The catalytic steam reforming (SR) of biomass-derived organic compounds could be considered as a promising route to generate H2 fuel. This work aimed to achieve efficient H2 production by the SR of aqueous products obtained from the hydrothermal conversion process of lignocellulosic biomass. The catalytic SR was studied over 15Ni/NiAl2O4 for model compound mixtures composed of furfural, levulinic acid, and formic acid. At a reaction temperature of 800 °C, the high H2 yield of 93.8 % was achieved. Bimetallic Ni–Cu and Ni–Co catalysts supported by NiAl2O4 were synthesized to optimize the SR performance in the presence of H2SO4 as impurity. The Ni–Co and Cu–Ni alloys formed on the bimetallic catalysts during calcination and reduction were verified. The results revealed that the alloys formation improved the resistance of catalysts to oxidation and H2SO4, thus weakening the catalyst deactivation during the SR process. Importantly, the catalytic SR was successfully applied to convert aqueous products from the hydrothermal conversion of pine sawdust. This study provides an encouraging route for upgrading biomass into high-value fuels.

Porous carbons hold broad application prospects in the domains of electrochemical energy storage devices and sensors. In this study, porous carbon derived from sodium alginate-encapsulated ZIF-8 (SA/ZIF-8-C) was successfully prepared by blending ZIF-8 particles with sodium alginate, forming hydrogel beads in the presence of divalent metal ions, and subsequently subjecting them to high-temperature pyrolysis. Various characterization techniques were employed to evaluate the properties of the prepared materials. The introduction of a carbon framework on ZIF-8-derived particles effectively enhanced the conductivity of the prepared materials. The SA/ZIF-8(1.0)-C sample heated at 800 °C exhibited a specific capacitance of up to 208 F g⁻¹ at a current density of 0.5 A g⁻¹ and outstanding cyclic stability. Even after 10,000 charge and discharge cycles, its capacitance retention rate remained as high as 87.14 %. The symmetric supercapacitor constructed with the composite demonstrated an excellent energy density of 14.58 Wh kg⁻¹ at a power capacity of 403.85 W kg⁻¹. The implementation of this study provides new ideas and inspiration for the development of high-performance supercapacitors.

Immobilization of alcalase on a ZIF-L (A@ZIF-L) support was explored for its potential application in producing hydrolysates of proteins extracted from microalgae. The immobilized enzyme was characterized using FTIR, XRD, SEM, and TGA, and the maximum adsorption capacity was found to be 672.1 ± 5.5 mg g⁻¹ at 40 °C. Adsorption equilibrium data indicated that alcalase physically adsorbed onto the ZIF-L, with the isotherm well described by the Freundlich model. The adsorption kinetics aligned best with the pseudo-first order model, suggesting that both film and intraparticle diffusion were significant. The hydrolytic activity of the immobilized A@ZIF-L was initially tested using BSA as a substrate. A diffusion-reaction model was developed and numerically solved to describe the reaction, with results confirming the presence of mass transfer limitations in the early stages of hydrolysis. The stability of the immobilized enzyme was demonstrated by retaining over 90 % of its initial activity after being stored at 4 °C for 70 days. Furthermore, the immobilized A@ZIF-L was used to hydrolyze protein extracts derived from Scenedesmus sp. microalgae. The bioactivity of the resulting protein hydrolysates was characterized, showing a total phenolic content of 29.1 ± 0.6 mg GAE g⁻¹ and a radical scavenging activity of 82.75 ± 2.20 %. These findings highlight the potential of Alcalase-based biocatalysts for applications in the food industry.

Oxygen-rich porous carbons are promising candidates for the carbon-based cathodes of zinc ion hybrid capacitors (ZIHCs). Potassium activation is a traditional and effective way to prepare oxygen-rich porous carbons. Efficient potassium activation is the key to develop high-performance oxygen-rich porous carbon cathodes. Herein, the alkali lignin, extracted from eucalyptus wood by geopolymer-assisted low-alkali pretreatment, is used to prepare oxygen-rich lignin-derived porous carbons (OLPCs) through KOH activation and K2CO3 activation at 700–900 °C. KOH activation constructs a hierarchical micro-mesoporous structure, while K2CO3 activation constructs a microporous structure. Furthermore, K2CO3 activation could more efficiently construct active oxygen (C = O) species than KOH activation. The OLPCs prepared by KOH/K2CO3 activations at 800 °C show the highest microporosity (78.4/87.7 %) and C = O content (5.3/8.0 at.%). Due to that C = O and micropore adsorb zinc ions, the OLPCs prepared by K2CO3 activation at 800 °C with higher C = O content and microporosity deliver superior capacitive performance (256 F g-1 at 0.1 A g-1) than that by KOH activation at 800 °C (224 F g-1 at 0.1 A g-1), and excellent cycling stability. This work provides a new insight into the sustainable preparation of oxygen-rich porous carbon cathodes through efficient potassium activation for ZIHCs.
富氧多孔碳是锌离子杂化电容器（zihc）碳基阴极的理想材料。钾活化是制备富氧多孔碳的一种传统而有效的方法。高效的钾活化是开发高性能富氧多孔碳阴极的关键。本文以桉木为原料，采用地聚合物辅助低碱预处理提取碱木质素，在700 ~ 900℃下经KOH活化和K2CO3活化制备富氧木质素衍生多孔碳（OLPCs）。KOH活化构建层次微介孔结构，K2CO3活化构建微孔结构。此外，K2CO3活化比KOH活化能更有效地构建活性氧（C = O）。在800℃下KOH/K2CO3活化制备的olpc具有最高的微孔隙率（78.4/ 87.7%）和C = O含量（5.3/8.0 at.%）。由于C = O和微孔吸附锌离子，800℃下K2CO3活化制备的olpc具有较高的C = O含量和微孔率，其电容性能（0.1 A g-1时256 F -1）优于800℃下KOH活化（0.1 A g-1时224 F -1），并且具有良好的循环稳定性。本研究为通过高效钾活化zihc制备富氧多孔碳阴极提供了新的思路。

