Over the last few decades, industrialization and urbanization have accelerated environmental degradation and, therefore, require scientific approaches for proper monitoring and management. This review specifically examines biosensors based on nanomaterials and their application in environmental monitoring for sustainable purposes such as detecting heavy metals in water, air-borne pollutants and greenhouse gases, pesticides in soil and foods, identification of biological agents and pathogens. For instance, graphene based immunosensors have shown high level of resistivity and stability, identifying lead ions in water at very low limits of detection, 0.01 ppb. In the same way, biosensors, which contain gold nanoparticles, have shown high sensitivity to the mercury ions; their detection limit reaches 0.005 ppb. This review describes the nanomaterials used in biosensors in terms of their dimensionality and the essential properties of mechanical, thermal, electronic, optical, and catalytic that qualify them for use in biosensors. It also presents the mechanisms of interaction between nanomaterials and biomolecules based on the intended application, and other important factors that need to be considered when designing nanobiomaterials. Furthermore, the review highlights the current issues, limitations, and future prospects of the material in terms of stability, reproducibility, biocompatibility, and environmental concerns, as well as the integration of the material into future smart multi-functional systems such as Internet of Things (IoT), machine learning (ML), and other innovative systems, and issues related to scaling up and commercialization. This systematic literature review shows the potential role of nanomaterial biosensors to enhance the achievement of the sustainable development goals (SDGs) toward a healthier and sustainable society.

Unique features of graphitic carbon nitride (g-C₃N₄, gCN) nanocomposites include exceptional chemical stability, ease of manufacturing and modification, spatially segregated photo-induced charge carriers, and feasible redox properties. As a result, they are attracting unusual attention. In particular, the direct Z-scheme heterojunctions (ZSHJ) constructed with gCN exhibit photocatalytic activity and selectivity with applications in the realms of energy and environment. Advances in the synthesis of gCN-based ZSHJ as well as their photocatalytic applications, with emphasis on the decomposition of contaminants in water, production of H₂ and O₂, and conversion of CO₂ to biofuels and biochemical, were highlighted. Insight was provided on the latest developments in gCN ZS photocatalytic materials with the accompanying challenges including the S-scheme photocatalysis. Thus, an in-depth analysis, the limited light absorption range of g-C₃N₄ and its high rate of charge carrier recombination hinder its efficiency. The structural limitations, including low surface area and insufficient porosity, reduce catalytic activity while ensuring the stability of Z-scheme interfaces and preventing back electron transfer remains complex. Moreover, scaling up production and achieving cost-effective synthesis are ongoing hurdles. Addressing these challenges requires innovations in bandgap engineering, composite formation, and morphology control, along with the development of green and scalable synthesis methods.

This review provides a comprehensive overview of the recent progress in zinc-NO_x (Zn-NO_x) chemistries, focusing on their basic reactions, detection methods for various products, and the development of high-performance electrocatalysts. The electrocatalysts for NO_x reduction in Zn-NO_x batteries are systematically discussed, highlighting their synthesis strategies, structure-activity relationships, and catalytic mechanisms. Key performance metrics, such as ammonia yield, Faradaic efficiency, and power density, are also compared for the most promising electrocatalysts in each category. As such, Zn-NO_x chemistries, where NO_x represents nitrate (NO₃⁻), nitrite (NO₂⁻), or nitric oxide (NO), have emerged as promising systems for electrochemical ammonia production, nitrogen cycle management, and energy storage. Converting NO_x waste into valuable ammonia is crucial for reducing environmental pollution and generating a useful product. Additionally, energy storage is essential for integrating renewable energy sources into the power grid, and Zn-NO_x batteries offer a unique solution to this challenge, paving the way for the practical implementation of Zn-NO_x batteries in sustainable ammonia production and energy storage. The novelty and significance of Zn-NO_x batteries lie in their ability to simultaneously address environmental concerns and energy storage needs, setting them apart from other existing technologies. With continued research efforts and innovations in electrocatalyst design and battery engineering, Zn-NO_x batteries hold great promise for contributing to a more sustainable and energy-efficient future.

Zeolites with uniform micropore have been widely applied in the industrial processes, giving great economic and social benefits. However, current synthesis of zeolites is still not sustainable, which strongly hinder their wide applications. In the past decades, great progresses have been made in sustainable synthesis of zeolites, including design of organic templates, organotemplate-free, solvent-free, fluoride-free, and the combination of organotemplate-free and solvent-free routes. The sustainable routes would significantly reduce the cost and wastes for the production of zeolites, which is potentially important for carbon neutrality in the future.

The iron and steelmaking industry is undergoing significant transformation to meet the rising demand for steel and its components. Generally, the production of steel is a continuous process carried out by using various furnaces, including blast furnaces (BF), basic oxygen furnaces (BOF), integrated furnaces (BF and BOF), and electric arc furnaces (EAF), with distinct operating conditions. Among these, the EAF has emerged as a sustainable solution for steel production due to its utilization of recycled steel scraps and alloys. However, the processing of steel using EAF generates waste industrial slag that requires appropriate reuse to prevent environmental contamination. The EAF slag contains heavy toxic metals such as zinc (Zn), manganese (Mn), nickel (Ni), cadmium (Cd), chromium (Cr), aluminium (Al), posing risks to water and soil if disposed of in landfills, while incineration is both energy-intensive and costly. Therefore, a sustainable and cost-effective solution is imperative. Geopolymer concrete, made from waste materials, offers numerous advantages in terms of strength and durability. Despite this, there is a lack of literature on the effects of EAF slag on geopolymer concrete. The EAF slag has the potential to be utilized as aggregates or as a pozzolanic material in geopolymer composites. Recycling EAF slag in geopolymer composites not only promotes environmental sustainability but also reduces greenhouse gas emissions. This comprehensive review explores the application of EAF slag in geopolymer composites, examining its synergistic effects on the mineralogical composition, morphological characteristics, environmental consequences, and management, as well as its impact on the hardened properties of geopolymer composites.

