and Its Application". In this patent, the prepared product is cuprous oxide nanopowder, and the preparation process need...