In this work, we investigate how activated carbon (AC) derived from olive pomace biomass can be used as an anode material in lithium-ion batteries. The biomass-derived activated carbon has the potential to be highly efficient, deliver high performance, sustainable, and cost-effective in LIBs-related production. The activated carbon is prepared by using H3PO4 as a chemical activation agent, and then calcining the obtained product at 500 °C for different controlled atmospheres under (i) air (AC-Atm), (ii) vacuum (AC-Vac), and (iii) argon (AC-Arg). The different samples were systematically analyzed using scanning electron microscopy (SEM), High-resolution transmission electron microscopy (HRTEM), energy dispersive spectroscopy (EDS), X-ray fluorescence (XRF), X-ray diffraction (XRD), FT-IR and Raman spectroscopy, and thermogravimetric analysis (TGA) to assess their properties. The electrochemical properties of the carbonaceous materials were studied by galvanostatic cycling, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). The results showed high specific capacity and stable cycling performance, with capacities of 288, 184, and 56 mAh g-1 at the current density of 25 mA g-1 after 70 cycles for AC-Arg, AC-Vac, and AC-Atm respectively. Furthermore, the CE efficiency was nearly 100% from the first cycles. This study opens up interesting prospects and offers promising opportunities for more efficient recovery of unused olive pomace waste, by integrating it into energy storage applications, particularly sustainable lithium-ion batteries.

Hexavalent chromium, when present in high concentrations, causes a serious threat to the ecosystem. This can lead to severe ecological damage and persistent environmental issues, making it a significant concern for long-term sustainability. Thus, there is a strong need for high-performing adsorbents to remove high concentrations of Cr (VI) from the environment. In the present study, Citrus Limetta peels were utilised to produce pristine biochar, which was treated with iron oxides to generate magnetic biochar and modified with chitosan, sodium alginate, and pectin to produce respective modified biochar. Among all five biochars, Chitosan-modified biochar (CMBC) displayed the highest removal efficiency towards Cr (VI) from water with a maximum adsorption capacity of 152.44 mg/g and a removal capacity of 76.22 %. Furthermore, adsorption kinetics indicates that the adsorption process is a pseudo-second order-kinetic model with R2 and qe of 0.99 and 99 mg/g, respectively. The Langmuir isotherm best describes the adsorption process. After five regenerative cycles, the removal efficiency was maintained at up to 71.80 %. This work highlights the remarkable potential of engineered biochar in wastewater treatment.

This can lead to severe ecological damage and persistent environmental issues, making it a significant concern for long-term sustainability. Thus, there is a strong need for high-performing adsorbents to remove high concentrations of Cr (VI) from the environment. In the present study, Citrus Limetta peels were utilised to produce pristine biochar, which was treated with iron oxides to generate magnetic biochar and modified with chitosan, sodium alginate, and pectin to produce respective modified biochar. Among all five biochars, Chitosan-modified biochar (CMBC) displayed the highest removal efficiency towards Cr (VI) from water with a maximum adsorption capacity of 152.44 mg/g and a removal capacity of 76.22 %. Furthermore, adsorption kinetics indicates that the adsorption process is a pseudo-second order-kinetic model with R<sup>2</sup> and q<sub>e</sub> of 0.99 and 99 mg/g, respectively. The Langmuir isotherm best describes the adsorption process. After five regenerative cycles, the removal efficiency was maintained at up to 71.80 %.

As a significant branch of smart materials, self-healing polyurethane materials mimic the biological damage repair mechanisms and have been widely applied in flexible electronics, functional coatings, biomedicine, and other fields. This review systematically summarizes the design principles and recent advancements in both extrinsic and intrinsic self-healing polyurethane materials, highlighting their respective self-healing mechanisms and characteristics. For extrinsic system, damage repair is primarily achieved through microcapsules, hollow fibers, nanoparticles, and microvascular networks. However, their healing efficiency remains limited by the stability of carriers and the release kinetics of healing agents. In contrast, intrinsic self-healing polyurethane materials achieve self-healing through the reversibility of dynamic covalent and non-covalent bonds, which confer excellent self-healing capabilities while necessitating a precise balance between mechanical performance and self-healing efficiency. Moreover, their healing behavior is highly dependent on environmental conditions, potentially restricting their practical applications. Recent studies have demonstrated that the synergistic design of dynamic bonding networks can significantly enhance the mechanical properties, self-healing efficiency, and environmental adaptability. These developments offer new insights and theoretical foundations for designing high-performance self-healing polyurethane materials and may broaden their industrial applications.
