Graphical abstractMagnified SEM Micrographs of 0.5 wt% xGnP modified PP/SEBS blends. The figure represents the penetration of SEBS polymer chains between the graphene nanoplatelets in 0.5 wt% xGnP modified PP/SEBS blends. The SEBS helps to form nano-bridges (with diameter around 100 nm) between the adjacent nanoplatelets which prevents the agglomeration tendency of the nanoplatelets.
 | Visible light photocatalytic disinfection of E. Coli with TiO2-graphene nanocomposite sensitized with tetrakis(4-carboxyphenyl)porphyrin Original Research Article Applied Surface Science, Available online 20 July 2015, Pages Rahmatollah Rahimi, Solmaz Zargari, Azam Yousefi, Marzieh Yaghobi Berijani, Ali Ghaffarinejad, Ali Morsali
Graphical abstractTiO2-graphene nanocomposites with different content of graphene were synthesized via a facile one-step solvothermal method. Photoelectrochemical responses of prepared photocatalysts were measured to determine the optimum content of graphene in TG nanocomposites. The results show that the TG nanocomposite with 3% of graphene has the highest photoactivity. This compound was sensitized with tetrakis(4-carboxyphenyl) porphyrin (TGP). The prepared photocatalysts were used for photocatalytic disinfection of E. coli. The results showed that the photocatalytic disinfection of the TG nanocomposite was increased after sensitization with porphyrin. The enhanced photocatalytic performance could be attributed to the synergistic effect between TiO2, graphene and porphyrin sensitizer in the TGP photocatalyst.
