(510d) Photocatalytic Removal of Waterborne Pollutants By Electrospun Nanofibers of Graphitic Carbon Nitride and Titanium Nitride

In this work, we have fabricated the of composite plasmonic nanofiber mat consisting of graphitic carbon nitride (g-C₃N₄) and titanium nitride (TiN) nanoparticles for photocatalysis. The nanofiber mat was fabricated by electrospinning g-C₃N₄, TiN nanoparticles and polyvinylidene fluoride (PVDF) and it demonstrated well flexibility without losing the structure. The mat was successfully characterized with SEM, TEM, AFM, FTIR, XPS, XRD and PL spectroscopy. Hexavalent chromium, which is the toxic state of chromium has been successfully reduced by this nanofiber mat under simulated solar light and in presence of trace amount of formic acid. The nanofiber mat also demonstrated well cyclability for hexavalent chromium reduction.
