To design the photocatalysts with efficient charge separation and transfer property, here we report a benzene ring doped g-C3N4 via one-pot thermal polycondensation of dicyandiamide and 2,4-diaminobenzenesulfonic acid. The carbon-rich benzene ring is embedded into g-C3N4, which enables the asymmetric modification of the heptazine units in g-C3N4 and the extension of the π-conjugate system without altering its long-range order structure significantly. Such molecular structure optimization effectively improves the visible light harvesting and charge carriers' separation ability. A high photocatalytic hydrogen evolution rate and dye degradation performance is achieved under visible light irradiation (λ > 420 nm), which is about 8.4 and 4.4-fold higher than that of pristine g-C3N4, respectively. The reasons for enhanced photocatalytic performance are ascribed to a favorable optical property, suppressed charge carrier recombination, and efficient charge transfer processes. This work provides a green and economical method to functionalize g-C3N4 using low content organic carbon molecule for efficient energy conversion related applications.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500462"},"PeriodicalIF":7.5,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707899","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}

By adjusting the acidity of the solvent, we discovered an alternative mechanism in which the reaction selectivity stops to the hydroxymethylation step, in contrast to previously reported acid-catalyzed pathways leading to the formation of the bisfuranic dimer as major products. One of the keys of this study relies on the reversible derivation of the -CHO group of furfural with N,N-dimethylhydrazone which plays a dual role (1) it restores the nucleophilicity of the furan ring and (2) it reacts with HCHO to form in situ an electrophilic zwiterrionic species stabilized through hydrogen transfer. By means of experimental and theoretical investigations, we discovered that guaiacol can be used as a biobased and safe solvent. Under optimized conditions, the hydroxymethylation of the furan ring of furfural occurs with more than 94% selectivity, at only 50 °C and with a stoichiometric amount of HCHO. A concentrated feed of furfural as high as 25 wt% in guaiacol was employed without impacting the reaction selectivity leading to an improvement of the reactor productivity to about 25 kg/m3/h. The recycling of the N,N-dimehylhydrazone is also discussed.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500318"},"PeriodicalIF":7.5,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699259","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}

Hole transporting material (HTM) is an important part of PSCs, it plays a crucial role in facilitating hole extraction to the anode and blocking electrons from passing through it. Although 2,2',7,7'-Tetrakis(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene (Spiro-OMeTAD) and polytriarylamine (PTAA) are the commonly explored HTMs in PSCs, they need unstable hygroscopic ion dopants and additives to enhance their hole mobility, which can deteriorate the performance/stability of the device. Benefiting from the low-cost synthesis, well batch-to-batch stability, excellent hole mobility and good moisture resistance of the poly(3-hexylthiophene) (P3HT), it has then been used as an alternative HTM in PSC applications. However, the energy level mismatch and the poor interface contact between the perovskite material and P3HT have limited hole transfer to the anode, thus affecting the device performance and stability. In this review, the research progress of the P3HT HTM through interface modification, doping strategy, P3HT derivatives and, etc. is summarized to address the aforementioned problems. Finally, we also provide guidance for further improving the efficiency and stability of P3HT-based PSCs.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500460"},"PeriodicalIF":7.5,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707880","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, benzo[1,2-b:4,5-b']dithiophene, essential for various organic optoelectronic materials, is adopted as the building block for COFs. Hence, a fully conjugated COF BDTT-sp2c-COF and imine-linked COF BDTT-COF are constructed of 5',5''''-(benzo[1,2-b:4,5-b']dithiophene-2,6-diyl)bis([1,1':3',1''-terphenyl]-4,4''-dicarbaldehyde) with p-phenyldiacetonitrile and p-phenylenediamine, respectively. Thorough characterizations and theoretical calculations disclose that BDTT-sp2c-COF is superior to BDTT-COF in terms of specific surface area, photocarrier separation, and electron transfer. As such, BDTT-sp2c-COF enables more efficient photocatalytic sulfoxidation with oxygen than BDTT-COF. The fully conjugated structure guarantees the recyclability of BDTT-sp2c-COF. The blue light-driven sulfoxidation is generally applicable and proceeds selectively via energy and electron transfers over BDTT-sp2c-COF. The fully conjugated COFs are promising to enable photocatalytic reactions.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500552"},"PeriodicalIF":7.5,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690665","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, the low-temperature synthesis of high-quality metal sulfide thin films remains a formidable challenge. Hydrothermal deposition, known for its versatility and cost-efficiency, has been successfully employed to synthesize a variety of materials, yet its application in the preparation of metal sulfide thin films has not been extensively explored. In this study, we develop a hydrothermal deposition method to synthesize five distinct types of metal sulfide thin films, each with well-defined phases and compositions. As a case study, CdS/Bi2S3 thin film was selected and evaluated as photoanode for photoelectrochemical water splitting. Through O-doping and the modification of an ultrathin MoO3 overlayer, the photocurrent density was significantly enhanced from 1.52 mA cm-2 (CdS/Bi2S3) to 2.27 mA cm-2 (CdS/O-Bi2S3), and further to 2.84 mA cm-2 (CdS/O-Bi2S3/MoO3) at 1.23 V vs. reversible hydrogen electrode under AM 1.5G illumination.

Although low-water-content electrolytes have shown promise in mitigating water splitting, their high viscosity and limited ion transport lead to sluggish reaction kinetics. In this work, we propose a water-content gradient electrolyte (GE) by constructing a sandwich-like structure, where two molecular crowding electrolyte (MCE) layers are applied on both electrode surfaces, while a conventional AqE occupies the space in between. The low-water-content MCE effectively suppresses electrode corrosion and dissolution, while the high-water-content AqE improves ionic conductivity. As a result, Zn/Zn symmetric cells utilizing the GE demonstrate exceptional long-term cycling for over 2000 hours at 2 mA cm-2 to 4 mAh cm-2 and over 300 hours at 7.5 mA cm-2 to 15 mAh cm-2. The Zn-vanadium and Zn-manganese full cells in GE also show remarkable longevity, with cycling lives exceeding several thousand cycles at 2 A g-1, and excellent reaction kinetics across varying current densities. Overall, the GE successfully integrates the benefits of both AqE and MCE, leading to enhanced electrode protection without compromising ion transport, thereby offering a new avenue for developing long-lasting aqueous Zn metal batteries.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402737"},"PeriodicalIF":7.5,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690687","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 study, an external magnetic field was introduced into biomass conversion and employed as an effective means to accelerate electrocatalytic oxidation. An ox-NiCoP electrocatalyst was fabricated as an electrocatalyst for the oxidation of 2,5-bis(hydroxymethyl)furan (BHMF) to 2,5-furandicarboxylic acid (FDCA). Upon application of a 0.48 T magnetic field, the conversion of BHMF and the yield of FDCA were increased by 27.8% and 27.5%, respectively. The reaction time was shortened by 3.8 h compared to the reaction without a magnetic field. Kinetic analysis revealed that the magnetic field significantly reduced the charge transfer resistance and accelerated the kinetics of the BHMF oxidation reaction (BHMFOR), achieving a maximum reaction rate constant (k) of 2.53 h-1. The enhancement mechanism was attributed to the magnetic field-induced convection at the electrode surface via the Lorentz force, which improved BHMF diffusion between the catalytic interface and the electrolyte. This work highlights the promotive effect of an external magnetic field in the electrocatalytic conversion of organic molecules.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402715"},"PeriodicalIF":7.5,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690669","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}
