The creation of a novel composite photocatalyst has gained great attention in the field of organic dye remediation. Herein, the PANI/Fe 3 O 4 photocatalyst has been prepared using the chemical oxidative polymerization of aniline. The as-prepared photocatalyst represents a denser and uniform morphology along with strong magnetic properties. The photocatalytic activity of the PANI/Fe 3 O 4 was investigated for the degradation of Malachite Green (MG), Jakazol Kala (JK) and Levafix Red (LR). In the presence of PANI/Fe 3 O 4 composite, the reaction rate constants were found to be 0.1997, 0.0521, and 0.1993 min À 1 for MG, JK and LR, under UV-light irradiation and 0.0522, 0.0491, 0.0544 min À 1 under visible light irradiation, respectively. The nanocomposite can be easily separated from the treated water and reused several times. The suppression of electron recombination, the reduced bandgap and the broad lightharvesting in both UV and visible-light regions contribute to the advanced photocatalytic performance of the PANI/Fe 3 O 4 .

The sustainable energy development of green carbon precursors and inexpensive activating agents has gained great attention with respect to the manufacture of high-performance electrode materials for supercapacitors. Though the most investigated activation agents such as ZnCl 2 and KOH provide porous carbon possessing the high surface area and large charge storage capacity, those activation agents suffer from the use of high dosage utilization and poor carbon production yield. Herein, we report an alternative preparation method for porous carbons using NaOH, K 2 CO 3 , Na 2 CO 3 and Na 2 S 2 O 3 as activating agents, respectively. Activating performances of four pore-forming agents were compared in terms of textural, morphological and electrochemical performance. It was found that the NaOH-activated electrode material (C-NaOH) exhibited a high specific capacitance of 199 F g À 1 at a current density of 0.5 A g À 1 thanks to its large surface area along with large pore volume. In the two-electrode system, the symmetric SC assembled by C-NaOH electrodes delivered an energy density of 4.7 Wh/kg at a power density of 127 W/kg and maintained 3.9 Wh/kg at a power density of 1560 W/kg. Another outcome of this study was that the Na 2 S 2 O 3 -assisted activating agent could introduce heteroatom into the carbon framework, which contributes to pseudocapacitance behavior of electrodes. Overall, the alternative activating strategy could provide a highperformance carbon electrode and may offer a pathway for an advanced energy storage technology.

Covalently Merging Ionic Liquids and Conjugated Polymers: A Molecular Design Strategy for Green Solvent‐Processable Mixed Ion–Electron Conductors Toward High‐Performing Chemical Sensors

Polymeric mixed ionic–electronic conductors hold great potential for advancing high‐performance organic electronics due to their exceptional electrical conductivity achieved through ion–electron coupling. However, the widespread adoption of these conductors faces obstacles due to their reliance on environmentally harmful solvents during processing and the potential performance degradation under various conditions. In this study, a practical solution to these challenges is proposed by incorporating monomers with ionic liquid‐behaving pendant groups into conjugated polymers. The copolymerization of these charged monomers not only improves solubility in environmentally friendly solvents but also imparts long‐term stability against humidity, high temperatures, and mechanical deformation. The immobilized ion species foster highly selective interactions of these polymers with nitrogen dioxide, paving the way for the development of stretchable sensing devices capable of functioning at exceptionally high temperatures.
