The preparation of hybrid materials, namely poly(p-anisidine)@Clay (poly (pAnis)@Clay) and poly(p-anisidine)@cetyltrimethylammoniumbromide-Clay (poly(pAnis)@CTAB-Clay), prepared by oxidative polymerization process is presented. The formation of nanomaterials has been confirmed by XRF, XPS, FT-IR, and UV-Vis spectroscopy. Interestingly, the study of the optical band gap energy (E g) evince lowest value of 3.22 eV for poly(pAnis)@CTAB-Clay compared to poly(pAnis)@Clay with 3.26 eV. XRD results demonstrate that the intercalation of the poly(pAnis) into the Clay was confirmed by the increased interlayer spacing, the exfoliation and intercalation forms were affirmed in the TEM images. In addition, the electrochemical behavior indicates that the prepared nanocomposites are electroactive. These results are heartening in respect with the objective to utilize them in the field of technology and research related to the photovoltaics application.
This work investigated the elimination of Methyl Orange (MO) using a new adsorbent prepared from Activated Carbon (AC) with polyaniline reinforced by a simple oxidation chemical method. The prepared materials were characterized using XRD, TGA, FTIR and nitrogen adsorption isotherms. Furthermore, PANI@CA highest speci c surface area values (near 332 m 2 .g − 1 ) and total mesoporous volume (near 0.038 cm 3 .g − 1 ) displayed the better MO removal capacity (192.52 mg.g − 1 at 298 K and pH 6.0), which is outstandingly higher than that of PANI (46.82 mg.g − 1 ). Besides, the process's adsorption, kinetics, and isothermal analysis were examined using various variables such as pH, MO concentration and contact time. To pretend the adsorption kinetics, various kinetics models, the pseudo rst-and pseudo secondorders, were exercised to the experimental results. The kinetic analysis revealed that the pseudo second order rate law performed better than the pseudo rst order rate law in promoting the formation of the chemisorption phase. In the case of isothermal studies, an analysis of measured correlation coe cient (R 2 ) values showed that the Langmuir model was a better match to experimental results than the Freundlich model. By regeneration experiments after ve cycles, acceptable results were observed.
