Abstract
Cationic surfactant assisted polyaniline was synthesized by oxidative polymerization method by varying aniline concentration in the presence of Ammonium per Oxy Disulphate (APS) as oxidant. Here Cetyl trimethylammonium bromide (CTAB) is used as cationic surfactant. The molar ratio of aniline:APS is kept as 2:5 (PC2) and 3:5 (PC3). The samples were characterized by UV-Vis spectrophotometer; Fourier transforms infrared (FTIR) spectrometer, Field emission scanning electron microscopy (FESEM) and Photoluminescence (PL). In UV-Vis characterization peak at 339 nm and 654 nm indicates the п-п* transitions and transition between quinoid and benzoid rings respectively. Small peak at 397 nm is due to the presence of CTAB. The band gap value of PC2 and PC3 are almost same. Images of PC2 and PC3 shows nanoplate like and nanowires like structure respectively. The vibrational bands present in samples have been identified from FTIR spectra. Quenching phenomenon of PL spectra shows low recombination probability and more charge carrier separation rate. The time dependent visible light photocatalytic dye degradation of the Methylene Blue (MB) shows highest adsorbance for sample PC3.
