Description

[0001] Technical field: [0002] The invention relates to the technical field of cuprous oxide materials, in particular to a nanoporous copper-loaded porous cuprous oxide nanosheet composite material and a preparation method thereof. [0003] Background technique: [0004] 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. [0005] Prior art, publication number CN102965711B "Preparation method of cuprous oxide nano flake powder material by anodic oxidation two-step method", in this patent, copper foil is used as the base to grow cuprous...
