石墨相氮化碳的制备及光催化降解罗丹明B
Preparation of graphite carbon nitride for photocatalytic degradation of RhB
摘要
Abstract
Different combinations of precursors were used to synthesis the photocatalyst in this experiment.The characteristics of photocatalysts were investigated by X-ray diffraction,fourier transform infrared,N2 adsorptiondesorption isotherm,photoluminescence and UV-vis diffuse reflection spectroscopy.Comparing the photocatalysts generated by different combinations of the precursors,the photocatalyst prepared by C2H4N4/CON2H4 precursors at the mass ratio of 1 ∶ 1 showed good crystalline,high separation of photogenerated electrons and holes,and good stability.The removal efficiency of RhB with g-C3 N4 prepared by C2 H4 N4/CON2 H4 precursors was the highest after 180 min photocatalytic reaction.The main oxidative species for photocatalytic degradation of RhB were also detected by adding IPA,BQ and EDTA.The result suggested that the · O2-and holes were mainly responsible for the degradation of RhB.关键词
