Duong Duc La obtained his MSc degree in Nanotechnology of hybrid materials for superhydrophobic surface and hydrogen sensing at HanYang University (Korea) in 2010. Now he is pursuing his PhD degree at RMIT University (Australia) in the group of Dr. Sheshanath Bhosale. In his study, he mainly focuses on fabricating hybrid materials of inorganic and organic (supramolecules) compounds via novel approach of self-assembly for photocatalysis, sensing and electronics devices. He is also working on the fabrication of graphene-based materials for photovoltaic and adsorption applications. He published 25 peer-reviewed papers so far.
In this study, we report a facile synthetic protocol for the fabrication of well-dispered porphyrin nanofibers on the surface of graphene nanoplates (GNPs) by argiline-assisted self assembly of tetrakis (4-carboxyphenyl) porphyrin (TCPP). The formation and crystalisation of GNPs-supported TCPP nanofibers were successfully characterized by SEM, XRD, FTIR, UV-vis and fluorescence spectroscopy. The assembled TCPP nanofibers with a 50 nm diameter and several micrometers in length are well distributed on the GNPs and were 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 Rohdamine B (RhB) and methyl orange. In addition, the photodegradation mechanism of dyes when using GNPs-supported TCPP nanofibers catalyst is also proposed.
