These microfluidic components require significant external energy to apply external forces. Hence, the lack of reliable and sustainable power sources impedes the widespread adoption of these devices. Since the 1970s, photobatteries have been the subject of scientific inquiry with a resurgence in recent years, catalysing the creation of diverse photobattery designs. Among these, paper-based systems have emerged as a particularly promising avenue, offering a potential solution to mitigate the environmental footprint of disposable energy storage devices. Their performance and longevity, however, are heavily dependent on the photoactive battery electrode materials and architectures employed. This comprehensive review article examines the cutting-edge research on bifunctional nanomaterials optimally suited for paper-based lithium-ion photobatteries. The focus is primarily on two-electrode configurations where a single electrode integrates both light harvesting and energy storage capabilities. Such a design is particularly advantageous for electrochemical point-of-care (POC) medical sensors, offering a compact and efficient energy solution. The work highlights the unique requirements and challenges associated with these systems and provides a comprehensive overview of potential photoactive materials. It critically evaluates their performance metrics, such as specific energy, power density, safety, and environmental impact, in the context of solar-powered POC medical sensor applications. Successful case studies and real-world applications are discussed, showcasing their potential to improve healthcare accessibility and quality, particularly in underserved and resource-constrained communities.

This study presents a comprehensive Life Cycle Assessment (LCA) of a chemolithotrophic bacterial platform for simultaneous CO<small>₂</small> mitigation and biodiesel production using <em>Bacillus cereus</em> SSLMC2 cultivated in 10 and 20 L bubble column bioreactors. Unlike phototrophic systems, this process leverages light-independent bacterial metabolism, offering year-round operation, high biomass yield, and compatibility with flue gas as a carbon source. Experimental data were integrated with LCA modeling using Umberto NXT Universal software and the ReCiPe 2016 and CML baseline methods to quantify environmental impacts across cultivation, biomass harvesting, lipid extraction, and transesterification stages. The results identify dewatering and homogenization as major environmental hotspots, contributing significantly to climate change, fossil depletion, and human toxicity categories. Endpoint analysis revealed human health and resource availability as the most impacted areas, primarily due to electricity use and chemical inputs. Cumulative energy demand assessments confirmed that scale-up from 10 to 20 L does not proportionally increase energy use, suggesting promising scalability. Recommendations include replacing centrifugation with membrane-based dewatering, solvent recovery systems, integration of renewable energy, and recycling of CO<small>₂</small> and water.

Levulinic acid (LA), a key platform chemical from lignocellulosic biomass, serves as a versatile precursor for valuable chemicals like γ-valerolactone (GVL), a promising green solvent, fuel additive, and polymer precursor. While ruthenium-based catalysts are effective for LA hydrogenation, conventional systems like Ru/C often suffer from metal leaching and deactivation due to weak metal–support interactions. Current approaches to improve stability, such as using nitrogen-doped carbon supports, involve complex synthesis and synthetic nitrogen precursors. Addressing these limitations, we present a facile and sustainable strategy for synthesizing a robust ruthenium catalyst by directly pyrolyzing marine biomass-derived chitosan to form a self-nitrogen-doped carbon support. This catalyst exhibited superior stability and excellent recyclability in the aqueous-phase hydrogenation of LA to GVL, surpassing conventional Ru/C while maintaining activity comparable to that of leading Ru catalysts supported on N-doped carbon. Unlike other N-doped carbon supports, our method avoids synthetic N-dopants and tedious procedures, making it inherently more sustainable. Detailed characterization <em>via</em> XPS and H<small>₂</small>-TPR revealed strong metal–support interactions, facilitated by intrinsic nitrogen functionalities, effectively stabilizing the ruthenium species. This study also identifies the critical role of graphitic and pyridinic nitrogen species in controlling catalytic activity and elucidates the importance of optimizing nitrogen species and content in tailoring chitosan-derived supports. The proposed mechanism describes how Ru–N centers activate hydrogen and LA, with basic nitrogen sites aiding the dehydration step to GVL. Overall, this work features the potential of chitosan derived carbon as a sustainable and tunable support for efficient biomass hydrogenation catalysts and offers fundamental insights into the role of nitrogen doping in tailoring catalytic performance.</p>","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 21","pages":" 5921-5930"},"PeriodicalIF":4.1,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145335382","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}
