“…Furthermore, due to its high nitrogen content, poly(ionic liquid) (PIL) as the polymerization product of ionic liquids can serve as the source of nitrogen that endows porous carbons with target N doping; in addition, the PIL can induce the formation of extra porous carbon structures through its catalytic degradation of biomass [28]. In comparison to other types of polymers, PILs can be more thermally stable to secure a high carbonization yield [29,30], can be rich in heteroatoms of different types that can dope carbon products [31,32], and can molecularly disperse the iron precursor to secure uniform formation of Fe 3 C nanoparticles in the porous carbon matrix [33]. To note, the cation-anion pair in PIL is one of the key parameters in creating the tiny pores to accommodate active sites for catalysis [24].…”

Fe3C nanoparticles hold promise as catalysts and nanozymes, but their low activity and complex preparation have hindered their use. Herein, this study presents a synthetic alternative toward efficient, durable, and recyclable, Fe3C-nanoparticle-encapsulated nitrogen-doped hierarchically porous carbon membranes (Fe3C/N–C). By employing a simple one-step synthetic method, we utilized wood as a renewable and environmentally friendly carbon precursor, coupled with poly(ionic liquids) as a nitrogen and iron source. This innovative strategy offers sustainable, high-performance catalysts with improved stability and reusability. The Fe3C/N–C exhibits an outstanding peroxidase-like catalytic activity toward the oxidation of 3,3′,5,5′-tetramethylbenzidine in the presence of hydrogen peroxide, which stems from well-dispersed, small Fe3C nanoparticles jointly with the structurally unique micro-/macroporous N–C membrane. Owing to the remarkable catalytic activity for mimicking peroxidase, an efficient and sensitive colorimetric method for detecting ascorbic acid over a broad concentration range with a low limit of detection (~2.64 µM), as well as superior selectivity, and anti-interference capability has been developed. This study offers a widely adaptable and sustainable way to synthesize an Fe3C/N–C membrane as an easy-to-handle, convenient, and recoverable biomimetic enzyme with excellent catalytic performance, providing a convenient and sensitive colorimetric technique for potential applications in medicine, biosensing, and environmental fields.

The breadth and importance of polymerized ionic liquids (PILs) are steadily expanding, and this review updates advances and trends in syntheses, properties, and applications over the past five to six years. We begin with an historical overview of the genesis and growth of the PIL field as a subset of materials science. The genesis of ionic liquids (ILs) over nano to meso lengthscales exhibiting 0D, 1D, 2D, and 3D topologies defines colloidal ionic liquids, CILs, which compose a subclass of PILs and provide a synthetic bridge between IL monomers (ILMs) and micro to macroscale PIL materials. The second focus of this review addresses design and syntheses of ILMs and their polymerization reactions to yield PILs and PIL-based materials. A burgeoning diversity of ILMs reflects increasing use of nonimidazolium nuclei and an expanding use of step-growth chemistries in synthesizing PIL materials. Radical chain polymerization remains a primary method of making PILs and reflects an increasing use of controlled polymerization methods.Step-growth chemistries used in creating some CILs utilize extensive cross-linking. This cross-linking is enabled by incorporating reactive functionalities in CILs and PILs, and some of these CILs and PILs may be viewed as exotic cross-linking agents. The third part of this update focuses upon some advances in key properties, including molecular weight, thermal properties, rheology, ion transport, self-healing, and stimuli-responsiveness. Glass transitions, critical solution temperatures, and liquidity are key thermal properties that tie to PIL rheology and viscoelasticity. These properties in turn modulate mechanical properties and ion transport, which are foundational in increasing applications of PILs. Cross-linking in gelation and ionogels and reversible step-growth chemistries are essential for self-healing PILs. Stimuli-responsiveness distinguishes PILs from many other classes of polymers, and it emphasizes the importance of segmentally controlling and tuning solvation in CILs and PILs. The fourth part of this review addresses development of applications, and the diverse scope of such applications supports the increasing importance of PILs in materials science. Adhesion applications are supported by ionogel properties, especially crosslinking and solvation tunable interactions with adjacent phases. Antimicrobial and antifouling applications are consequences of the cationic nature of PILs. Similarly, emulsion and dispersion applications rely on tunable solvation of functional groups and on how such groups interact with continuous phases and substrates. Catalysis is another significant application, and this is an historical tie between ILs and PILs. This component also provides a connection to diverse and porous carbon phases templated by PILs that are catalysts or serve as supports for catalysts. Devices, including sensors and actuators, also rely on solvation tuning and stimuliresponsiveness that include photo and electrochemical stimuli. We conclude our view of applications with 3D printi...

The natural biological water system has been seriously damaged due to the discharge of wastewater containing too much molybdenum, endangering the life and health of animals and plants. Imidazolium‐based poly (ionic liquid) was synthesized by grafting copolymers of styrene and 1‐(chloromethyl)‐4‐vinylbenzene into N‐methylimidazole, N‐ethylimidazole and N‐propyl imidazole, followed by characterization with the use of nuclear magnetic resonance spectrometer and Fourier transform infrared spectrometer. How the Imidazolium‐based poly (ionic liquid) could recover MoO42− from sewage was investigated. The pH, reaction temperature, reaction duration, adsorbent dose, and interfering ions were all tuned for MoO42− adsorption conditions. Nitric acid can regenerate the Imidazolium‐based poly (ionic liquid) loaded with MoO42−. Both the adsorption kinetics and the adsorption isotherm exhibit good agreement with the quasi second‐order kinetic model and the Langmuir isotherm model, respectively.Imidazolium‐based poly (ionic liquid) have a special reusability when compared to polyaniline‐modified bentonite, iron‐based nanomaterials, and γ‐Fe2O3 nanomaterials. The results reveal that Imidazolium‐based poly (ionic liquid) has a strong recovery effect on trace molybdenum from wastewater, which makes it an effective adsorbent with industrial application value.
