This review examines hydrogen energy as a sustainable alternative to fossil fuels, noting its high energy density and zero-emission combustion. The paper addresses the critical issue of hydrogen storage, evaluating techniques such as high-pressure storage, liquefaction, and physisorption, with a focus on carbon nanotubes (CNTs). CNTs, especially multi-walled carbon nanotubes (MWCNTs), are acknowledged for their high surface area, stability, and enhancement of hydrogen storage capacity via functionalization. Despite their promise, issues such as slow kinetics, high production costs, safety concerns, and long-term durability must be resolved. The review concludes by discussing ongoing research aimed at optimizing CNT synthesis, functionalization, and storage systems, positing that advancements in these domains could facilitate CNT-based hydrogen (H2) storage for clean energy applications, including fuel cells and transportation.
本文综述了氢能作为化石燃料的可持续替代品,指出其高能量密度和零排放燃烧。本文讨论了氢储存的关键问题,评估了高压储存、液化和物理吸附等技术,重点介绍了碳纳米管(CNTs)。碳纳米管,尤其是多壁碳纳米管(MWCNTs)因其高表面积、稳定性和通过功能化提高储氢能力而得到公认。尽管前景光明,但动力学慢、生产成本高、安全问题和长期耐用性等问题必须得到解决。本文最后讨论了正在进行的旨在优化碳纳米管合成、功能化和存储系统的研究,并假设这些领域的进步可以促进碳纳米管氢(H2)存储在清洁能源应用中的应用,包括燃料电池和运输。

The chemoenzymatic reactions leverage the enzymes' excellent selectivity alongside the robust reactivity of traditional catalysts, offering numerous advantages such as higher yield, enhanced selectivity, and reduced residue generation. Despite the challenge posed by incompatibility between different classes of catalysts, recent advances in synthetic chemistry and biology provide ample opportunities for cascade transformations using new biocatalysts and innovative strategies. By integrating organocatalysis, electrocatalysis, photocatalysis, and metal catalysis with biocatalysis, this review showcases how diverse catalytic strategies can be synergistically employed to expand reaction scope, overcome traditional limitations, and unlock new possibilities for chemoenzymatic transformations. Novel approaches and trends are also highlighted.

Lignin, one of nature’s promising biopolymers, has been extensively studied for its potential to support the transition to a less fossil-based economy. Despite evidence from both industry and academia on its various applications, the economic feasibility of lignin still requires further research. This review brings an updated overview of lignin supply and recent techno-economic analysis (TEA) of technical lignin applications. With the global production capacity for kraft lignin reaching 112 kt/year in 2023, there is growing interest in assessing the economic viability of lignin-based products. Besides evaluating technical and economic feasibility, the reviewed TEAs identify bottlenecks and help optimise the processes. They define potential actions (e.g., increase capacity, adjust price strategy, and reduction of lignin cost) that could improve the feasibility of the developed lignin applications.
木质素是自然界最有前途的生物聚合物之一,因其支持向较少依赖化石的经济过渡的潜力而受到广泛研究。尽管工业界和学术界对木质素的各种应用都有证据,但木质素的经济可行性仍需要进一步研究。本文综述了木质素供应的最新概况和木质素技术应用的最新技术经济分析(TEA)。随着全球硫酸盐木质素的生产能力在2023年达到12万吨/年,人们对评估木质素基产品的经济可行性越来越感兴趣。除了评估技术和经济可行性外,审查的tea还确定瓶颈并帮助优化流程。他们定义了潜在的行动(例如,增加产能,调整价格策略,降低木质素成本),可以提高木质素应用的可行性。

Waste disposal involves complex social, economic, and environmental factors, making it a multifaceted problem. With advancements in technology and increased environmental awareness, there is a growing emphasis on turning waste into high value-added products. This review takes a system engineering perspective to hierarchically summarize recent research on the design, evaluation, and integration of waste valorization processes. First, it identifies waste-to-energy as a key area in waste valorization, with gasification emerging as a promising thermochemical conversion technology. Second, it underscores the importance of multi-dimensional assessments in evaluating system's feasibility. While techno-economic analysis and life cycle assessment continue to be the main tools, the importance of incorporating social performance into assessment is highlighted. Additionally, this work identifies a clear trend toward integrating renewable energy and carbon-neutral technologies into waste-to-wealth systems. By systematically synthesizing recent research on waste-to-wealth conversion, this review aims to provide valuable insights for achieving sustainable waste valorization.

