It is found that, upon replacing imine linkage with cyanated vinylene, under the irrdation of visible light, the H2O2 production rates (HPR) considerably increases from 2261 μmol h-1 g-1 to 7613 μmol h-1 g-1 in pure water and O2 atmosphere without the assistance of any sacrificial agent. Even though in air atmosphere, its HPR value still reaches 6339 μmol h-1 g-1 with good recyclability. The improved catalytic performance is attributed to the the enhanced polarity through the incoporation of strong polar sulfone or cyano groups in the COF frameworks, which brings about the effective separation of photogenerated electrons and holes, high photocurrent intensity and low charge resistance as well as the increased surface hydrophilicity. The photocatalytic mechanism is studied by means of the theoretical calculations and comparative experiments conducted under the aerobic and anaerobic conditions in the presence and absence of the various scavengers for electron, hole, superoxide radical and hydroxyl radical in the reaction system.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500624"},"PeriodicalIF":7.5,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144109225","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}

Research studies are most generally carried out with pure gas streams of CO2, while the available real sources of CO2 are gases coming out from industrial plants and containing a low share of CO2, and a great diversity of impurities including nitrogen and sulfur oxides. Here, we show that a molecular catalyst, [Rh(bpy)(Cp*)Cl]Cl (bpy = bipyridine, Cp* = pentamethylcyclopentadienyl), catalyzes CO2RR to formic acid using a quasi flue gas (5-10% CO2 and 100 ppm NO2 or 50 ppm SO2) with substantial selectivity. This is made possible thanks to the modification of the cathode surface with a positively charged imidazolium layer, which greatly favors CO2RR over competing reactions, proton, NO2 and SO2 reductions. These results highlight the potential of combining molecular catalysis and electrode surface modification for electroreduction of diluted CO2 without prior carbon capture or purification.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500392"},"PeriodicalIF":7.5,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144101270","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}

As the world strives for net-zero emissions, advancing plastic recycling technologies has become a global priority. Pyrolytic liquefaction is a promising approach for recovering chemical feedstocks, including fuel fractions, from waste plastics, potentially substituting petroleum resources. Since the 1970s, research on pyrolytic liquefaction has progressed globally, and several industrial-scale plants are now in operation. However, to accelerate the transition to a circular economy, it is crucial to bridge the knowledge gap between lab-scale research and industrial-scale implementation of pyrolysis-liquefaction technologies. This review provides a comprehensive analysis of the current state of plastic recycling, the progress and challenges in cutting-edge lab-scale research on pyrolytic liquefaction, alongside the latest trends in industrial-scale liquefaction projects. It reveals that pyrolytic liquefaction of a wide range of plastics-including halogenated plastics and poly(ethylene terephthalate)-has been extensively studied at the laboratory level. In contrast, industrial-scale operations often focus on more common, easily pyrolyzed plastics and generally avoid the use of catalysts. This highlights the urgent need to develop robust, reusable, and cost-effective catalysts, as well as optimized process designs, to expand the range of plastic feedstocks suitable for industrial-scale pyrolysis plants.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500210"},"PeriodicalIF":7.5,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144109219","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}

However, their synthesis often requires complicated reaction conditions limiting their scalability. In this study, we present a straightforward and scalable synthesis method for a BaAl2O4-ye-y/C oxy-electride composite via carboxylic acid complexation (pseudo-Pechini) followed by carbothermal reduction. The resulting composite exhibits significant surface area, of ~41 m2 g-1, which is considerably higher than the electrides prepared by solid-state synthesis. Upon loading with ruthenium, the BaAl2O4-ye-y/C composite demonstrated excellent catalytic activity for ammonia synthesis, achieving rates of 3090 μmol g-1catalyst h-1 with 0.6Ru/BaAl2O4-ye-y/C, and 3737 μmol g-1catalyst h-1 with 1.1Ru/BaAl2O4-ye-y/C at mild reaction conditions (400 °C and 1 bar). Comprehensive characterization through XRD, Raman spectroscopy, SEM, and STEM-EDS confirmed the textural and structural properties of the catalyst, while iodometric titration method and EPR analysis confirmed the electride-like nature of the resulting composite. The results reported in this work highlight a straightforward approach for the design of electride-based composite material displaying superior catalytic properties for green ammonia synthesis.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500682"},"PeriodicalIF":7.5,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144109263","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, we have demonstrated a hydrophobic tetrapodal receptor Se4Me-PF6, that exhibits iodine adsorption from an aqueous phase via chalcogen bonding (ChB) interaction. In the solution phase, NMR studies reveal that Se4Me-PF6 selectively recognizes iodide (I-) over other anions. On the other hand, in the solid state, selenoimidazolium building units of Se4Me-PF6 facilitate self-assembly into a porous 1D supramolecular ChB framework, enabling efficient iodine adsorption. Consequently, Se4Me-PF6 has propelled the rapid adsorption of iodine, with a high kinetic rate of 2.10 × 10-3 g·mg-1·min-1, while maintaining its effectiveness under competitive environmental conditions, including pH variations and the presence of interfering anions. Mechanistic investigations using XPS, and DFT studies indicate that iodine capture occurs via a combination of ChB interactions and electrostatic forces provided by the selenoimidazolium motifs. Importantly, Se4Me-PF6 demonstrates its potential as a stationary phase for column-based iodine removal, highlighting its applicability in real-world scenarios. Thus, these findings offer a promising approach for developing iodine adsorbent materials.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500751"},"PeriodicalIF":7.5,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144092307","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}

Nevertheless, this approach faces limitations due to outlet CO generation and catalyst degradation. This work fabricates a series of CuFeOx-based catalytic oxygen carriers (COC) with various Cu-to-Fe ratios for lattice oxygen-induced methanol reforming, which goes through lattice oxygen-induced methanol reforming → catalytic steam methanol reforming → oxidative steam methanol reforming. It is revealed that the lattice oxygen mobility can be tuned by modulating the Cu-to-Fe mole ratios. Of the synthesized COCs, Cu2Fe3 shows the highest catalytic activity. It is supposed that CuO in COC provides lattice oxygen with catalytically site of Cu0, while CuFe5O8 contributes relatively stable Cu+, synergistically inducing highly efficient oxidative steam reforming of methanol. Specifically, a H2 production rate of 93.9 mmol·H2·h-1 g-1·COC·at 220 °C is achieved with relatively stable redox looping within 20 cycles.

This reaction is a route to glycolic acid, which is a key component of biodegradable packaging. Using a combination of cyclic voltammetry, EDX and XRD analysis, we find that a 3:1 Pd:Ag ratio gives optimal results. We show that the oxidation of ethylene glycol on palladium occurs between 0.3 and 1.2 V vs. RHE, and depends on the presence of a Pd(0) active site. Electrochemical Impedance Spectroscopy experiments show that the charge-transfer resistance (RCT) follows the same trend as EGOPd activity, with the 3:1 Pd:Ag electrode having the lowest RCT. Electrolysis with this electrode at 0.705 V vs. RHE, where Pd is reduced, results in glycolate production with no overoxidation to formate or oxalate. We then move to a flow setup under industrial conditions, and show that the Pd-Ni electrode yields >80% FE to glycolate for over 140 h. Long-term electrode deactivation can be overcome in this system by a periodic self-refresh cycle.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500724"},"PeriodicalIF":7.5,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144101164","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}
