Biomass, heralded as sustainable “green coal”, plays a crucial role in energy conservation and achieving “dual carbon” objectives through clean conversion. This paper reviews advancements in biomass catalytic gasification, a technology pivotal for converting biomass to hydrogen-rich fuel and syngas. It highlights the efficiency gains afforded by various catalysts, including natural minerals, alkali metals, nickel-based compounds, zeolites, and rare earth-modified composites. The focus is on their influence on hydrogen output, syngas quality, and tar reduction. The synthesis of these insights paves the way for novel catalyst development and optimized gasification processes, hence advancing catalytic gasification technology toward more sustainable energy solutions.

Lithium-sulfur (Li-S) batteries are one of the most promising energy storage and conversion devices due to the high theoretical capacity and cost-effectiveness of sulfur. However, they still suffer from sluggish redox kinetics and the shuttle effect caused by complex polysulfides. In this work, graphitic carbon nitride (g-C3N4) is utilized as a template and further hydrothermally treated with an Mn source and glucose. The pyrolysis of g-C3N4 gives rise to N-doped carbon nanotubes, producing abundant sites for physical confinement and chemical adsorption of polysulfides, while glucose carbonization brings forth amorphous carbon and Mn source produces metal spheres. Afterward, polydopamine (PDA) induces N-doped carbon coating and promotes interface connection as well as electron immigration. This synergistic design possesses a high surface area of micropores and mesopores to aggregate sulfur and accelerate redox kinetics. As a result, the N-doped carbon nanotube with Mn spheres and PDA coating@sulfur (CN/Mn-PDA@S) exhibits a high reversible capacity of 813.5 mAh g−1 at 1 C with a decay rate of 0.064% per cycle and remarkable capacity retention at 2 C with rate performance up to 4 C. Therefore, the novel design of N-doped carbon nanotubes with Mn spheres and PDA coating serves as an efficient polysulfide immobilizer for Li-S batteries.
锂硫电池（li -硫电池）由于其高理论容量和成本效益而成为最有前途的能量存储和转换设备之一。然而，它们仍然受到缓慢的氧化还原动力学和复杂多硫化物引起的穿梭效应的影响。在这项工作中，石墨氮化碳（g-C3N4）被用作模板，并进一步用锰源和葡萄糖进行水热处理。g-C3N4热解生成n掺杂碳纳米管，产生丰富的多硫化物物理约束和化学吸附位点，葡萄糖碳化生成无定形碳，Mn源生成金属球。然后，聚多巴胺（PDA）诱导n掺杂碳涂层，促进界面连接和电子迁移。这种协同设计具有高表面积的微孔和介孔，可以聚集硫并加速氧化还原动力学。结果表明，含有Mn球和PDA涂层的n掺杂碳纳米管coating@sulfur （CN/Mn-PDA@S）在1℃时具有813.5 mAh g−1的高可逆容量，每循环衰减率为0.064%，在2℃时具有显著的容量保持，速率性能高达4℃。因此，这种含有Mn球和PDA涂层的n掺杂碳纳米管可作为Li-S电池的高效多硫化物固定化剂。

Aqueous Zn-based batteries (AZBs) are hindered by issues associated with the Zn electrodeposition process (ZEDP) on electrode surfaces, including passivation, dendrite formation, and hydrogen evolution. One of the important reasons is the drastic fluctuation in the concentration of Zn2+ ions on the electrode surface during the charging and discharging process. In this work, an electrolyte with Zn2+ ion buffer layer (EZIBL) is proposed to regulate the ZEDP. First, numerical simulations and corresponding experiments are conducted to assess the impact of different thicknesses of the Zn2+ ion buffer layer (ZIBL) on the variation in Zn2+ ion concentration, from which the optimal thickness of the ZIBL is determined. Then, the regulation role of EZIBL in the cycling process is demonstrated by a Zn-Cu half cell. Further, combined with the potential profile of the symmetric cell and the experimental phenomena, the regulation role of EZIBL in ZEDP is systematically explained at the mechanistic level through the analysis of key parameters. Finally, a full battery composed of Zn-LiMn2O4 is assembled to evaluate the practical applicability of the EZIBL in real battery cycles, which shows great enhancement in capacity retention and coulombic efficiency. This work proposes the design of the EZIBL used to regulate the ZEDP and provides a simple, low-cost regulation method for the development of high-performance AZBs.

