Abstract
The invention discloses a preparation method of a silver oxide doped copper oxide antibacterial agent rich in oxygen vacancies, which comprises the following steps: 1, dissolving sodium hydroxide, polyvinylpyrrolidone and sodium citrate in deionized water, then adding copper chloride, heating and stirring to obtain copper oxide; 2, dissolving copper oxide and silver nitrate in deionized water, and collecting and drying the precipitate to obtain precursor powder; and 3, grinding the precursor powder, and calcining to obtain the silver oxide doped copper oxide antibacterial agent rich in oxygen vacancies. Copper oxide is prepared firstly, then copper oxide and silver nitrate are heated and stirred and then calcined, the silver oxide doped copper oxide antibacterial agent rich in oxygen vacancies is obtained, the oxygen vacancies can enhance the electron transfer capacity of the surface of a catalyst, sufficient active oxygen species are kept on the surface of the catalyst, efficient catalytic reaction is maintained, and the antibacterial effect of the antibacterial agent is improved. And active oxygen species are generated under the dark condition, so that pathogenic microorganisms are inactivated under the dark condition.