Indoor air pollution is a major challenge faced by mankind. and tiny negative ions are one of the ideal answers to the problem of indoor air pollution. This method to purify indoor air has received increasing attention in recent years. In this work, a design method of potassium polyacrylate/carbon fiber (UN-PK-CF) composite unidirectional negative ions generating electrode which modified by UiO-66-NH₂ is presented. UiO-66-NH₂ particles are uniformly dispersed within the potassium polyacrylate (PK) hydrogel matrix, facilitating efficient moisture absorption. The natural pores formed during the PK hydrogel curing process effectively store the absorbed water and buffer the release of water in low humidity. One-dimensional carbon fibers, arranged as a skeleton within the hydrogel medium, facilitate rapid charge transfer and discharge from tip to generate negative ions and ROS. The UN-PK-CF electrode developed in this study exhibits outstanding moisture resistance and possesses the capability to harvest and utilize environmental water. Especially under the condition of low humidity, the sterilization rate of the electrode can reach nearly 99% under the coordination of adsorbed water.

This study provides a comprehensive life cycle assessment (LCA) of geopolymer mortar (GM), demonstrating notable environmental, economic, and durability advantages over traditional cement mortar (TCM). The objective is to assess GM's performance and sustainability in comparison to TCM. The production of GM, which utilizes materials like metazeolite (MZ) calcined at 900 °C, red mud (RM), and ground granulated blast slag (GGBS) activated by NaOH and Na₂SiO₃ in a 2:1 ratio, is found to be more efficient. Durability tests revealed that GM's compressive strength improved by 60%–133%, with GMs containing 30% RM and 0.5% basalt fiber (BF) maintaining 36.71 MPa and those reinforced with 0.5% polyethylene fiber (PEF) retaining 35.94 MPa after 270 days of exposure to hydrochloric acid (HCl). When exposed to sulfuric acid (H₂SO₄), the samples with polyethylene fibers showed the least deterioration, retaining 37.27 MPa after 28 days. LCA results indicate that although the raw material costs for GM are roughly double those of TCM, the lifecycle expenses of GM are competitive due to 50% lower production costs, 100% higher transportation costs, and 33% lower maintenance costs. Furthermore, GM generates about one-third of the CO₂ emissions of TCM, representing a 67% reduction. GM also reduces toxicity potential by 70%, emitting fewer phosphates and nitrates. Additionally, GM disposal results in decreased CO₂ and methane emissions and less heavy metal leaching compared to TCM. The optimized GM mix achieved a TOPSIS score of 0.85, significantly higher than TCM's 0.45, highlighting GM's superior sustainability and overall performance.

Herein, chemical-physical co-activation method is developed to prepare polyaniline-derived N-doped porous nanocarbon with useable micropore and small mesopore for guaranteeing high electrostatically adsorptive area and fast ion transport, respectively. K₂CO₃ firstly pre-activates to create appropriate pores, following by CO₂ deep activation for pore development. The resulting coral-like nitrogen-doped porous carbon (NPC_KC) exhibits stable nitrogen-doping, largely efficient surface area, reasonable pore configuration (0.7–3 nm), which are highly desirable for capacitive behaviors. When conducted in aqueous electrolyte, NPC_KC electrode displays a specific capacitance up to 236 F g⁻¹ at 0.5 A g⁻¹ and conspicuous cyclic stability of 96.9 % retention after 10,000 cycles. More meaningful, the organic NPC_KC-based EDLC reaches a 132 F g⁻¹ specific capacitance at 0.2 A g⁻¹ and maintain 120 F g⁻¹ even at 10 A g⁻¹ (90.9 % capacitance retention), greatly surpassing that of commercial AC with similar specific surface area, which exclusively clarifies the significant influence of small mesopores on EDLC energy storage. Meanwhile, it possesses high density energy (40.7 W h kg⁻¹ at 149.6 W kg⁻¹) and power density (23.5 W h kg⁻¹ at 6020 W kg⁻¹), as well as excellent cyclic stability (89.4% of initial capacitance after 10,000 cycles), holding great practical potentials to application in commercial EDLCs.

Supercapatteric devices can combine the advantages of batteries and supercapacitors, addressing their individual limitations in power and energy density. This study focuses on enhancing the electrochemical performance of battery-grade electrodes through the strategic incorporation of transition metal dichalcogenides and transition metal nitrides, specifically tungsten disulfide. Utilizing the magnetron sputtering, we integrated conductive layers of chromium nitride and titanium nitride between substrate and WS₂. Results of thorough electrochemical testing revealed that the initial specific capacity (Q_s) of WS₂ was 600 C/g. However, by incorporating interfacial layers of CrN and TiN, the Q_s was significantly improved 830 C/g and 1230 C/g, demonstrating the substantial impact of interface engineering on overall performance of WS₂. The fabricated supercapatteric devices, demonstrated exceptional performance, with WS₂/CrN//AC achieving Q_s of 950 C/g and WS₂/TiN//AC reaching a Q_s of 1100 C/g. Moreover, WS₂/CrN//AC and WS₂/TiN//AC attained power densities of 6800 W/kg (with 99.8 % capacity retention) and 7108 W/kg (with 99.9 % capacity retention), respectively, and energy densities of 98 Wh/kg and 135 Wh/kg, highlighting the superior performance and stability of WS₂/TiN//AC. Additionally, for examining the diffusive and capacitive behaviors of devices, two different semi-empirical models were further used and compared. This work emphasizes the potential of interface engineering in enhancing the performance of hybrid energy storage (HES) systems.
