Abstract

The invention discloses a nano-porous copper loaded ultrafine oxide copper nanowire composite material and a preparation method and application thereof. The material is a rod, and comprises an amorphous basal body, nano-porous copper covering the amorphous basal body, and ultrafine copper oxide nanowires loaded on the surface of the nano-porous copper; the amorphous basal body is CuxZryAlz alloy component, wherein x, y and z are atomic percents; x is not bigger than 50 and not smaller than 45, y is not bigger than 50 and not smaller than 45, z is not bigger than 10 and not smaller than 5; x+y+z is 100; the nano-porous copper has the layer thickness of 85-135 microns, the ligament width of 118-138 nm and the aperture size of 30-100 nm; the nanowires are 4-10 microns long and 5-15 nm wide; and every 20-30 nanowires are clustered as one bundle. The copper oxide nanowires are constructed on the nano-scale basal body for the first time. Nanowire copper oxide is tightly combined with the surface of the nano-porous copper metal, so that the prepared material achieves efficient photocatalytic degradation of organic dye.

Description

Technical field: [0001] The invention relates to the technical field of copper oxide materials, in particular to a nanoporous copper-supported ultrafine copper oxide nanowire composite material, a preparation method and application thereof. Background technique: [0002] Due to industrialization and population increase in recent years, various environmental problems, especially the pollution of aquatic biological systems, have become urgent problems to be solved internationally. The Advanced Oxidation Process (AOP) can rapidly degrade various insoluble organic substances in sewage. AOP includes ozonation, photocatalysis and Fenton's method. Photocatalysis is a relatively new interdisciplinary field. Semiconductor photocatalysis as a cost-effective and green technology provides a new route for environmental purification and solar energy conversion. Among various semiconductors, copper oxide (CuO) has a narrow bandgap (about 1.2eV) and good electrochemical activity because ...
