“…PAni nanotube base/silica composite 10.3 [25] Crosslinked PAni 13.8 [21] PAni nanoparticles 6.1 [24] PAni nanotubes 9.2 [26] PAni hydrogel 71.2 This work…”

“…In addition, the adsorption capacities of PAni hydrogel were compared with other PAni adsorbents reported in previous works [15], [21], [24], [25] and [26]. From …”

“…Ayad et al reported a crosslinked three-dimensional (3D) PAni gel was synthesized through the thermal crosslinked method [21]. However, it shows a very low adsorption capacity (13.8 mg/g) for cationic dye, MB.…”

Highly ordered polyaniline as an efficient dye remover

“…Only few papers described the PXRD data of PANI below 2y of 20 and elaborated crystallographic orientations of PANI (Bhadra and Khastgir, 2008;Bhadra et al, 2006;Jozefowicz et al, 1989;Pouget et al, 1991). In some of recent reports, the reflection around the 2y value of 6 has been observed, but they were of low intense (Ayad and Zaghlol, 2012;Zhang et al, 2016). The PXRD pattern of the PANI produced by one-pot catalytic polymerization process using H 2 O 2 and FeCl 2 Á2H 2 O is shown in Figure 1(a).…”

Fabrication of a stable Ti/TiO x H y /Sb−SnO 2 anode for aniline degradation in different electrolytes

“…9, the main characteristic bands of polyaniline at 827 cm À1 , 1141 cm À1 , 1301 cm À1 , 1502 cm À1 , 1577 cm À1 could be seen in the FT-IR spectrum, corresponding to CAH vibration out of benzene plane, CAN stretching of ANHA(C 6 H 4 )ANHA, stretching vibration of CAN bond linked with benzenoid ring, benzenoid structure (C@C) and quinoid (C@C, C@N), respectively [45]. However, two new characteristic bands of solid intermediate products appeared at 1416 cm À1 and 1445 cm À1 , attributing to the ring stretching vibrations in a newly formed phenazine segment [46,47]. Therefore, a reasonable mechanism to form the solid intermediate products was speculate (Fig.…”
