In efforts to clarify structure-activity correlations, sets of these two polymorphs are characterized to determine their polymorphic purity, surface areas, and acidic properties. Initial catalytic investigations encounter considerable challenges, as substantial deactivation is observed when employing ethyl acrylate as a substrate - an issue attributed to the polymerization of the generated acrylonitrile. Stable catalyst performance is achieved using the saturated substrate and ethyl propionate. Investigating the nitrilation reaction using this saturated substrate displays significantly higher catalytic activity on the anatase polymorphs compared to the rutile. The catalytic activity correlated well with the total acid density, and correlations occur independently for both anatase and rutile, emphasizing the impact the catalyst polymorph has on this reaction.

Existing toxicity studies show inconsistent results due to the choice of different test organisms and methods, synergistic effects between DES components, and their interactions with culture media. This study introduces the haloarchaeon Haloferax mediterranei as a novel model to assess both the toxicity and biodegradability of acetylcholine chloride (AcChCl) and choline chloride (ChCl) based DESs. Unlike other models that may not accurately reflect the environmental risks posed by halide-rich DES residues, H. mediterranei is an extremophile naturally adapted to high-salt and high-halide environments. DES concentrations of up to 300 mM were well tolerated. AcChCl-based DESs inhibited growth, likely via medium acidification due to some DES components hydrolysis, ChCl: acetamide has partial effects depending on acetamide concentration, and ChCl: ethylene glycol shows no toxicity. The haloarchaeon metabolizes specific DES components, reducing environmental impact. Urea and AcChCl: urea (100 mM) serve as nitrogen sources, while AcChCl-based DESs are consumed as carbon sources, likely due to the presence of acetate.

However, the performance of wide-bandgap PSCs remains challenging, primarily due to nonradiative recombination at the interfaces. An interlayer applied at the buried interface between the hole transport layer and the perovskite in a p-i-n architecture can play a pivotal role, as it is critical for efficient charge transport, extraction, and the formation of high-quality perovskite films. In this work, a donor-acceptor architectural quinoxaline-based organic interlayer specifically designed for the interface between NiOx and wide-bandgap perovskite is introduced. The incorporation of this interlayer effectively passivates defects at the perovskite interface, leading to improved charge carrier extraction and a substantial reduction in nonradiative recombination, while also enhancing the overall quality of the perovskite film. Moreover, the high dipole moment of QxNN increases the built-in potential of the device, further contributing to enhanced charge extraction. Notably, PSCs incorporating the organic interlayer exhibit a remarkable increase in power conversion efficiency, from 17.5% to 20.0%, while maintaining their performance over 500-h under ambient conditions.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2500543"},"PeriodicalIF":7.5,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144273786","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}

Herein, a nonmetallic plasmonic BiOx photocatalyst with tunable oxygen vacancies is reported that enables continuous adjustment of infrared absorption from 700 to 1700 nm. By varying calcination temperature, the carrier concentration and localized surface plasmon resonance (LSPR) response are effectively modulated. Combined X-ray photoelectron spectroscopy (XPS), Mott-Schottky analysis, and control experiments reveal that gradient oxygen vacancies play a key role in regulating plasmonic intensity and catalytic activity. The optimized BiOx-180 °C catalyst achieves efficient CO2 reduction under near-infrared illumination (>800 nm), delivering a total production rate of 3 μmol g-1 h-1 with 50.5% selectivity toward C2 products, which is 2.7 times higher than under UV-vis light. Moreover, under full-spectrum illumination, BiOx exhibits an increased total product yield, demonstrating the synergistic effect between interband transitions and plasmonic excitations. Quasi-in situ XPS, light-assisted Kelvin probe force microscopy, and in situ diffuse reflectance infrared Fourier transform spectroscopy further reveal that the LSPR effect facilitates CC coupling pathways, promoting the generation of C2 products.

To understand the molecular basis of achieved improvements and factors limiting the degree of depolymerization, intra- and intermolecular interactions of various enzyme-substrate complexes are analyzed by incremental docking of PA 6 tetramers and MD simulations.

The unique delocalized charge distribution of the weakly binding cyanamide-containing monomer, combined with the high dipole moment of the zwitterionic monomer as a decoupling agent, facilitates Li+ ion dissociation and reduces the activation energy for ion hopping.
