However, controlling the structure of hard carbon so that it has a high energy density, favorable rate performance, and cycling stability is still a challenge. We propose a strategy to control the open pore structure of hard carbon derived from wood for sodiumion storage by the addition of sodium carbonate under carbonization at 1100 °C. The resulting HC has an increased interlayer spacing, and a more uniform open pore distribution (2–3 nm) with a high slope capacity, thereby enabling efficient sodium-ion transport and storage. The HC anode has a reversible capacity of 326 mAh g⁻¹ at a current density of 30 mA g⁻¹, and maintains a reversible capacity of 270 mAh g⁻¹ at 1 A g⁻¹ and a capacity of 68 mAh g⁻¹ even at 10 A g⁻¹ during rate performance tests. After 300 cycles, it retains 76.7% (207 mAh g⁻¹) of its capacity at 1.0 A g⁻¹. In situ Raman spectroscopy and the galvanostatic intermittent titration testing results reveal an adsorption-intercalation-filling sodium storage mechanism.

We have prepared free-standing buckypaper films (BPFP) decorated with Fe₃O₄ particles and polyaniline (PANI) by a simple two-step method to meet this requirement. First, buckypaper films decorated with Fe₃O₄ (BPF) were synthesized by the coprecipitation of Fe²⁺/Fe³⁺ ions on buckypaper (BP) which was then coated with a polyaniline layer by the in situ polymerization of aniline monomers. Magnetic characterization revealed that the BPF and BPFP films had saturation magnetization (<em>M</em>_s) values of 14.3 emu g⁻¹ and 13.0 emu g⁻¹, respectively, confirming retention of the magnetic phase. The addition of Fe₃O₄ nanoparticles and polyaniline to BP (30 μm) increased both the magnetic and dielectric losses due to the increased interfacial polarizations and anisotropy energy. 41 μm-thick BPF and BPFP films had an absorption-dominated shielding effectiveness of 35.1 dB and 36.4 dB, respectively, across the 5.85-18 GHz frequency band. These values are respectively 12.9% and 17.0% greater than that of pristine BP, highlighting the positive effect of Fe₃O₄-PANI heterostructures on electromagnetic wave dissipation. These films also had the tensile strength, flexibility, and lightness of BP, demonstrating exceptional promise for next-generation electromagnetic shielding materials.\u0000\t\t\t\t<span><figure><span><img><ol><li><span><span>Download: <span>Download high-res image (175KB)</span></span></span></li><li><span><span>Download: <span>Download full-size image</span></span></span></li></ol></span></figure></span></div></div>","PeriodicalId":19719,"journal":{"name":"New Carbon Materials","volume":"41 3","pages":"Pages 583-595"},"PeriodicalIF":7.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148529437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report a strategy that enables CH₄ formation on cobalt phthalocyanine (CoPc) by regulating the local reaction microenvironment through the catalyst structure. Ultrathin hollow carbon nanospheres (HCNs) with a uniform size were synthesized and used as supports for CoPc, forming “Janus carbon shells” with inner–outer functional asymmetry. The resulting CoPc-HCN hybrid had a maximum CO₂-to-CH₄ selectivity of 15.1%, overcoming the conventional CO-selective behavior of CoPc. Mechanistic studies show that the hollow carbon structure induces a proton enrichment outside the shell through an inner–outer surface interaction. The inner carbon surface promotes the hydrogen evolution reaction (HER) and produces a proton-enriched environment near the CoPc-active outer surface, thereby enabling CO₂ methanation.

The ablation resistance of the composites was evaluated by testing in a dual-pulse solid rocket motor, and their ablation behavior was investigated. The carbon rods formed by twisting and carbonizing fiber bundles, exhibited a hexagonal cross-section, surrounded by a dense PyC “wall” structure formed during the CVI process. The linear ablation rates of the composites after pulse I and pulse II were 0.068 mm/s and 0.113 mm/s, respectively. A cellular-like PyC layer and nanowire structures were deposited on the surface of the throat convergent section during the post-combustion cooling phase, while cracks and delamination occurred on and within the divergent section. The ablation of C/C composites under these conditions was a complex multi-mechanism process, including ultra-high temperatures, high-speed gas scouring, oxygen-containing thermochemical ablation, and thermal shock.

A comprehensive analysis of recent advances in the characterization and application of these materials, is provided, emphasizing their distinct production methods, physicochemical properties, and functional versatility. Biochar, typically obtained by pyrolysis at high temperatures, has a high porosity, aromaticity, and thermal stability, making it well-suited for applications such as CO2 capture, electrochemical energy storage, catalysis, and soil improvement. In contrast, hydrochar, produced by hydrothermal carbonization in aqueous media at moderate temperatures, retains a higher number of surface functional groups and heteroatoms, offering advantages in aqueous-phase catalysis, pollutant adsorption, and bioremediation. The critical role of physicochemical characterization in optimizing material performance is outlined, and analytical techniques including liquid nitrogen adsorption, scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Raman spectroscopy, infrared spectroscopy, Boehm titration, and thermogravimetric analysis are discussed. These show how physical-chemical characteristics such as surface area, functional group chemistry, and degree of graphitization, govern the materials’ suitability for specific applications. Emerging uses in waste water treatment, biofuel production, animal feed, and advanced oxidation processes are examined, alongside their relevance to multiple UN Sustainable Development Goals, particularly in climate action, clean energy, and responsible production. The materials are versatile and can be produced on a large scale. Their performance can be fine-tuned using different production and post-treatment processes, making them key enablers in the transition to a circular, carbon-conscious economy.<span><figure><span><img><ol><li><span><span>Download: <span>Download high-res image (316KB)</span></span></span></li><li><span><span>Download: <span>Download full-size image</span></span></span></li></ol></span></figure></span></div></div>","PeriodicalId":19719,"journal":{"name":"New Carbon Materials","volume":"41 2","pages":"Pages 276-298"},"PeriodicalIF":5.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147753975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fe–Ni nanoparticles were loaded onto the coal tar pitch-based ACF through a simple hydrothermal–calcination method. The results showed that the coal tar pitch-based ACFs had a high specific surface area (1847 m2/g) and a unique microporous structure, and the metals were loaded onto them.

To address this, we synthesized composites of bismuth nanoparticles in N-doped carbon (Bi@NC) by a hightemperature sintering method.

Nevertheless, electrolyte decomposition at the anode surface, especially at 65 °C, leads to uncontrolled SEI growth. We have designed a hybrid negative electrode by incorporating hard carbon (HC) into graphite to increase the surface work function, which effectively hinders electron escape, thereby reducing electrolyte reduction and inhibiting thick SEI formation at 65 °C. The disordered structure of HC faciitates lithium-ion diffusion and prevents lithium plating on the electrode surface. As a result, a hybrid negative electrode containing 50% HC has an especially high capacity (98 mAh/g) at 8 C and long cycle life at 0.5 C at room temperature. Furthermore, in a full battery it has an excellent capacity (128.54 mAh/g) and stable floating charge for 144 h at 65 °C. The electrode achieves a balance between high energy density and high-power density for lithium-ion batteries, thus maintaining stability even during a floating charge at a temperature of 65 °C. This is attributed to the formation of a thinner and more robust SEI.
