In this study, we report a facile synthetic protocol for the fabrication of well-dispered porphyrin nanorods on the surface of graphene nanoplates (GNPs) by surfactant-assisted self assembly of tetrakis (4-carboxyphenyl) porphyrin (TCPP). The formation and crystalisation of GNPs-supported TCPP nanorods were successfully characterized by SEM, XRD, FTIR, UV-vis and fluorescence spectroscopy. The assembled TCPP nanorods with a 50 nm diameter and ∼250 nm in length are well distributed on the GNPs and was confirmed by electron microscopy i.e SEM and TEM. The resulted hybrid material shows enhanced visible-light photocatalytic activity compared to free standing TCPP nanorods toward the degradation of Rhodamine B (RhB). In addition, the photodegradation mechanism of RhB when using GNPs-supported TCPP nanorods catalyst is also proposed.
