In this paper, we present a new version of the atmospheric pressure chemical vapor deposition technique designed to improve the reproducibility of a-Si:H deposition. With this new tool, we explore ways to improve the quality of the material. The films can be prepared using pure trisilane as a precursor; frequently, however, trisilane is diluted with cyclooctane for better handling and process control. Currently, the influence of this dilution on the film quality is not well understood. In our work, we investigate and compare both precursor strategies. This paper presents a comprehensive analysis of the effects of cyclooctane dilution, deposition temperature, process duration, and precursor amount on the structure stoichiometry and electronic properties of the resulting films. The analysis was performed using a range of techniques, including Fourier transform infrared spectroscopy, electronic spin resonance spectroscopy, Raman spectroscopy, ellipsometry, secondary ion mass spectrometry, and conductivity measurements. For films deposited with pure silane, we found a low oxygen (O) and carbon (C) impurity incorporation and an adjustable H content up to 10%, resulting in a photosensitivity of up to 10<small>⁴</small>. Dependent on the dilution and deposition temperature, the films deposited with cyclooctane dilution showed various amounts of C incorporation, culminating in an a-Si:H/a-SiC:H structure for high temperatures and dilutions.

In this study, we introduce a low-cost, air-processible method—Cooled Moisture Condensation (CMC)—to enhance the coverage of MeO–2PACz SAMs on fluorine-doped tin oxide (FTO) substrates. By cooling the FTO in ambient air, moisture condenses uniformly, increasing surface hydroxyl (–OH) groups and reducing oxygen vacancies, which improves SAM bonding and coverage. Conductive Atomic Force Microscopy (C-AFM) and Scanning Electron Microscopy (SEM) confirm enhanced SAM coverage, reduced leakage current, and improved perovskite film quality.

Catalytic fast pyrolysis (CFP) can convert lignocellulosic biomass into relatively stable bio-oil that can be selectively transformed to various transportation fuels through hydroprocessing under conditions of different severities. In this contribution, two CFP oils produced from pine-based feedstocks over different types of catalysts (<em>i.e.</em>, ZSM-5 and Pt/TiO<small>₂</small> catalysts) were hydrotreated at 125 bar in a non-isothermal process with a maximum temperature of 385 °C over a sulfided NiMo/Al<small>₂</small>O<small>₃</small> catalyst to produce SAF with high cycloalkane concentrations of 89–92 wt%. Cycloalkanes are an important component of jet fuel with advantageous fuel properties, such as high energy density, low sooting, and potential for replacing aromatic hydrocarbons to provide good seal swelling properties. The hydrotreating process successfully converted 91–92% of the biogenic carbon in the CFP oil intermediates to liquid-phase hydrotreated products. Through distillation, 39–40 wt% of the hydrotreated oils were collected in the jet-fuel range as SAF fractions. The rest of the hydrotreated product could be valorized as fuels (<em>e.g.</em>, diesel) or chemicals. The SAF fractions with oxygen contents below the detection limit (&lt;0.01 wt%) met ASTM D7566 finished fuel blend and D4054 Tier 1 specifications with respect to density, lower heating value (LHV), volatility, flash point, and freeze point. These results indicate hydrotreating lignocellulosic biomass-derived CFP oil as a promising pathway to produce high-quality SAF rich in cycloalkanes. Continued research is required to increase the SAF yield by process improvements, such as increased CFP oil yields, and an enhanced production of SAF-range molecules <em>via e.g.</em>, cracking of high-molecular weight compounds either during CFP or hydrotreating, as well as evaluation of a broader range of jet fuel properties and performance requirements.</p>","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 23","pages":" 5504-5513"},"PeriodicalIF":5.0,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/se/d4se01151a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
