Article Electrochemical Polymerization of O-Phenylenediamine in the Presence of Metal Salts: Influence of Cu(No3)2 and AgNo3 on Spectroelectrochemical Properties and Morphology(Springer, 2025) Onat, Fatih Ekrem; Akıllı, Aleyna; Kamis, HandanIn this study, the effects of adding Cu(NO<inf>3</inf>)<inf>2</inf> and AgNO<inf>3</inf> metal salts to the polymerization medium on the electrochemical and spectroelectrochemical properties of poly(o-phenylenediamine) (PoPD) were investigated. It was observed that the presence of Cu(NO<inf>3</inf>)<inf>2</inf> or AgNO<inf>3</inf> during polymerization increased the rate of current peak growth, indicating an acceleration of the polymerization process in the presence of metal ions. The cyclic voltammetry responses of the metal/polymer composites differed significantly from those of the pure polymer, confirming the formation of metal/polymer composites. FTIR and UV–vis absorption spectra were analyzed to explore the chemical structure of PoPD, PoPD/Cu, and PoPD/Ag polymer films. SEM and AFM analyses revealed distinct morphological differences between the polymer synthesized in the presence of metal salts and the pure polymer. Spectroelectrochemical analyses demonstrated that the polymer films exhibited reversible color changes from light copper to green, with distinct optical intensities in the UV–vis spectra. The absorbance and current values changed reversibly with the applied potential, with response times of approximately 10 s. Colorimetric analysis based on the CIE system showed unique variations in brightness (L), magnitude (a), and intensity (b) for PoPD, PoPD/Ag, and PoPD/Cu, confirming distinct colorimetric shifts during redox transitions. This study highlights the impact of Cu and Ag salts on the spectroelectrochemical and electrochromic performance of PoPD, revealing potential applications for PoPD composites in advanced electrochromic devices. © 2025 Elsevier B.V., All rights reserved.Other Adsorption-Assisted Photocatalytic Degradation of Anionic Direct Yellow-50 and Cationic Methylene Blue Dyes by Chemically Synthesized Poly(1,5-Diaminoanthraquinone)(2024) Kamış, Handan; Eskizeybek, Volkan; Özler, Ayşenur; Taymaz, Bircan Haspulat; Hancı, Ahmet; Akıllı, AleynaArticle Citation - WoS: 3Citation - Scopus: 3Adsorption-Assisted Photocatalytic Degradation of Anionic Direct Yellow-50 and Cationic Methylene Blue Dyes by Chemically Synthesized Poly(1,5-Diaminoanthraquinone(Springer, 2025-01-16) Akıllı, A.; Özler, A.; Taymaz, B.H.; Hancı, A.; Eskizeybek, V.; Kamış, H.Conducting polymers renowned for their exceptional photocatalytic activity, conductivity, and visible-light absorption capabilities present a compelling alternative for advanced photocatalytic applications. In this regard, the creation of conductive polymers of the next generation has enormous promise for improving energy efficiency as well as solving environmental issues. In this study, the conductive polymer poly(1,5-diaminoanthraquinone) (PDAAQ) with a band gap of 1.28 eV and an electrical conductivity of 1.23 S/cm was successfully synthesized via chemical oxidative polymerization using ammonium peroxydisulfate as an oxidant and perchloric acid as an initiator in an acetonitrile polymerization medium. The adsorption-assisted photocatalytic performance of PDAAQ has been investigated in cationic methylene blue (MB) and an anionic direct yellow (DY) dye under visible irradiation. The effect of polymerization medium, oxidant type, polymerization time, and monomer oxidant ratio on adsorption-assisted photocatalytic degradation of MB was investigated. The synthesized PDAAQ polymer demonstrates exceptional photocatalytic performance, completely degrading MB and DYE dyes under visible light illumination in 6 and 8 min through an adsorption-assisted photocatalysis mechanism. Besides, the photocatalytic dye degradation performance of PDAAQ was investigated for the degradation of synthetic wastewater (SWW) under visible light. The PDAAQ polymer proves to be an effective photocatalyst for photocatalytic applications, showcasing exceptional potential in degrading model dyes and treating synthetic wastewater. © The Author(s) 2025.Other Aloe Vera Extract-Assisted Hydrothermal Synthesis of CuO Nanoparticles for Photocatalytic Degradation of Methylene Blue Dye(2024) Kamış, Handan; Özler, Ayşenur; Taymaz, Bircan Haspulat; Yaman, Rıza Turgut; Akıllı, AleynaArticle Citation - WoS: 3Citation - Scopus: 4Magnetic and Visible Light-Induced Novel Green Synthesized Magnetic Co3o4 Photocatalysts Via Sunflower Seed Meal Extract for Anionic and Cationic Dye Removal by Adsorption Assisted Photocatalytic Degradation(Taylor and Francis Ltd., 2024-10-18) Akıllı, A.; Haspulat, Taymaz, B.; Özler, A.; Ak, H.; Hancı, A.; Kamış, H.; Taymaz, Bircan