A method for preparing a bi-component, multi-network nanofibrous aerogel-supported heterojunction photocatalyst includes the following steps. Step 1, preparing ammoniated polyacrylonitrile nanofibers. Step 2, dispersing the ammoniated polyacrylonitrile nanofibers in water to obtain a first solution; dispersing cellulose nanofibers in water to obtain a second solution; and mixing, heating and lyophilizing the first solution with the second solution to obtain a bi-component, multi-network nanofibrous aerogel. Step 3, adding graphite carbon nitride, a ferric-iron containing reagent, 2,5-diaminoterephthalic acid, and the bi-component, multi-network nanofiber aerogel obtained in the step 2 into a N, N-dimethylformamide solvent to obtain a third solution, and carrying out a hydrothermal reaction on the third solution for 8-24 hours to obtain the bi-component, multi-network nanofibrous aerogel-supported heterojunction photocatalyst. |
