Steam reforming of fossil fuels is currently the dominant source of hydrogen production with negative environmental impacts, therefore aqueous phase reforming (APR) of biomass derivatives represents an attractive method for green hydrogen production due to its relatively mild operating temperatures and carbon neutrality. This work provides an overview of the types of catalysts employed in the APR process and their pros and cons regarding their performance and operating conditions. Effects of various catalyst supports, e.g., alloy oxides, composite active metals and ceria, and feedstocks, on performance of the catalysts in APR are also discussed. Recent advances and challenges in APR are summarized into several aspects, (1) doping metals/inorganics into support, (2) structural manipulation and defect induction to support, (3) synthesis of single-atom catalysts, (4) development of more eco-friendly processes or catalysts. The present review can provide guidance for prospective development of efficient catalysts and supports for APR of biomass derivatives for green H2 production.","PeriodicalId":471646,"journal":{"name":"npj Materials Sustainability","volume":" ","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44296-024-00016-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141500490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Potassium - catalyzed graphitization is a more sustainable route and can achieve graphitic carbon formation at temperatures lower than 1000 °C, while enhancing pore formation and creating porous graphitic carbon (PGC). This two-step approach involves carbonization followed by graphitization. However, the compositions of the gaseous products have not been reported in prior studies. In this perspective, the chemical transformations underlying Alkaline Thermal Graphitization (ATG) for the co-production of synthesis gas (H2 and CO) and PGC in a single step, utilizing lignocellulosic biomass, are reported. The presence of graphitic and porous carbon structures in PGC are well suited for supercapacitor applications. This promising approach maximizes resource recovery by upgrading volatile matter to synthesis gas and low value biomass residues to porous graphitic carbon (PGC), thus co-producing sustainable fuels and energy storage materials, while lowering CO2 emissions compared to existing pathways to produce graphite.","PeriodicalId":471646,"journal":{"name":"npj Materials Sustainability","volume":" ","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44296-024-00020-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141500483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, accurate battery health diagnostics and prognostics is challenging due to the unavoidable influence of cell-to-cell manufacturing variability and time-varying operating circumstances experienced in the field. Machine learning approaches informed by simulation, experiment, and field data show enormous promise to predict the evolution of battery health with use; however, until recently, the research community has focused on deterministic modeling methods, largely ignoring the cell-to-cell performance and aging variability inherent to all batteries. To truly make informed decisions regarding battery design in the lab or control strategies for the field, it is critical to characterize the uncertainty in a model’s predictions. After providing an overview of lithium-ion battery degradation, this paper reviews the current state-of-the-art probabilistic machine learning models for health diagnostics and prognostics.

Ionic liquids can disrupt and deconstruct the lignocellulosic biomass network, giving rise to multiple options for valorisation. However, there is still much work remaining to accomplish the scale-up and commercialisation of ionic liquid-based biomass processing. Important issues such as ionic liquid cost and recyclability, among others, need to be carefully addressed. In addition, ionic liquids modify the structure and properties of the recovered materials, impacting potential applications. Due to the complex nature of ionic liquids, where multiple combinations of anions and cations are possible, these issues should be considered for each process and application, making it difficult to generalise for all cases. This perspective covers the main challenges and opportunities in the employment of ionic liquids for biomass processing, both in the biomass processing stage and in the valorisation of the recovered fractions. Among them, we discuss the importance of solvent recovery and costs as two critical issues to consider in biomass processing, as well as the major role lignin condensation plays in hindering ionoSolv lignin valorisation and different approaches to valorise the recovered cellulose.","PeriodicalId":471646,"journal":{"name":"npj Materials Sustainability","volume":" ","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44296-024-00015-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140924941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
