In this study, the disproportionation and transalkylation reactions of MLCT-related model compound, i.e., 2,6-DMP, in phenol over zeolite catalysts are investigated using a fixed-bed reactor for sustainable new option to utilize MLCT-derived phenolic mixtures. Reactivity is promoted at high temperatures and associated with zeolite acidity and pore structure. Since disproportionation and transalkylation reactions have certain spatial requirements, the micropores of MFI-type zeolite may cause spatial barriers that make it difficult to carry out the reactions. MCM-22, characterized by MWW-type zeolite, maximized the conversion of 2,6-DMP due to its strong Bronsted acidity and large mesopore volume. FAU-type zeolite HY with a 3D large 12-ring through-channel shows relatively small spatial confinement and certain molecular sieving ability, which enables bimolecular reactions while allowing cresols to flow out of the pores efficiently to obtain the highest cresol selectivity. The addition of phenol significantly inhibits the spontaneous disproportionation of 2,6-DMP to tricresol. Besides, o-cresol dominate the cresol products, suggesting that the selectivity of o-cresol is kinetically controlled.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"8 11","pages":""},"PeriodicalIF":6.5,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141522297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Solutions of NaClO4 or NaCF3SO3 in tetraglyme are investigated in terms of thermal stability, ionic conductivity, Na+-transference number, electrochemical stability, stripping-deposition ability, and chemical stability in Na-cells. Subsequently, versions of the electrolytes doped with fluoroethylene carbonate (FEC) are prepared using 0.5, 1, 2, or 3% additive weight concentrations, and evaluated by adopting the same approach used for the bare solutions. Scanning electron microscopy (SEM) provides morphological details of the passivation layer formed on the Na electrodes, while X-ray photoelectron spectroscopy (XPS) sheds light on its composition. The most relevant achievement of the FEC-added electrolyte is the suppression of the polysulfide shuttle in Na–S cells using a cathode with 70 wt.% of sulfur in the composite. This result appears even more notable considering the low amount of the additive requested for enabling the reversible cell operation. The solutions using 1% of FEC show the best compromise between cell performance and stability. Cyclic voltammetry (CV) displays the potential region related to the FEC electrochemical process responsible for Na–S cell operation. The understanding of the electrolyte features enables additional cycling tests using sulfur cathode with an optimized current collector, increased specific capacity, and coulombic efficiency.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"8 11","pages":""},"PeriodicalIF":6.5,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141522296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the problem of high viscosity and susceptibility to side reactions with metallic lithium has been the subject of criticism. To solve the issue of incompatibility with lithium, researchers adopted a high-concentration electrolyte, namely solvent-in-salt, which allows the anions in the lithium salt to preferentially contact the surface of the lithium metal and react to form an SEI film to block the reaction between sulfone solvents and lithium. However, the issue of high viscosity is particularly severe. This work proposes a new solvent model called “solvent-in-diluent” electrolyte to address both of these issues simultaneously, different from previous models of salt-in-solvent, the model not only effectively prevents sulfone contact with lithium metal surfaces, but also maintains a capacity retention rate of 82% after 500 cycles in the voltage range of 2.8–4.6 V, additionally, the temperature range in which the battery can operate using this electrolyte model has been extended (−20–60°C). This work proposes a new solvent model and challenges the minimum concentration of high-voltage electrolytes (0.04 m), providing a new approach and possibility for studying high-voltage electrolytes.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"8 11","pages":""},"PeriodicalIF":6.5,"publicationDate":"2024-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141529134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the successful synthesis of uniformly-sized, spherical Pt–Cu alloy nanodendrites are reported using a novel visible light-driven photoreduction method that exploits fluorescein as an excited state photosensitizer. Factors influencing the structure and morphology of the PtCu alloy nanodendrites are systematically explored, including pH, Pt4+ and Cu2+ concentrations, Pt:Cu molar ratio, Light emitting diode (LED) light irradiation time, light intensity, concentration of hexadecyl trimethyl ammonium bromide (CTAB), and concentration of triethylamine (TEA). The experiments reveal a simultaneous photoreduction/galvanic replacement mechanism for PtCu alloy nanodendrite formation. Importantly, the PtCu alloy nanodendrites are easily separable from the reaction solution, facilitating their use as electrocatalysts for the electrocatalytic nitrite reduction reaction (eNO2RR) to ammonia and also the nitrogen oxidation reaction (NOR) to nitrate. The PtCu alloy nanodendrites outperforms a commercially available Pt nanoparticle catalyst in both NO2RR and NOR, validating the approach.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"8 9","pages":""},"PeriodicalIF":6.5,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141522300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
