However, direct electrolysis of low-concentration CO2 streams from flue gas suffers from mass transport limitation, resulting in poor Faradaic efficiency (FE). To address this challenge, a gas diffusion electrode featuring a permselective layer is developed that selectively concentrates CO2 at the catalyst interface. The permselective layer integrates a hybrid CO2-philic metal-organic framework Calgary Framework-20 (CALF-20) filler embedded within a tailored polymer matrix. Three polymers-Nafion, polysulfone (PSF), and styrene-ethylene-butylene-styrene-as the polymer matrix to optimize CO2/N2 selectivity and permeability are systematically tested. The CALF-20/PSF composite in the permselective layer achieves a CO2/N2 selectivity of ≈40, enabling a threefold increase in CO partial current density (jCO of -42.7 mA cm-2) with a dilute CO2 feed (10 volume percentage) compared to unmodified electrodes at an applied current density of -50 mA cm-2. In a membrane electrode assembly, the optimized electrode maintains a stable FECO of ≈70% for over 20 h. CO2 uptake studies and structural characterization reveal that strong interactions between the triazole ligands of CALF-20 and the sulfonyl/ether groups of PSF enhance both CO2 transport and electrode durability.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501145"},"PeriodicalIF":6.6,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145342322","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 work explores graphite with recovered silicon (from discarded solar panels) as an anode for both LIBs and LICs. The commercial graphite-recovered silicon (CG-Si) composite displays better electrochemical performance than the pristine graphite, as it is observed that even 5 wt.% of silicon can increase the specific capacity over 150 mAh g-1. The LIB fabricated with CG(95):Si(5) composite as anode and lithium manganese oxide (LiMn2O4) cathode exhibits a maximum energy density of 242 Wh kg-1 with stable cycling performance for more than 750 cycles. On the other hand, the LIC with the same anode and activated carbon cathode displays a maximum energy density of 196 Wh kg-1 with stable cycling performance over 10,000 cycles.

However, the increasing diversity of water pollutants (including biomass derivatives, petroleum byproducts, and plastics byproducts) poses a new challenge to the broad-spectrum detection capability of photoanodes. Herein, calcination transformed the BiVO4 photoanode modified with polytrithiophene (pTTh) and NiOOH cocatalysts, yielding a superhydrophobic BiVO4 photoanode with amorphous nickel oxide (NiOx) and sulfur-incorporated carbon cocatalysts (NiOx/SC). The NiOx/SC/BiVO4 photoanode not only has higher photovoltage through surface defect passivation, but also enhances the selectivity for organic oxidation reactions by suppressing competitive water splitting. The NiOx/SC/BiVO4 photoanode shows excellent detection performance in biomass, petroleum byproducts and plastic byproducts represented by glucose, glycerol, and ethylene glycol, with a linear detection range of 192-19200 ppm (R2 = 0.9953) and a detection limit of 1 mm (S/N = 14). The synergistic effect of the surface defect passivation and the hydrophobic modification provides an efficient and stable solution for broad-spectrum pollutant detection.

However, electrosynthesis methods rely on volatile organic solvents such as acetonitrile to solubilize the reagents, combined with expensive and nonrecyclable electrolytes, which compromise the environmental and economic viability of the approach. Taking the electrosynthesis of 2-arylsulfonylquinolines as representative case, the aforementioned issues by incorporating a deep eutectic solvent that functions simultaneously as the reaction medium and supporting electrolyte are addressed. The method delivers excellent yields, and products are isolated at gram scale via simple water washing and filtration. Interestingly, the eutectic solvent is recovered and reused for up to five cycles without significant loss in reaction yields. In a more general vein, this strategy not only eliminates volatile organic solvents throughout both the reaction and purification stages, but also integrates a recyclable solvent-electrolyte system, there for enabling a fully sustainable electrosynthetic process.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202501779"},"PeriodicalIF":6.6,"publicationDate":"2025-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145336238","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 greenhouse gas emissions associated with the monomer synthesis are investigated by life cycle assessment, and the solvent usage is evaluated.

Consequently, most studies are limited to using lignin model derivatives as substrates. Furthermore, existing literature on synthesizing natural active components from lignin and its derivatives is fragmented and lacks comprehensive reviews. To address this gap, this review first outlines lignin depolymerization methods and their resulting primary aromatic monomers. Subsequently, following the classification framework of NBCs, it systematically evaluates recent advances in synthesizing high-value natural products (e.g., flavonoids, curcumin analogs, and tetrahydroisoquinolines) from lignin and its derived feedstocks using chemo-catalytic, biocatalytic, and chemo-bio cascade strategies.
