“…In Figure c, the polyhedral-wrapped BiOCl is uniformly dispersed within the carbon nanofibers. This unique morphology not only facilitates rapid charge transport but also enhances electrolyte infiltration and active material utilization. − The low-magnification TEM image (Figure e) reveals the intertwined arrangement of the polyhedra and nanofibers. At higher magnification (Figure f), the carbon nanofibers can be observed to pass through the polyhedral carbon.…”

The unique two-dimensional layered structure of BiOCl makes it highly promising for energy storage applications. In this study, we successfully synthesized BiOCl nanoparticles encapsulated in N-doped carbon nanonecklaces (BiOCl NPs/N-CNNs) using well-established electrospinning and solvothermal substitution. As an anode material for lithium-ion batteries, BiOCl NPs/N-CNNs exhibited enhanced rate performance, delivering a capacity of 220.2 mA h g–1 at 8 A g–1. Furthermore, it demonstrated remarkable long cycle stability, retaining a capacity of 200.5 mA h g–1 after 9000 cycles with a discharge rate of 8.0 A g–1. The superior electrochemical performance can be attributed to the stacked layered structure of BiOCl, facilitated by van der Waals force, as well as the ingenious nanonecklace structures. These structures not only provide fast ion diffusion pathways but also enhance electrolyte penetration and offer more active sites for Li+ insertion and extraction. Additionally, the nanonecklace structure prevents the aggregation of nanopolyhedra, promoting the complete reaction of BiOCl with Li+. Moreover, the unique nanopolyhedron structure alleviates the stress caused by the volume expansion of Bi nanoparticles during cycling and reduces the internal resistance of the electrode.

The overexploitation of finite natural resources and anthropogenic pollution pose a threat to economic security and human health. One approach for tackling these challenges is the development of effective, accessible, low-cost, bioderived, and eco-friendly technologies for the recovery of resources from wastewater. Wastewater contains resources of appreciable market value, including metals, pesticides, inorganic nutrients, dyes, and per- and polyfluorinated substances (PFAS). Established technologies, such as low-pressure membranes, biological treatments, and oxidation, are ineffectual, while more intricate technologies such as customized granular activated carbon and anion exchange resins suffer predominantly from high fouling rates and operating costs, which eventually reduce the effectiveness of resource recovery; thus, these limitations motivate the development of experimental technologies. Green, biopolymeric, smart lignin nanoparticles are potential candidates growing in popularity for their effective recovery of resources from wastewater via adsorption, as lignin-based nanoparticles with metal adsorption capacities higher than 40 mg/g have been reported. In addition, employing lignin nanoparticles for this purpose will promote the circular economy of biorefineries and support the sustainable development of nations. Nonetheless, the valorization of lignin through nanotechnology is limited by the inhomogeneity of technical lignins and the resultant nanoparticles. For instance, the physical (e.g., surface area and electrostatic charge) and chemical (e.g., concentration of hydroxyl and carbonyl groups) properties of the lignin precursor will determine the affinity of the resultant nanoparticles to specific metal ions and their adsorption capacity. Hence, a profound understanding of the relationship between lignin derivation and nanoparticle synthetic methodology with resultant nanoparticle properties (e.g., hydrodynamic size) and performance (i.e., adsorption capacity) is needed to advance the adoption of lignin nanoparticles in sustainable industrial wastewater treatment. Alas, reviews of this nature are lacking. To fill this gap, this perspective reflects on the state-of-the art techniques for lignin nanoparticle synthesis and their application in the retrieval of various substances from aqueous environments, highlighting the properties–performance correlations, the specificity of the nanoparticles, and their comparative performance against established and laboratory-scale technologies. Ultimately, standardized strategies will be needed to control the functionality of lignin nanoparticles (e.g., hydrodynamic size and programmable morphology) to enhance the effective recovery of valuable resources from copious and diverse wastewater resources.

With the serious impact of fossil fuels on the environment and the rapid development of the global economy, the development of clean and usable energy storage devices has become one of the most important themes of sustainable development in the world today. Supercapacitors, known as ultracapacitors, have been supposed to be one of the most promising candidates to meet the requirements of human sustainable development, due to their advantages such as high capacity, high power density, high charging/discharging speed, long cycle life, and low processing cost. However, the low energy density of supercapacitors limits their large-scale application. Therefore, it is of great significance to develop high energy density supercapacitors and use them as power sources for practical devices. Conductive polymer-based electrode materials have unique advantages such as high theoretical capacitance, good conductivity, and good flexibility, and have high potential in supercapacitors. The research on conductive polymer-based electrode materials has promoted the rapid development of the field of supercapacitors. This review summarizes recent research progress on conductive polymers (including polypyrrole, polyaniline, and polythiophene), conductive polymer-based binary composites, and conductive polymer-based ternary and quaternary composites for supercapacitor electrodes. Furthermore, a summary of the use of conductive polymer-based textiles and fibers for flexible supercapacitors is also presented, along with the current challenges and future perspectives for conductive polymer-based supercapacitors.
