Abstract

A hierarchical porous nanoporous copper-loaded cuprous oxide nanowire composite material. The composite material is a thin strip and includes an amorphous matrix, nanoporous copper covering the amorphous matrix, and porous oxide nanowires loaded on the surface of the nanoporous copper. Copper nanowires. Among them, the composite material has 5 layers in cross section, the middle core layer is an amorphous matrix, the surfaces on both sides of the middle core layer are covered with nanoporous copper, and the nanoporous copper surfaces on both sides are loaded with porous cuprous oxide nanowires. Among them, the thickness of the nanoporous copper layer on one side is 6 to 12 μm, the width of the ligament is 20 to 40 nm, the pore size is 15 to 30 nm, the thickness of the nanowire layer on one side is 3 to 12 μm, the length of the nanowire is 5 to 10 μm, and the width is 5 to 10 nm; the nanowires are distributed It has nanopores with a size of 0.5~2nm. The invention has simple process and short preparation cycle; the prepared composite material has good mechanical integrity, can be recycled and reused, and the economic benefits are 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...
