Novel g-C3N4 micro strings with versatile photodegradation ability
首发时间:2013-12-26
Abstract:In this paper, An easy, scalable and environmentally benign chemical method was developed to synthesize micro strings of graphitic-C3N4 (msg-C3N4) through pre-treatment of melamine with HNO3 in alkaline solvent at low temperature. This methodology results in unique strings morphology of msg-C3N4 with higher surface area (290m2g-1). Therefore, msg-C3N4 was used as a photocatalyst under visible light for photodegradation of Rhodamine B, Methyl Blue and Methyl Orange. The msg-C3N4 showed enhanced photodegradation efficiency due to high surface area and favourable bandgap. The first order rate constant for msg-C3N4 was measured that confirms the higher performance of msg-C3N4 in comparison to other reported materials such as g-C3N4, Fe2O3/g-C3N4 and TiO2 nanotubes.
