“…The synthesis of graphene from renewable and abundant biomass feedstocks using simple pyrolysis reactions has therefore been proposed and is regarded as a promising route, especially considering the unique polymeric structure of lignin, which is comprised of aromatic rings and condensed linkages and shows great similarity to the hexagonal structure of graphene, which makes it an excellent precursor for producing graphene and graphene‐like materials . Some valuable studies on graphene and graphene‐like carbon materials derived from biomass lignin have been reported . As shown in Fig.…”

“…There are three typical synthesis routes from lignin to graphene, including: (i) Catalytic graphitization with transitional metals/metal salt catalysts; (ii) direct carbonization in an inert atmosphere; and (iii) a two‐step route involving oxidative cleavage and aromatic refusion . Among these, catalytic graphitization is the most widely used synthesis route for lignin‐derived graphene materials.…”

“…It has also been reported that graphene‐encapsulated metal nanoparticles have been fabricated from lignin through a thermal treatment process under an argon atmosphere with Ni, Cu, Fe, and Mo catalysts . Small graphitic domains with well‐developed graphene layers and a high surface area of 207.5 m 2 g −1 , and 3D graphene and graphene‐like porous carbon were synthesized by the direct carbonization of lignin at a high temperature of 1300 °C . The graphene materials fabricated from lignin by hydrothermal reaction and other supporting steps exhibited a glass‐like microcrystal structure that was chemically bonded by sp carbon atoms .…”

“…The direct carbonization and hydrothermal‐involved processes have both been considered to involve the breaking and recombination of chemical bonds inside lignin molecules under specific conditions . For example, the benzene rings from the pyrolysis of lignin at high temperature are reportedly composed of graphene sheets, and the sp free carbon atoms joined the graphene sheets with chemical bonds along the framework of the lignin polymer . However, all the proposed mechanisms above are based on ex situ composition results from X‐ray diffraction (XRD), Raman, Thermogravity analysis (TGA), Fourier transform infrared (FTIR) and transmission electron microscopy (TEM) characterizations.…”

“…In addition, lignin polymers with various aromatic structures, distinguished from other biomass components, show considerable structure similarity to the hexagonal honeycomb lattice structures of graphene. Thus, lignin is a very promising renewable resource for engineering production of renewable graphene . However, studies on lignin‐derived graphene and graphene‐like materials are still at the early stage, although they have demonstrated significant potential.…”

Electrode and electrolyte materials with higher performance, longer life, and lower cost need to be developed, given the substantial growing demand for advanced electrochemical energy systems. Lignin, the second most abundant natural polymer, has been successfully demonstrated to be a viable precursor or feedstock for the preparation of high-performance electrochemical energy materials and components such as electrodes, electrolyte additives, membrane separators, and binders. Moreover, techno-economic analyses indicate that it is possible to prepare cost-effective carbon structures from lignin at engineering scale, in contrast with current carbon products. These facts suggest that the scalable conversion of lignin into high-value energy materials will offer a promising pathway to not only promote the utilization and valorization of lignin but also boost the development of advanced electrochemical energy systems. This review examines cutting-edge renewable energy materials derived from various lignin compounds and Review: Lignin to energy materials X Wu et al.their applications in electrochemical energy systems with an emphasis on supercapacitors, rechargeable batteries, and fuel cells. Meanwhile, this review also aims to carve out the critical barriers for lignin-derived high-performance materials for energy applications, and to identify viable approaches for the synthesis of sustainable new energy materials.

Emerging contaminants, such as the hormone 17α‐ethynylestradiol (EE), in aquatic environments pose a serious risk to both human and environmental health, making efficient removal essential. This study evaluated the effectiveness of three‐dimensional porous carbon structures derived from poly(acrylic acid) (PAAc, Carbopol 990) as adsorbents for removing EE from aqueous solutions. Activated carbon materials were prepared using varying ratios of KOH as an activating agent (PAAc:KOH; 1:0 AAC, 1:1 AC1, 1:2 AC2, and 1:3 AC3). Adsorption tests were conducted by adding 10 mg of the adsorbent to 40 mL of an EE solution (100 ppm, 20% acetonitrile in water). Analyses including TGA, XRD, and Raman spectroscopy were performed to evaluate the materials' structural properties and adsorption capacities. Among the materials, AC3 exhibited the highest adsorption capacity for EE (238 mg g−1), followed by AC2 (153 mg g−1) and AC1 (82 mg g−1). The superior efficiency of AC3 can be attributed to its larger surface area and pore volume, enabling greater interaction with EE molecules. These materials demonstrated higher adsorption capacities compared to commercial activated carbons and single‐walled carbon nanotubes. This work opens new possibilities for developing efficient adsorbents, contributing to more effective and sustainable solutions for water purification and environmental protection.
