Porous polymer substrate/TiO2/carbon materials nanocomposite membranes and their photocatalytic properties |
초록 |
Nanocomposite consisting of TiO2 and graphene-MWCNT was prepared in order to enhance the photocatalytic performance. PVA/PAAc/TiO2/graphene-MWCNT was prepared by phase inversion technique to increase the specific surface area of PVA/PAAc substrate. PVA was used as a substrate, which has excellent mechanical properties, nontoxicity, and biocompatibility. PAAc has the negatively charged groups and gives highly acidic properties. The graphene-MWCNT nanocomposite was used as a functional carbon material to improve the electron conducting from TiO2. The photocatalytic activity was evaluated by UV spectrometer based on the degradation of methylene blue solution under UV light irradiation. The enhanced pH sensitive property and photocatalytic activity was attributed to the increased specific area of polymer substrate and the effective electron transferring by graphene-MWCNT. |
