[0014] Example: Preparation A functionalized carbon nanotube loaded with Cu 2 O Hexagonal star microcrystalline composite material.
[0015] Reference figure 1 with figure 2 , (1) Add 20 mg of acidified MWCNTs, sodium dodecyl sulfate (SDS) and 5~200 μL 3,4-ethylenedioxythiophene (EDOT) monomer in a container with 20 mL of tertiary distilled water, at room temperature After stirring for 2 h, add 100 mg mL dropwise ?1 Ammonium persulfate aqueous solution, and then continuously stirred for 24 h. After centrifugation, washing and vacuum drying of the resulting product, PEDOT functionalized MWCNTs carrier material was obtained;
[0016] (2) Add 1 g of polyvinylpyrrolidone (PVP) to 13 mL of three times distilled water, and add PEDOT functionalized MWCNTs and 2 mg mL at a mass ratio of Cu / PEDOT functionalized MWCNTs = 1 / 4 ?1 CuSO 4 After stirring the solution magnetically for 2 hours, add the mixed solution of trisodium citrate and sodium carbonate (with a concentration of 0.6 M), cont...
