[0040] A method for preparing a porphyrin-metal complex functionalized carbon nanotube composite material with controllable layer thickness, comprising the following steps:
[0041] 1) anhydrous SnCl 2 0.02mmol and TCPP 0.01mmol were dissolved in a mixed solvent of 8mL absolute ethanol and 4mL DMF to prepare a mixed solution;
[0042] 2) Add 3.5 mg MWCNTs to the mixed solution prepared in step 1), and ultrasonically obtain a uniform dispersion;
[0043] 3) The dispersion prepared in step 2) was subjected to solvothermal reaction in a 20mL tetrafluoroethylene-lined stainless steel autoclave, the reaction temperature was 100°C, and the reaction time was 24h. After the reaction was completed, it was naturally cooled to room temperature and centrifuged. , to obtain a solid product;
[0044] 4) The solid product was washed with DMF and absolute ethanol to remove unreacted substances, and vacuum-dried to obtain MWCNTs@TCPP-Sn nanocomposites.
