Currently, vanadium phosphorus oxide (VPO) is the most widely used catalyst for the selective oxidation of <i>n</i>-butane to MA owing to its abundant active sites and oxygen species. However, the development of efficient VPO catalysts remains urgent, as the MA yield is limited by the inherent “trade-off” effect between <i>n</i>-butane conversion and MA selectivity. This review systematically summarizes the progress in the rational design and precise regulation of VPO catalysts, with a particular focus on the influence of physicochemical properties on catalytic performance. More importantly, advanced synthesis routes and modification strategies are discussed in detail. These strategies for modulating the geometric and electronic structures of VPO catalysts are highlighted, accompanied by a discussion of the structure-activity relationship. Finally, the challenges of VPO catalysts are discussed, and future research directions are proposed.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"19 8","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145165529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By establishing atomically precise arrangements of catalytic centers on metallic surfaces, single-atom alloy create highly efficient active sites with near-perfect atomic utilization. The robust electronic coupling and geometric interactions between the atomic-scale precision sites and the supporting metal matrix impart exceptional catalytic properties, such as improved kinetic performance, precise molecular recognition, and prolonged operational durability. In essence, the structural integrity of the isolated metal active sites in single-atom alloy, combined with their precisely tunable coordination environments, substantially boosts the electrochemical performance and catalytic efficiency. This review begins by introducing and discussing the fundamental concepts and inherent attributes of single-atom alloy. The methodological framework for single-atom alloy development was systematically examined, encompassing architectural design principles, fabrication methodologies, and analytical characterization techniques. Following this, the comprehensive summarization was conducted regarding the implementation of single-atom alloy catalysts in energy transformation technologies, with specific emphasis on fuel cells and environmentally electrochemical processes.

Researchers have recently focused on building hybrid supercapacitors and synthesizing electrode materials using ecological and easily scalable methods. This work presents the development of hybrid supercapacitors based on cobalt ferrite-carbon composite. The spinel ferrite was synthesized by co-precipitation followed by heat treatment, and a ferrite-glucose precursor was used to obtain a mesoporous composite with a specific surface area of 41.195 m²·g⁻¹. Adding carbon does not structurally modify the cobalt ferrite but significantly improves the electrochemical properties. The electrochemical characterization in a three-electrode cell yielded a maximum specific capacitance of 548.1 F·g⁻¹ at a current density of 14.5 A·g⁻¹. The composite was mixed with sustainable activated carbon in different proportions to assemble solid-state hybrid supercapacitors. A maximum specific capacitance and energy of 69.8 F·g⁻¹ and 27.9 Wh·kg⁻¹ were obtained with a symmetric 1.2 V device, corresponding to a specific power of 94 W·kg⁻¹.

This strategy achieves ultrafine nano-fibrillation of cellulose pulp into nanofibers and their simultaneous homogenous distribution in the polyvinyl alcohol matrix, as evidenced by the homogenized structural morphology and enhanced interfacial interactions. With increased grinding degree, the cellulose fibers are gradually exfoliated and uniformly distributed in the polyvinyl alcohol matrix. The structure evolution of polyvinyl alcohol/cellulose composites during exfoliation and the structure-properties relationship are systematically analyzed. Consequently, the resultant polyvinyl alcohol/cellulose nanofibers composite films exhibit a ‘reinforced concrete’ structure with improved grain boundary strengthening effect, stress transfer capability and barrier properties. The elastic modulus, tensile strength and toughness of the polyvinyl alcohol/cellulose nanofibers composite films are significantly enhanced by 195.1%, 33.8% and 56.2% compared to those of pure polyvinyl alcohol film, respectively. The greatly reduced oxygen permeability coefficient demonstrates their great potential in food packaging.

Analysis of optical emission spectra and gas composition under varying flow rates, introduced microwave power, and operating pressures was performed, while specific calculations were applied to support the measurement including electron concentration, electron temperature, and plasma gas temperature. A characteristic curve of carbon dioxide plasma is introduced as a novel outcome, which helps to elucidate the positive impact of applying reduced pressure. 46.4% carbon dioxide conversion efficiency was demonstrated by applying 5 NL·h⁻¹ flow rate, 80 mbar, and with 14.5 MJ·mol⁻¹ molar energy input utilizing only neat carbon dioxide, and achieved with continuous operation, without using any catalyst, in a straight waveguide system.

This review delves the transformation of the chemical industry from traditional digital simulations to advanced AI-based approaches, targeting high efficiency and low carbon emissions across the scale from molecules to factories. Particular emphasis is mainly placed on the research carried out within the research group of Weifeng Shen. At the molecular level, the intelligent capture of molecular characteristics and the precise determination of structure-property relationships have reached a mature stage. Furthermore, multifunction-driven reverse molecular design for solvents, reaction reagents, and other substances has been accomplished through AI-based high-throughput screening and generative models. To improve the safety, environmental friendliness, and carbon reduction performance of chemical separation processes, a series of innovative reinforcement strategies have been put forward, with a primary focus on the systematic optimization of solvent design. On the process scale of actual production, it frequently occurs that the constructed mechanism model fails to align with the actual system behavior, thereby restricting the industrial application of the model. To solve this issue, mechanism-data hybrid-driven frameworks have been successfully developed, leveraging AI-enhanced prediction, diagnosis, optimization, and control for complex separation systems in practice. Finally, as a bridge connecting big data intelligent technology and actual industrial processes, dynamic digital twin modeling is discussed for its potential to boost efficiency and sustainability in the chemical industry.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"19 7","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145168823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
