Embodiment 1
[0029] The specific steps of preparation are:
[0030] Step 1, respectively prepare 200g / L copper sulfate pentahydrate aqueous solution, 150g / L sodium hydroxide aqueous solution and 150g / L glucose aqueous solution.
[0031] Step 2, according to the volume ratio of copper sulfate pentahydrate aqueous solution, sodium hydroxide aqueous solution and glucose aqueous solution to be 0.8:1.2:0.8, add sodium hydroxide aqueous solution dropwise to copper sulfate pentahydrate aqueous solution, and vigorously stir for 3min; Wherein, the stirring speed during vigorous stirring was 1000 r / min to obtain a mixed solution. The mixed solution was then stirred at 45° C. for 7 minutes, and an aqueous glucose solution was added to the mixture under stirring, and an intermediate reaction solution was obtained after stirring and reacting for 25 minutes.
[0032] Step 3, after the intermediate reaction solution is centrifugally cleaned twice, the obtained solids are dispersed in deionized water; wh...

[0034] The specific steps of preparation are:
[0035] Step 1, respectively prepare 225g / L copper sulfate pentahydrate aqueous solution, 138g / L sodium hydroxide aqueous solution and 175g / L glucose aqueous solution.
[0036] Step 2, according to the volume ratio of copper sulfate pentahydrate aqueous solution, sodium hydroxide aqueous solution and glucose aqueous solution to be 0.9:1.1:0.9, add sodium hydroxide aqueous solution dropwise to copper sulfate pentahydrate aqueous solution, and vigorously stir for 4min; Wherein, the stirring rate during vigorous stirring was 950 r / min to obtain a mixed solution. The mixed solution was then stirred at 48° C. for 6 minutes, and then an aqueous glucose solution was added to the mixture under stirring, and an intermediate reaction solution was obtained after stirring and reacting for 28 minutes.
[0037] Step 3, after the intermediate reaction solution is subjected to centrifugal cleaning twice, the obtained solids are dispersed in deio...

[0039] The specific steps of preparation are:
[0040] Step 1, respectively prepare 250g / L copper sulfate pentahydrate aqueous solution, 125g / L sodium hydroxide aqueous solution and 200g / L glucose aqueous solution.
[0041] Step 2, according to the volume ratio of the copper sulfate pentahydrate aqueous solution, the sodium hydroxide aqueous solution and the glucose aqueous solution is 1:1:1, the sodium hydroxide aqueous solution is added dropwise to the pentahydrate copper sulfate aqueous solution, and vigorously stirred for 5min; Wherein, the stirring rate during vigorous stirring was 900 r / min to obtain a mixed solution. Then, the mixed solution was stirred at 50° C. for 5 min, and an aqueous glucose solution was added thereto under stirring state, and the intermediate reaction solution was obtained after stirring and reacting for 30 min.
[0042]Step 3, after performing centrifugal cleaning on the intermediate reaction solution for 3 times, the obtained solids are dispers...
