Synthesis of Porous g-C$lt;inf$gt;3$lt;/inf$gt;N$lt;inf$gt;4$lt;/inf$gt; Loaded With Highly Dispersed PANI by Interfacial Polymerization and Its Photocatalytic Performance

Abstract

Polyaniline (PANI) was successfully loaded on porous graphitic carbon nitride (porous g-C 3 N 4 ) by interfacial polymerization of aniline monomers. The structure, morphology and properties of the prepared samples were characterized by XRD, FTIR, SEM, TGA, UV-Vis and Electrochemical Impedance Spectroscope (EIS).Photocatalytic degradation of methylene blue was investigated to determine the photoactivity of the catalyst. The porous g-C 3 N 4 showed good dispersion and interfacial adhesion to PANI, which improved the photocatalytic degradation of methylene blue and thermal stability. The improved photocatalytic activity could be attributed to the improved visible light utilization, oxidation power and electron transport property.
