As results, the formation of active sites (NiOOH) and the adsorption of glucose are simultaneously facilitated in Ni(OH)2MoO3-x, which effectively converts glucose to formic acid (FA) with remarkable yield and Faraday efficiency (≈90.5 and 98%, respectively), far superior to conventional β-Ni(OH)2 catalyst (≈22.5 and 58.9%, respectively).

In this article, the recent research progress in ECO2RR for methane production is systematically reviewed. First, the theoretical foundations of ECO2RR and the key reaction mechanisms involved in methane production are elaborated upon. Then, catalyst design strategies are summarized aimed at enhancing methane selectivity and activity, including 1) fine tuning of crystal surface, morphology, and size; (2) defects engineering; and (3) tandem catalysis. In addition, the role of modulating microenvironment is reviewed, focusing on the effects of pH, ionic effects, and CO2 concentration.

Nevertheless, the conventional synthesis method restricts the synthesis of nanostructures in TMS and the investigation of the synthesis mechanism. In view of the above considerations, we propose a novel synthesis method: liquid-assisted sintering. This approach retains the advantages of solvothermal synthesis of nanomaterials while providing insight into the reaction mechanism and avoiding densification from sintering. The synthesis mechanism of this method is also revealed by the synthesis of Ni3S4/Co3S4. The synthesis process is influenced by Le Chatelier's principle, forming a three-step cyclic reaction. This in turn leads to cathode materials with heterojunction structures The cathode material possesses excellent electrochemical properties. The best devices can achieve an energy density of 57.7 W h kg-1 at a power density of 102.4 W kg-1 and maintain an energy density of 21.7 W h kg-1 at a power density of 3547.8 W kg-1.

In this study, we revisit dithiin fused dilithium naphthazarin (5,8-dihydroxy-1,4-naphthoquinone) (DNP-Li) as a high-voltage Li-ion organic cathode and evaluate its performance in conjunction with localized high-concentration electrolyte (LHCE). DNP-Li exhibits remarkable air and thermal stability, a high operating potential of 3.55 V vs. Li+/Li, and a specific capacity of 232 mAh g⁻¹, positioning it as one of the most promising candidates among Li-ion organic cathodes. Furthermore, the electrochemical behavior of DNP-Li is strongly influenced by the electrolyte composition, giving distinct two-plateaus or four-plateaus voltage profiles accompanied with reversible or irreversible phase transition in carbonate-based or LHCE electrolyte formulations, respectively. The reduced solubility of DNP-Li-based redox intermediates in LHCE enhances cycling stability, achieving a capacity retention of 85% after 50 cycles at 0.1C and 75% after 160 cycles at 0.5C, demonstrating a significant improvement compared to the carbonate-based electrolyte.

However, the strong Coulomb interactions on Mg2+ cations lead to inefficient storage and transport in the cathode, which severely restricts the actual performance of rMIBs. Herein, a virtual screening of the 1D material database (C1DB) is proposed to identify novel rMIB chalcogenide cathodes with large voids for relieving the Coulomb forces. By referring to the representative VS4 material, three potential 1D chalcogenide materials (SiS2, GeS2, and SiSe2) with optimized Coulomb interactions are ultimately screened out for rMIB cathodes. In addition, further theoretical analyses on geometry, electronic structures, and atomic charges reveal the significant roles of the large specific pore volume, low bond covalency, and mildly oxidizing anion element in optimizing rMIB cathode materials. Overall, this work may inspire future experimental and theoretical investigations, potentially accelerating breakthroughs of rMIB and other similar metal-ion batteries.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2500181"},"PeriodicalIF":7.5,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707903","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}

To design the photocatalysts with efficient charge separation and transfer property, here a benzene ring-doped g-C3N4 via one-pot thermal polycondensation of dicyandiamide and 2,4-diaminobenzenesulfonic acid is reported. 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 reason for enhanced photocatalytic performance is ascribed to a favorable optical property, suppressed charge carrier recombination, and efficient charge transfer processes.

By adjusting the acidity of the solvent, an alternative mechanism is discovered 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 a major product. One of the keys of this study relies on the reversible derivation of the -CHO group of furfural with N,N-Dimethylhydrazine 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, this reaction is optimized and it is discovered that guaiacol can be used as a bio-based and safe solvent. Under optimized conditions, the hydroxymethylation of the furan ring of furfural occurs with more than 95% selectivity, at only 50 °C and with a stoichiometric amount of HCHO. A concentrated feed of furfural as high as 40 wt% in guaiacol can be employed without impacting the reaction selectivity, leading to an improvement of the reactor productivity to about 25 kg m-3 h-1. The recovery of the reaction products and the recycling of the N,N-dimehylhydrazone are also discussed.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2500318"},"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}

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.