Haspulat; Haspulat Taymaz, BircanThis study was aimed at the preparation of m-Co3O4 NPs (magnetic Co3O4 nanoparticles) from sunflower seed meal (SFSM) which is the waste of sunflower seed oil factories, and their application as a photocatalyst for the adsorption assistant photocatalysis degradation of methylene blue (MB), and direct yellow-50 (DY-50) under the visible irradiations. Also, the photocatalytic performance of m-Co3O4 NPs was evaluated in synthetic wastewater. The produced m-Co3O4 NPs were ferromagnetic with a saturation magnetization value of 4.3 emu g−1 and the degradation of cationic MB and anionic DY-50 dyes by 100% and 93% in 20 min and 35 min, respectively, by adsorption-assisted photocatalytic process under visible light was achieved. The reactions were found to be pseudo-second-order equation for the adsorption-assisted photocatalytic process for both dyes. The photocatalytic activity of m-Co3O4 NPs decreased slightly even after five repeated cycles. These results show that the m-Co3O4 NPs can be used successfully in dye treatment in wastewater with their adsorption-assisted photocatalytic properties, activation by visible light, magnetic separability, and low-cost production. © 2024 Taylor & Francis Group, LLC.Article Citation - WoS: 3Citation - Scopus: 3Enhanced Performance of Mxene-Based Supercapacitor Via New Activated Carbon-Nafion Composite Cathode(Pergamon-elsevier Science Ltd, 2025-04-01) Akilli, Aleyna; Taymaz, Bircan Haspulat; Eskizeybek, Volkan; Kamis, HandanAsymmetric supercapacitors leverage differences in the work functions of electrode materials to achieve an extended operating potential window and enhanced energy storage capacity. In this study, an asymmetric supercapacitor was developed using Ti3C2Tx MXene as the working electrode and a composite of activated carbon-nafion (AC-N) and activated carbon-polyvinylidene fluoride (AC-P) as the counter electrode. The work functions of MXene and AC-N were measured as 7.06 and 9.6 eV, respectively, enabling a potential window expansion to 2 V with the AC-N counter electrode. Electrochemical evaluations in H2SO4, MgSO4, and KOH electrolytes revealed specific capacitance values of 555, 367.5, and 425 F g-1 in, respectively. Additionally, corresponding power densities reached 1023, 999.86, and 1980.25 W kg- 1 , while energy densities were determined to be 81.2, 40.55, and 26 Wh kg- 1 . These findings highlight a straightforward strategy to enhance energy storage performance by leveraging the distinctive properties of MXene.Article Citation - WoS: 21Citation - Scopus: 23Facile and Green Synthesis of Zno Nanoparticles for Effective Photocatalytic Degradation of Organic Dyes and Real Textile Wastewater(Taylor & Francis Inc, 2022-11-28) Haspulat Taymaz, Bircan; Demir, Müslüm; Kamış, Handan; Orhan, Hüseyin; Aydoğan, Zuhal; Akıllı, AleynaRemediation of organic dyes from wastewater in textile industries is a big challenge to decreasing water pollution. This study was aimed at the preparation of ZnO nanoparticles (NPs) and their application as a photocatalyst for the degradation of methylene blue (MB), sunfix red (SR) and real textile wastewater (RTW) under both UV and visible irradiations. The ZnO NPs were synthesized with a green Thymus vulgaris leaf extract-supported approach following the calcination process. 50 mg L-1 MB and 50 mg L-1 SR dyes were completely photodegrade under UV irradiation after only 20 and 45 minutes, respectively, in the presence of 1.0 mg/mL ZnO NPs. When they are exposed to visible light, the degradation efficiency reached 91 and 75% within 60 and 120 min, respectively. Photocatalytic measurements of RTW depict that 95% (within 60 min under UV illumination) and 79% (within 90 min under visible illumination) were degraded, respectively. The enhanced photodegradation can be attributed to the narrowing of the bandgap of the ZnO NPs, high crystallinity and nearly hexagonal morphology with an average size of 20-30 nm. The present results show that ZnO NPs could potentially be applied for high-efficiency degradation of organic dyes and RTW under both UV and visible light irradiation. Novelty StatementWe report for the first time, Thymus vulgaris leaf extract-assisted synthesis of ZnO nanoparticles (NPs) has been applied as a photocatalytic dye and RTW degradation. Second, our synthesis approach is more facile and simple than the previous method where complex hydrothermal or solvothermal methods have been applied, which leads to a complex preparation procedure. We systematically prepared ZnO materials in taking account into the variable Thymus vulgaris/ZnO precursor ratio, different calcination temperature and time and in detail, their photocatalytic activity has been fully investigated.
