Oxidized g-C₃N₄/polyaniline nanofiber composite for the selective removal of hexavalent chromium.

ABSTRACT: Nanomaterials with selective adsorption properties are in demand for environmental applications. Herein, acid etching and oxidative decomposition of melon units of graphitic carbon nitride (g-C₃N₄) was performed to obtain the oxidized graphitic carbon nitride (Ox-g-C₃N₄) nanosheets. Ox- g-C₃N₄ nanosheets were further decorated on the polyaniline nanofiber (Ox-g-C₃N₄/Pani-NF). Ox-g-C₃N₄/Pani-NF was well characterized and further applied for a selective removal of hexavalent chromium (Cr(VI)) form aqueous solution. The zeta potential analysis indicate that the surface of Ox-g-C₃N₄/Pani-NF was positively charged which could be beneficial to bind anionic Cr(VI) io
