Embodiment 1
[0024] 1) Put 60mL of glycerol and n-dibutyl adipate mixture (volume ratio 2::1) into a three-necked flask, add 2.50g of copper formate solid powder, and add cetyltrimethylammonium bromide at the same time (CTMAB) 0.500 g, the mixture was made into a suspension under constant stirring.
[0025] 2) Slowly increase the temperature of the reaction mixture during rapid stirring. When the temperature rises to 390K, control the temperature to no longer rise, continue to stir and react at 390K for 80 minutes, and naturally cool to room temperature to obtain nano-cuprous oxide of the suspension.
[0026] 3) Dilute the suspension obtained in step 2) with 60 mL of absolute ethanol or acetone, filter under reduced pressure, and then wash with an appropriate amount of absolute ethanol or acetone for 4 times
[0027] 4) Put the cleaned cuprous oxide powder into a vacuum drying oven, and vacuum-dry at 350K for 480 minutes to obtain red nano-cuprous oxide powder microcrystals.

Embodiment 2
[0030] 1) Put 60mL of glycerol and n-dibutyl adipate mixture (volume ratio 2::1) into a three-necked flask, add 2.50g of copper formate solid powder, and add sodium dodecylbenzenesulfonate (SDBS ) 0.500g, make the mixture into a suspension under constant stirring.
[0031] 2) Slowly increase the temperature of the reaction mixture during rapid stirring. When the temperature rises to 400K, control the temperature to no longer rise, continue to stir and react at 400K for 90 minutes, and naturally cool to room temperature to obtain nano-cuprous oxide of the suspension.
[0032] 3) Dilute the suspension obtained in step 2) with 50 mL of absolute ethanol or acetone, filter under reduced pressure, and then wash with appropriate amount of absolute ethanol or acetone for 3 times
[0033] 4) Put the cleaned cuprous oxide powder into a vacuum drying oven, and dry it in vacuum at 350K for 480 minutes to obtain red nano-cuprous oxide powder crystals

Embodiment 3
[0036] 1) Put 60mL of glycerol and n-dibutyl adipate mixture (volume ratio 2::1) into a three-necked flask, add 2.50g of copper formate solid powder, and at the same time add 0.400g of polyvinylpyrrolidone (PVP), in The mixture was made into a suspension with constant stirring.
[0037] 2) Slowly raise the temperature of the reaction mixture during rapid stirring. When the temperature rises to 405K, control the temperature not to rise again, continue to stir and react for 95 minutes, and naturally cool to room temperature to obtain a suspension containing nano-cuprous oxide.
[0038] 3) Dilute the suspension obtained in step 2) with 60 mL of absolute ethanol or acetone, filter under reduced pressure, and then wash with an appropriate amount of absolute ethanol or acetone for 4 times
[0039] 4) Put the cleaned cuprous oxide powder into a vacuum drying oven, and dry it in vacuum at 350K for 480 minutes to obtain red nano-cuprous oxide powder crystals