This study investigates the impact of silicon (Si) on the corrosion resistance and post-corrosion toughness of ferrite/martensitic (F/M) steels in a liquid lead-bismuth eutectic (LBE) environment. Corrosion tests were performed on HT-9 and EP-823 (1.17 wt% Si) steels at 550 °C for 1000 h under oxygen-controlled conditions. The resulting oxide layer consisted of an outer magnetite layer, a spinel layer and an inner oxide zone (IOZ). A Si-rich oxide layer was identified within the spinel and IOZ layers of EP-823, which slowed the growth rate of the oxide layer, enhanced antioxidant performance, and inhibited dissolution corrosion by the LBE. Post-corrosion mechanical properties were evaluated using a small punch test. Results showed a significant reduction in HT-9's toughness within 240 h of corrosion, while EP-823 exhibited increased brittleness after 500 h due to Si-promoted carbide and Laves phase precipitation, significantly reducing its toughness.

The pressing environmental concerns and the depletion of fossil fuel reserves necessitate a transition toward sustainable energy sources. Ethanol, a renewable biomass-derived fuel, is a promising alternative due to its availability and high energy density. This study investigates the synthesis of gold nanoparticles (Au NPs) via a square-wave pulse deposition technique, aiming to enhance catalytic activity for ethanol electrooxidation. By varying pulse durations, we were able to exert precise control over Au NP size and distribution without stabilizing agents. Characterization using field emission scanning electron microscopy and X-ray diffraction techniques confirmed the formation of clustered nanoparticles of metallic gold phase. Electrochemical characteristics analyses revealed that Au NPs synthesized with a 900 ms pulse duration exhibited the lowest charge transfer resistance and the highest electrochemically active surface area. The electrocatalytic performance test of these Au NPs demonstrated an anodic current density of 2.5 mA cm−2 and a Tafel slope of 78 mV dec−1, indicating superior catalytic performance and reaction kinetics. Additionally, the Au NPs showed high resistance to poisoning, as evidenced by a low jb/jf ratio of 0.28 and stable chronoamperometric response. These findings underscore the potential of this synthesis method for producing high-performance electrocatalysts utilized in exploiting ethanol's potential as an environmentally friendly energy carrier.

Cobalt-based layered double hydroxides (LDHs) are highly sought after by researchers due to their low-cost, high efficiency and stability for oxygen evolution reaction (OER) in water electrolysis. The OER performance of these LDHs is closely related to their morphology and electronic structure. However, there is a lack of theory on how to control reaction conditions to regulate the morphologies. In this paper, the growth mechanism of LDH prepared in different solvents is thoroughly studied. Consequently, the Co/Ni-LDHs exhibiting a 3D hierarchical flower-like structure were synthesized with normal alcohol as a solvent, meanwhile, the thickness of the LDHs can be controlled by the molecular weight of the normal alcohol. By adjusting the suitable Co/Ni ratio and solvent, the Co/Ni0.050-LDH-Me was synthesized and exhibited excellent OER performance. At 10 mA cm−2, the overpotential of Co/Ni0.050-LDH-Me is 307 mV, and the Tafel slope is 76.5 mV dec−1.
钴基层状双氢氧化物（LDHs）因其低成本、高效和稳定的析氧反应（OER）而受到研究人员的广泛关注。这些低密度聚合物的OER性能与其形貌和电子结构密切相关。然而，如何通过控制反应条件来调控其形貌，目前还缺乏理论依据。本文对LDH在不同溶剂中的生长机理进行了深入的研究。因此，以正醇为溶剂合成了具有三维分层花状结构的Co/Ni-LDHs，其厚度可由正醇的分子量控制。通过调整合适的Co/Ni比和溶剂，合成了Co/Ni0.050-LDH-Me，并取得了优异的OER性能。在10 mA cm−2时，Co/Ni0.050-LDH-Me过电位为307 mV， Tafel斜率为76.5 mV / dec−1。

Zn anode-based electrochromic devices (ZECDs) stand out as a highly promising technology in the upcoming era of multifunctional electronic devices, offering a blend of electrochromic capabilities and energy storage functions within a single transparent platform. However, significant challenges persist in achieving efficient patterning, ensuring long-term stability, and fast color-switching kinetics for these devices. In this study, heterogeneous tungsten oxide nanowires (W17O47/Na0.1WO3, WNOs) are formulated into inkjet printing ink to assemble patternable ZECDs. The heterogeneous electrode structure of WNO enables a highly capacitive-controlled mechanism that promotes fast electrochromic/electrochemical behavior. Notably, by utilizing a three-dimensional MXene mesh modified substrate, the inkjet-printed ZECDs exhibit a wide optical modulation range of 69.13%, rapid color-changing kinetics (tc = 4.1 s, tb = 5.4 s), and highly reversible capacities of 70 mAh cm−2 over 1000 cycles. This scalable strategy develops the patterned electrodes with a wide optical modulation range and substantial energy storage properties, offering promising prospects for their application in next-generation smart electronics.