As industries transition toward sustainability to meet climate change targets, they face the challenge of moving beyond the fossil economy. This article explores the role of dynamic capabilities in fostering eco-innovations, which are critical for firms aiming to navigate and thrive in the postfossil era. Through the orchestration of internal and external resources, firms can create long-term competitive advantages that align with eco-innovation objectives. Using a resource-based perspective, this study analyzes how firms integrate natural resources into their dynamic capability framework, ensuring that these resources are both preserved and utilized effectively. Eco-innovations are positioned as essential drivers for sustainable transformation, demanding a reconfiguration of corporate strategies, resource management, and collaborative networks.

The increasing demand for urban infrastructure has led to a rise in construction and demolition waste (C&DW), posing environmental and economic challenges. Traditional disposal methods contribute to pollution and resource depletion. The circular economy promotes waste reduction, recycling, and reuse, aligning with EU policies. This paper examines the composition of C&DW, current trends in recycling methods, and the challenges associated with C&DW management (C&DWM), focusing on how emerging technologies, such as AI-powered sorting systems and decision-support tools, could enhance efficiency from a future perspective.

Aerogels are intriguing materials with a wide range of potential applications, from medicine to construction. They can be classified into inorganic, organic, carbon, and biopolymer types, and their properties can be enhanced by incorporating advanced materials and nanofillers. Among these, carbon aerogels are distinguished by their unique solid-state architecture, featuring three-dimensional (3D) interconnected networks permeated with air-filled nanopores. These nanopores greatly enhance the structural characteristics at the macroscopic level, merging the inherent qualities of aerogels, such as low density and high porosity, with the unique attributes of their constituent materials. These features make carbon aerogels highly suitable for specialized biomedical applications. This review emphasizes and examines the recent advancements in the preparation of carbon aerogels and their biomedical applications. It concentrates on the development of aerogels through characterization studies of carbon aerogels and concludes with an analysis of the potential and challenges in creating sustainable materials for biomedical use.
气凝胶是一种有趣的材料,具有广泛的潜在应用,从医学到建筑。它们可以分为无机、有机、碳和生物聚合物类型,它们的性能可以通过加入先进材料和纳米填料来增强。其中,碳气凝胶的特点是其独特的固态结构,具有三维(3D)相互连接的网络,渗透着充满空气的纳米孔。这些纳米孔在宏观层面上极大地增强了气凝胶的结构特征,融合了气凝胶固有的低密度和高孔隙率的特性及其组成材料的独特属性。这些特点使得碳气凝胶非常适合专门的生物医学应用。本文综述了近年来碳气凝胶的制备及其在生物医学上的应用。它通过对碳气凝胶的表征研究来关注气凝胶的发展,并分析了创造生物医学用途的可持续材料的潜力和挑战。

Photocatalytic CO2 conversion is a promising method for reducing atmospheric CO2 using solar energy. This review highlights transformative approaches in this field, focusing on the impact of artificial intelligence and computational chemistry. The fundamentals of photocatalytic CO2 conversion, the role of AI in optimizing processes, and the contributions of Density Functional Theory (DFT) to understanding mechanisms and improving catalyst design are discussed. By integrating AI with DFT, synergistic methods that enhance catalyst development and process efficiency are explored. The review also addresses current challenges and future research directions, emphasizing the potential of artificial intelligent and computational chemistry to advance sustainable CO2 conversion technologies.
