These liquors require treatment before being discharged; otherwise, they negatively impact the environment. Herein, spent liquors from aqueous ammonia pretreatment of poplar wood are characterized for phenolic content via liquid chromatography-mass spectrometry and nuclear magnetic resonance spectroscopy. The main phenolics are phenol, p-hydroxybenzamide (pHBAm), and p-hydroxybenzoic acid (pHBA), of which pHBAm and pHBA are produced from the ester-linked p-hydroxybenzoates in poplar wood. Phenol is produced from pHBA via decarboxylation. The potential biotransformation of the extracted phenolics into 2-pyrone-4,6-dicarboxylic acid (PDC) is assessed using an engineered strain of Novosphingobium aromaticivorans DSM12444 (PDC strain). Biotransformation of pHBAm to PDC is shown to be possible in the presence of pHBA, but not when pHBAm is the sole phenolic substrate, this is the first reported observation of N. aromaticivorans producing PDC from an aromatic amide. The phenol present is not transformed to PDC and does not inhibit PDC production. This study demonstrates that the phenolic amide in spent liquor from ammonia pretreatment can be valorized via biotransformation using N. aromaticivorans, which adds to the growing versatility of N. aromaticivorans as a microbial chassis for converting plant-derived compounds to useful products.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2500881"},"PeriodicalIF":6.6,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145028683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The performance of the three Ionosolv-ILs triethylammonium hydrogen sulfate ([TEA][HSO4]), N,N-dimethylbutylammonium hydrogen sulfate ([DMBA][HSO4]), and tributylmethylphosphonium methyl sulfate ([TBMP][MeSO4]), mixed with methanol (MeOH) (30/70 wt%), is evaluated by methyl formate yield from extracted hemicellulose and lignin as well as purity of the bleached cellulose pulp in the presence of various Keggin-type POMs. The redox-balanced H8PVMnMo10O40 POM catalyst in [TBMP][MeSO4]/MeOH emerge as the most effective combination, achieving 20% methyl formate yield from commercial beech wood. The glucan content in the bleached cellulose-enriched solid consisted is over 90%, demonstrating that the use of MeOH drastically improved lignin extraction in parallel with full hemicellulose extraction. The cellulose is highly susceptible to enzymatic hydrolysis, generating a pure and concentrated cellulosic glucose stream. The formed solid catalyst complex is examined in detail to reveal its chemical nature as POM-IL-complex. The approach is applicable to disparate types of lignocellulosic biomass, including hardwood, softwood, and grass.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501034"},"PeriodicalIF":6.6,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145028641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dehydration reactions are characterized by the formal removal of water in the course of the transformation, and they are among the most fundamental types of reactions found throughout chemistry. Examples are esterification reactions, amidation reactions, and the synthesis of carbon-heteroatom multiple bonds. In general, dehydration reactions are not considered to be redox reactions, because no oxidation states change in the substrate from which water is eliminated or in the dehydration reagent that is utilized. At first glance, there does not seem to be a link between dehydration reactions and redox chemistry. In recent years, however, it has been demonstrated that dehydration reactions can be carried out by electrolysis. Given the enormous importance of dehydration reactions from academic to technical scale, electrochemical dehydration reactions offer a more sustainable approach to such transformations. In this review, the recent progress is surveyed and the opportunities of this new and evolving field are highlighted. Electrochemical dehydration reactions are an interesting new discipline in the emerging domain of electroorganic chemistry, which is currently experiencing a remarkable renaissance to establish itself as a 21st-century technique.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501552"},"PeriodicalIF":6.6,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145028627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a new organic electrode material is described, which is obtained via ionothermal polymerization of low-cost starting materials, melem (2,5,8-triamino-tri-s-triazine) and perylenetetracarboxylic dianhydride (PTCDA). The resulting networked polymer Melem-PDI exhibits favorable thermal and electrochemical properties, prompting investigation into its performance as a positive electrode material in rechargeable lithium and magnesium batteries. A hybrid material with carbon nanotubes (Melem-PDI-CNT) is found to exhibit-excellent cycling stability in Li-ion batteries at a current rate as high as 500 mA g-1 for 5000 cycles. While the Li-ion storage is based on a pseudocapacitive mechanism, a diffusion-controlled mechanism is observed in magnesium batteries. This work underscores that classic dyes (here: PDI) can be repurposed for energy storage, once they are integrated into suitable polymer topologies and brought into nanoscale contact with conductive materials.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2500967"},"PeriodicalIF":6.6,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145013473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a possibility of turning this challenge into an opportunity by plastic upcycling. In this work, the potential of bismuth oxychloride (BiOCl) as a heterogeneous catalyst for the glycolysis of polyethylene terephthalate (PET) is reported. Among the catalysts prepared, Bi-Co nanoplates showed the highest PET conversion and bis(2-hydroxyethyl) terephthalate (BHET) yield. Main reasons for the enhanced catalytic activity are the presence of more surface hydroxyl groups, exposed 001 crystal facets, and abundant Lewis acidic sites (Bi3+). Further, the Response Surface Methodology (RSM) was used to assess the effectiveness of the synthesized catalyst. The regression model developed shows that the PET conversion and BHET yield are significantly affected by the amount of ethylene glycol, the reaction time, the reaction temperature, and the amount of catalyst. The BHET yield reaches 70.25% using Bi-Co catalyst under optimal conditions. The fundamental glycolysis mechanism and elements governing product selectivity toward BHET are established. A techno-economic analysis showed that BiOCl nanoplates are the ideal candidates for the large-scale glycolysis of PET. This work presents the immense potential of BiOX for thermal catalytic processes.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2501196"},"PeriodicalIF":6.6,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145013464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
