[0047] Example 1
[0048] The method for preparing a nano-silver-loaded copper oxide composite material described in this embodiment, the specific steps are as follows: figure 1 As shown in the process flow, 32.01gCu(NO 3 ) 2 ·3H 2 O was added to 1000 ml of deionized water, and 2.3 g of sodium dodecylbenzene sulfonate was added, and stirred evenly. Adding 300ml of 1mol / L sodium hydroxide solution dropwise, electromagnetic stirring for 40 minutes, washing and drying to obtain nanometer copper oxide. Disperse the obtained nano copper oxide powder in 400ml 0.2mol / L AgNO 3 In the aqueous solution, ultrasonic treatment at 60°C for 15 minutes results in uniform dispersion, and then 100ml of 1.2mol / L hydrazine hydrate solution is added dropwise to the above aqueous solution under ultrasonic treatment. After 15 minutes of reaction, the precipitate is aged and washed. And vacuum drying at 100°C for 8 hours to prepare silver-loaded copper oxide nanomaterials. The average particle size is ...
