Herein, based on density functional theory (DFT) calculations on 192 fluorinated carbonate derivatives and data analysis, a multiple linear regression (MLR) was deduced to correlate HOMO energy with the simple structural parameters, i.e., the number of fluorine atoms on α-, β-, and γ-C sites of the carbonates, and the number of <i>β</i>-alkyl (denoting the branching of the <i>α</i>-alkyl group) of the carbonate group, as descriptors.

According to the dual-cycle mechanism: in the aromatic-based cycle, the aromatic hydrocarbon pool (polymethylbenzene) is formed, mainly producing ethylene, aromatics, and partial propylene; in the alkene-based cycle, the olefin hydrocarbon pool (mainly higher olefins) is formed, producing C₃₊ olefin products. However, under the influence of various factors such as the acidic properties and pore confinement effect of the zeolite, the types of hydrocarbon pool (HCP) species in the dual-cycle pathways and the corresponding dominant products will be different. Therefore, it is crucial to discern the role of aromatics/olefins, whether if it is active aromatics/olefins HCP or the inert coke precursors. At medium and low temperatures, adamantane (ADH), whose role in the dual-cycle pathway is still controversial, has been found on both CHA and MWW zeolites. In this paper, ADH was preadsorbed on the H-MCM-22 zeolite; combined with pulsed ¹²C-methanol/¹³C-methanol isotopic switching experiments and direct ¹³C-methanol isotopic pulsing experiments, it confirmed that ADH undergoes C─H bond cleavage and improves the hydrogen transfer reaction, playing a cocatalytic role in the MTH reaction; In addition, the C atoms of ADH also incorporate into ethylene, and into some aromatic HCPs, which eventually promoted the aromatic-based cycle and inhibited the olefin-based cycle. Moreover, partial carbon of ADH was incorporated into naphthalene as coke precursor in MTH reaction. It also suggested the participation of ADH in accelerating the deactivation of the catalyst. The clarified role of ADH in the dual-cycle pathway of the zeolite catalyzed MTH reaction can provide some inspiration on tuning the dual-cycle pathway and obtaining target products.</p>","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 9","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143513494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the effects of phenylethylammonium bromide (PEABr) passivation concentration, varying light conditions, and temperature on the electrochemical properties of MAPbBr₃ SCs. Results showed that increasing PEABr passivation concentration significantly enhanced charge transfer dynamics and reduced interfacial resistance. Passivation concentrations, particularly 20 mM and 50 mM, effectively reduced resistance and ion migration rates, enhanced charge carrier mobility, and minimized recombination losses. Charge transfer resistance exhibited a substantial dependence on passivation concentration and a moderate dependence on light type under various light exposures. The ion activation energy increased from 0.21 eV to 0.40 eV after passivation, indicating effective suppression of ion migration and improved electrochemical stability. Phase angle analysis from Bode plots further demonstrated enhanced charge transfer and capacitive behavior under all tested conditions with higher passivation concentrations.
