Significant role of thorny surface morphology of polyaniline on adsorption of triiodide ions towards counter electrode in dye-sensitized solar cells

Abstract

This paper investigates polyaniline (PANI) adsorption behavior towards triiodide ion (I3-) solution in acetonitrile. Two different types of PANI, namely PANI emeraldine salt (PANI ES) and nanostructured PANI ES (NPES)...

Magnetic Nitrogen-Doped Porous Carbon Nanocomposite for Pb(II) Adsorption from Aqueous Solution

“…The Freundlich isotherm model is well known, assuming the heterogeneous adsorption of adsorbate ions on the surface of the adsorbent through energetically asymmetrical adsorption sites [ 44 , 45 ]. In contrast, the Langmuir isotherm model assumes the monolayer and homogeneous adsorption of ions through energetically identical sites [ 46 , 47 , 48 ].…”

Contribution of the lamellar morphology to the photocatalytic activity of alkaline-hydrothermally treated titania in rhodamine B photodegradation

“…The bcl morphology has been successfully synthesized using a reverse micelle templating method for oxide materials such as silica- and alumina-based materials, 29–34 and also for polymeric materials such as polyaniline. 35,36 However, some reports on soft-templating TiO 2 synthesis produced high surface area particles, but they still have an irregular morphology. 37…”

“…The bcl morphology has been successfully synthesized using a reverse micelle templating method for oxide materials such as silica-and alumina-based materials, [29][30][31][32][33][34] and also for polymeric materials such as polyaniline. 35,36 However, some reports on soft-templating TiO 2 synthesis produced high surface area particles, but they still have an irregular morphology. 37 This study used alkaline-hydrothermal treatment using NH 4 OH solution without a templating agent to produce open channel pore structure TiO 2 particles with a high surface area.…”

Macroemulsion-mediated synthesis of fibrous ZnO microrods and their surface morphology contribution to the high photocatalytic degradation rate

“…Compared with other synthesis methods, the hydrothermal/ solvothermal process provides a simple and convenient way to control ZnO nanostructures' size, shape, and morphology with a relatively high yield. 38 In our research group, we successfully prepared different materials (polyaniline, 39,40 silica, [41][42][43][44] alumina, 45,46 and zinc oxide 14 ) with a controllable morphology using the macroemulsion-mediated solvothermal method. Recently, the synthesis of ZnO within a macroemulsion resulted in holey ZnO nanosheets.…”
