Herein, an amide-containing benzoxazine-based PCMs (AMBZ-PCMs) was engineered through benzoxazine chemistry and bio-based materials, achieving tunable phase-change properties while balancing energy density and fire safety. AMBZ-PCMs integrate long alkyl chains with improved phase-change performance, amide-derived reversible hydrogen bonds, and oxazine rings with latent flame retardancy. Upon heating or flame exposure, these materials undergo ring-opening polymerization, forming cross-linked, easily-carbonized networks that suppress combustion without compromising phase-change performance. Representatively, 18-am-18 exhibits a melting temperature of 95.9 °C, enthalpy of 160.5 J/g, and excellent flame resistance (peak heat release rate: 274.1 J/g), outperforming conventional methods through chemically grafting or physically blending flame-retardant components. In addition, the phase transition behavior remained almost unchanged after 50 cycles, confirming the excellent hydrogen-bond reversibility. Practical applications in photothermal drying and automotive thermal management demonstrate the viability of 18-am-18. This strategy based on engineering bio-based benzoxazine molecular provides a feasible solution to fills the gap for high-performance PCMs (80-100 °C).

The CuO-based NH3-SCO catalyst has attracted significant research interest owing to its advantages in catalytic performance and cost, but it is still elusive how support material affects product selectivity, hindering the development of highly N2-selective catalysts. Herein, we present a combined experimental and theoretical study using CuO/MOx (M = Ti, Zr, and Ce) catalysts with different metal oxide supports to provide molecular-level understanding of support effects in NH3-SCO. In situ spectroscopy and theoretical calculations revealed that variations in N2 selectivity of these catalysts originated from their diverse preferences to competing reaction pathways. It was observed that the local coordination environments of the CuOx active sites were tuned by the support material. This active site–support interaction could alter the energy barriers of key elementary reactions (N2H4* formation and NH2* dehydrogenation), resulting in different product selectivity. Scaling relationships between the energy barriers of these key elementary reactions and two easily computed descriptors (the binding strength of key intermediates or reaction energies) were discovered, which could avoid the time-consuming process of transition state searching and enable rational design and fast screening of highly N2-selective NH3-SCO catalysts.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"45 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144164903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conceiving novel stable nitrogen–oxygen compounds remains a formidable challenge for current experimental and theoretical research. In this study, we developed a sequential construction strategy to design 168 nitrogen–oxygen compounds with distinct structural innovation, followed by high-throughput quantum mechanical calculations with the highest possible accuracy. From the resulting 7820 structural and property parameters, we created a customized machine learning model that outperforms universal models in accuracy with 13.8% greater robustness across various data splits, achieving stable and high performance on small datasets. Data-driven analysis revealed the energy and electron-related characteristics as key factors in regulating thermodynamic stability, while physics-driven insights uncovered that electron delocalization and hyperstatic constraints fine-tune mechanical firmness. Among the designed nitrogen–oxygen compounds, 106 are expected to be more stable than the known compound N2O4, out of which 61 are expected to be even more stable than N2O5. Furthermore, their energy densities surpass those of all currently used nitrogen–oxygen oxidizers by 8.3–16.8%, highlighting our newly proposed compounds potential for use in rocket bipropellant systems.

Unlike known (oxy-)hydroxides, this oxy-hydroxide displays exceptional thermal stability, retaining hydroxide ions within its crystal structure up to approximately 700 °C.

To address this global challenge, carbon capture technology has been proposed as a key measure to reduce CO2 concentration in the atmosphere. In this paper, we review recent research advances in carbon capture technologies, with special emphasis on the potential of adsorption technologies to improve efficiency and reduce energy consumption. We discuss in detail the innovations of material systems such as metal-organic frameworks (MOFs), porous organic polymers (POPs), porous carbon-based materials, functionalized adsorbents, and ionic liquids in the field of carbon capture and conversion. Meanwhile, this paper also examines the research progress of solid waste-derived carbon capture materials, such as refinery slag, biomass, natural mineral materials and lignin, from the perspective of solid waste resourcing, which provides new ideas for the sustainable utilization of carbon capture materials. This paper further discusses the preparation methods, recycling performance and regeneration technologies of adsorbents, as well as the mechanisms and processes of physical adsorption and chemical adsorption in carbon dioxide capture. In particular, the potential and challenges of processes such as pressure-variable adsorption (PSA) and temperature-variable adsorption (TSA) for industrial applications are pointed out. The review aims to provide a theoretical basis for the research of carbon capture materials and a reference for practical applications, emphasizing the important role of carbon capture and utilization technologies in promoting low-carbon development and mitigating global warming. With the continuous advancement of technology, we expect that these research results will provide strong support for the realization of global climate goals.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"19 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144164954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
