Abstract

The invention discloses a nano-porous copper-silver bimetal / bimetal oxide and a preparation method and application of the nano-porous copper-silver bimetal / bimetal oxide. Nano-porous copper-silver bimetal obtained after an amorphous matrix is dealloyed is used as an anode for electrochemical oxidation, the finally-obtained bimetal oxide is loaded to the surface of the nano-porous copper-silver bimetal in a nanowire shape, and the amorphous matrix is the CuxZryAgz alloy ingredient, wherein x, y and z are atomic percents, x is larger than or equal to 35 and is smaller than or equal to 45, y is larger than or equal to 35 and is smaller than or equal to 45, z is larger than or equal to 10 and is smaller than or equal to 30, and the sum of x, y and z is 100. The preparation process is simpler, the mechanical integrity is better, cyclic reuse can be achieved, bar products are easy to recycle, and secondary pollution of powder products is avoided.

Description

Technical field: [0001] The invention belongs to the technical field of preparation of nanoporous materials and antibacterial agents, and in particular relates to a nanoporous copper-silver double metal / double metal oxide and its preparation method and application. Background technique: [0002] With the continuous development of science and technology and the continuous improvement of the quality of life, people are increasingly pursuing a healthy and comfortable living environment. However, bacteria are ubiquitous and pervasive, and there are many harmful bacteria that cause disease, which seriously threaten human health. In order to improve the living and working environment and protect human health, the research and development of new, high-efficiency and durable antibacterial materials has become a current research hotspot. Inorganic antibacterial agents have been widely used because of their advantages such as wide antibacterial spectrum, low toxicity, good heat resist...
